scope of aquatic microbiology

Bacteria have a profound influence on various human endeavours including health, industry, agriculture, etc. Most viable air born<; particles are spores of different organisms which are to some extent suited for survival in such an environment. The microorganisms possess three out­standing qualities: (i) Rapid growth in large quantities in suitable organic substrate, (ii) Maintain physiological constancy of growth to produce approximate amounts of products, and. Some of the diseases like tuberculosis, leprosy, typhoid, etc. What are the characters Mendel selected for his experiments on pea plant? Mass cultivation of these organisms offers a food supplement for animals bridging ‘the protein gap’. The microorganisms that inhabit the soil exhibit different types of associations or interactions which depend upon the biotic and abiotic components of soil. Blue-green algae in mass scale for the use as ferti­lizers can be cultured by (i) tank culture method, and (ii) dry sand culture method. When this happens, much of the available dissolved oxygen is consumed by aerobic bacteria, robbing other aquatic organisms of the oxygen they need to live. Since the constituent elements of carbohydrates, proteins, fats, etc. But in the mean time in 1658 Kircher designated the disease inducing living organisms as ‘worms’, which according to him are invisible to the naked eye. (With Methods)| Industrial Microbiology, How is Cheese Made Step by Step: Principles, Production and Process, Enzyme Production and Purification: Extraction & Separation Methods | Industrial Microbiology, Fermentation of Olives: Process, Control, Problems, Abnormalities and Developments. Importance of microbiology in nursing practice. Scope and Applications of Microbiology. It is con­cerned with the form, structure, metabolism, growth, reproduction and identifica­tion of microorganisms. As there are lots of subjects of research within the field of Marine biology, one can choose a location of a certain rate of interest in which to specialize. F.M. The duration of the use of phos­phobacterin is longer than that of azotobacterin, for example, a packet of phospho­bacterin can be used for 12 months while azotobacterin must be used within two months. True, numerous organisms expell their spores forcibly for distances ranging from a few to many milli­metres by active mechanisms, but most air borne microorganisms have no special structures to facilitate their dispersal into the atmosphere. Since Azotobacter is not effective in acid soils, these should be limed. 2006). But Antony van Leeuwenhoek (1632-1723) was the first person to report descriptions of microorganisms in detail. Phosphobacterin when used with farmyard manure and ammonium sulphate enhances the utilization of added superphosphate by crops like wheat, cowpea, etc. Interaction and distributional pattern of microorganisms: The behaviour and distributional pattern of microorganisms depend on the nutrients available, temperature, moisture, gas content, pH, and depth of soil. Note # 15. Today the pasteurization process, widely used in fermentation indus­tries, is the contribution of Pasteur. Spores of yeasts are most abundant in the air spora before dawn, spores of Phytophthora infestans late in the morning and spores of Clado­sporium, Alternaria, and Ustilago in the afternoon. Aspergillus spp.) Although bacteria are more numerous than any other group of organisms, the biomass of the fungi is larger than that of bacteria and also the combined biomass of protoeoa, nematodes and other soil animals are quite different. 4.7 MICROBIOLOGY 4.7.1 Introduction Microbial communities represent a fundamen-tal part of aquatic ecosystems and are of great importance for the matter and energy flux (Kavka et al. It also includes the study of their distribution in nature, their relationship to each other and to other living organisms. In fresh water, the pro-fundal zone and benthic zone are largely populated by heterotrophic organisms. Synthetic processes of microorganisms also contribute some amount of complex organic nitrogen compounds. Journal covers all the aspects of Aquatic sciences (fresh waters, marine waters and marine life, etc.,). A portable, low-cost, and low-maintenance solar unit to disinfect unpotable water has been designed and tested. There is still a lot to understand about how the host resists invasions by microbial pathogen. Background. They are then allowed to dry in the shade. Medical microbiology deals with disease producing organisms in human beings whereas immunology deals with the defense the body puts up against the pathogens, the disease causing microorganisms, and the factors which explain resistance to disease. This sulphur is released from amino acids by enzymatic activity of many heterotrophic bacteria. In most agricultural soils sulphur is present in sufficient concentrations to meet the requirements of the soil population and crop plants. are dis­persed by air and may produce infection when inhaled. Pharmaceutical microbiology is the branch of microbiology that focuses on all aspects of pharmacy especially as it relates to the manufacture and quality control of pharmaceuticals such as drugs. h�bbd``b`z $g��, �i$��A�4R��b����X� B�7D( �P ��H�Ta`bd�c`0�?��� &~ Some of these condi­tions are: temperature, hydrostatic pressure, light, salinity, turbidity, pH, and in­organic and organic constituents. The denser particles settle rapidly but of lighter ones remain suspended per­manently. ecosystems : Communities of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water, and mineral soil), interacting as a system; linked together through nutrient cycles and energy flows. Save the syllabus for reference during the term. Zaccharias and Hans Janssen (a father-and-son team) ... industrial water system piping, natural aquatic systems, foods, and also on living tissue. Study of microorganisms has answered many vital questions like the role of micro­organisms in the formation of coal, petroleum, and utilization of raw materials (hydro­carbon;) for transformation into valuable chemicals. The quantity of phosphobacterin to be used, however, varies from the nature of seed to seed. Air borne fungal spores are responsible for pulmononary disease. Next to the production of ethyl alcohol is the production of alcoholic beverages—beer, wine, run, whisky, and gin. Trace elements (e.g., Zn, Cu, Co, etc.) It was he who discovered the typical bacilli responsible for the anthrax disease of cattle and this was the first time a bacterium had been proved to be the cause of an animal disease. Fungi are not only harmful but beneficial also. The most outstanding current development in applied microbiology is the ability to alter an organism’s genetic makeup which is commonly referred to as genetic engineering which area of scientific contribution holds great potential for production of drugs and vaccines, for improvement of agricultural crops, and various other areas. Some of the bacteria taking part in the above process are: Pseudomonas, Corynebacterium, and Flavobacterium. These spores are derived from moldy crains, straw, damp vegetation and compost heaps. NorCal Open Access Publications strategy is to provide 24/7 access to the scientific data freely for all our readers across the planet and will guarantee scientific community high data availability in … Microbiology is not a mere study of the structural diversity and classification of microbes, but encompasses the whole gamut of microbial life. Principle of Microbial Interaction: In a system of blue-green algae, Azotobacter and photosynthetic bacteria Rhodopseudomonas, the photosynthetic evolution of oxygen by the blue-green algae can provide an aerobic environment to Azotobacler. His series of observations led to the establishment of Koch’s postulates: (i) A specific organism can always be found in association with a given disease. i. Microorganisms and Principles of Biology: Microorganisms help understanding the various principles of biology as they consist of many characteristics which make them ideal for the investigation of important biological phenomena. They are used either to fix atmospheric nitrogen or to solubilize plant nutrients like phosphates or to otherwise stimulate plant growth through synthesis of growth promoting substances. Why mitochondria is called as the power house of the cell? The period from 1880 to 1900 was actually a golden time for microbiology when classical contributions were made leading to the establishment of microbiology as a science. It has also been demonstrated that total nitrogen fixed in the mixed culture of Azotobacter chroococcum, Rhodopseudomonas capsulatus, and Cylindrospermum muscicola is greater than in pure cultures of each organism as bccause the mutual association of Aztobacler and the photosynthetic bacteria Rhodofiseudomonas capsulatus results in pro­viding the energy source. Again the major part of the fungal flora occurs in the upper soil horizons where there is most organic matter. One of the more acceptable of these proposals suggests that life originated in the sea following- million years of chemical evolutionary process. phosphaticum. It includes microscopic plants, animals, bacteria, viruses and fungi and their behaviour, relation with other pH, temperature, nutrient available, oxygen supply, and moisture. Pasteur did not believe that animals could live in the absence of microorganisms. Freshwater: Fresh water is naturally occurring water on the Earth’s surface in ice sheets, ice caps, glaciers, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams. The bacterial growth on agar surface is to be scraped by adding water and the solution so obtained is to be sprinkled on the seeds spread in thin layer. To ensure that food is free of harmful microorganisms and is safe for human consumption, it must be carefully prepared, processed, and stored. Winter 2017 MB 399, Aquatic Microbiology (3 credits) MWF 2:00 to 2:50 PM Please carefully review the syllabus. Overview. The role of microbes in Industrial Production is studied here. In this course the bacteria can fix nitrogen and assimilate carbon dioxide. (iv) It is possible to recover the organism in pure culture from the experimentally infected animal. Rhodotorulla and other yeasts, and spores of the species of Apergillus, Penicillium, Mucor and other molds are commonly present. Many viruses including those of influenza, the common cold, measles, smallpox, etc. h�b```��,�����(���q�Q���ɠ��Z?���M ʋﹸ������\ܸ�������Dq ��@����B3�EBx��h';jo��#pC����s|s�偪V�i���0����H�10��Ҍ@�` H�- Microbiology Chapter 1- Scope of Microbiology. It also includes the study of their distribution in nature, their relationship to each … As we know, microbes improve the fertility of soil by fixing atmospheric nitrogen into nitrogen-compounds which are readily used by plants to synthesize protein and other complex organic nitrogenous compounds. iii. In the secretions of ears saprophytic acid-fast Mycobacterium smegmatis is common. Some of the genera of fungi taking part in the process are: Botryotrichum, Chaetomium, Humicola, Stachybotrys, and Stysanus. SOJ … They have been remarkably successful in exploiting the useful microorganisms and combating the harmful ones and have also successfully solved intricate problems of biochemistry and genetics using microorganisms as tool for their study. Development of new isolation techniques may lead to the discovery of new micro-organisms that may open new door in industrial microbiology and environmental control. Microbiologists can also specialize in certain areas of microbiology, such as clinical microbiology, environmental microbiology, applied microbiology, or food microbiology. These materials are attacked by fungi, and to a less extent by bacteria, causing econo­mic loss. 374 0 obj <>/Filter/FlateDecode/ID[<1DB6E0F65B8F2642823E491ECC29D18C><11B2AA9558DC70479D57D47F8ADC2389>]/Index[357 45]/Info 356 0 R/Length 85/Prev 52566/Root 358 0 R/Size 402/Type/XRef/W[1 2 1]>>stream Microbes are used as gene carriers to deliver specific genes to function in a different environment. For example, by the application of the recombinant DNA method new strains of bacteria may be developed which are capable of synthesizing a wide variety of biological and chemical substances not yet producible on a industrial scale. These proteolytic enzymes are produced by Clostridium histolyticum and C. sporogenes and species of the genera. Such proteins are used to produce a milk substitute for calves, thus releasing more cow’s milk for human consumption. They are responsible for various diseases (pulmonary or otherwise) of humans. Microbiologists may specialize in the study of different groups of microorganisms. Whereas, in marine water, the area between the upper strata and the area just above the sea floor is relatively barren, a vast microbiological oceanic desert region. About 1000 viable bacterial cells per seed is to be attained at the time of treating the seed. (a) Decomposition of organic matter, transformations in the soil and maintenance of soil fertility balance; (b) Improvement of soil fertility, reclamation of barren soil and check soil erosion; and. Microbiology of Soil 7. Mineralization of organic carbon, nitrogen, phosphorus and sulphur via respective cyclic alterations by soil microorganisms makes these elements available for reuse by plants and other organisms. Although green plants and algae are the most important agents of assimilation of carbon dioxide present in the atmosphere or dissolved in water, bacteria are also capable of synthesizing organic matter from inorgaic carbon through Carbon Cycle. The remainder is incorporated into humus—the dark-coloured amorphous organic material which is important for soil fertility. Besides these, the microorganisms also convert atmospheric molecular nitrogen into ammonia by a process known as nitrogen fixation. These are originally introduced from soil contamination, but become established as a resident population in tanks and pipelines. Ecology and environment: Bacteria are primary decomposers – recycle nutrients back into the environment (sewage treatment plants) 6. Organic matters derived from microorganisms accumulated in mud deposits of the ocean floor were buried in course of time by sedimentary action and were gradually converted into oil and gas. The soil micro- fauna was neglected for even longer and only recently attention has been drawn in the” soil algae. The organic materials are always associated with soil organisms. Biological Oxygen Demand (BOD) is a measure of the oxygen used by microorganisms to decompose this waste. Cultural studies however, permit identification of the isolates though not very satisfactory for fungi. Addition of organic matter to a soil stimulates the growth of fungal flora in soil in the same way as it does the zymogenous bacterial population. Majority of filamentous fungi are aerobes and their mycelium is interwoven among the soil particles and it binds these together, thus improving the texture of soil. It is essential to treat biological wastes by chemicals or by microorganisms to re­move disease-producing microorganisms which cause offensive odour. But today it is realized that every microorganism has its own industrial importance. The Journal of Aquatic Food Product Technology publishes research papers, short communications, and review articles concerning the application of science and technology and biotechnology to all aspects of research, innovation, production, and distribution of food products originating from the marine and freshwater bodies of the world. The tears secreted on the conjunctiva of the eyes contain the enzyme lysozyme, which attacks bacterial cell walls causing lysis, and this keeps the number of organisms in this site at a low level. Our mission is to provide an online platform to help students to share notes in Biology. The emergence of a series of new waterborne and food-borne pathogens that posed a threat to human and animal health. How protective vaccination helps in combating the diseases? The arms race between bacteria and their competitors has produced an astounding variety of conflict systems that are shared via horizontal gene transfer across bacterial populations. It is generally true, however, that more the microorganisms there are in the soil, the more productive it is. Again the name of Joseph Lister (1878) is associated with the concept on pure culture technique. This includes the study of microorganisms causing food spoilage; as well as, pathogens that may cause disease especially if food is improperly cooked or stored. Microbial mining may provide a viable alternative in some cases such as copper and uranium. Proteus, Pseudomonas, and Bacillus; and many fungi and actinomycetes. %%EOF Branches 5. COLONY-COUNTER: - for counting colonies. This branch deals with the pathogenic microbes—their life-cycle, physiology, genetics, reproduction, etc., Many of the microbes also provide remedies for microbial diseases. It contains important information on course requirements, grading, etc. Many of them are pathogenic, bad odour and taste producing. The sugar or gur solu­tion is boiled and cooled before the culture is sprinkled on the seeds and the seeds are thoroughly mixed with bacterial suspension so as to have uniform coating of bacteria. Besides these, the distribution of microorganisms varies according to the depth of water. The wide-scale application of herbicides and pesticides for improving crop yield produces certain side effects which need careful consideration and fruitful solution. The more microorganisms there are in the soil, the more productive it is. Again some microorganisms oxidize and others reduce various sulphur compounds. Introduction to Microbiology, History & scope Microbiology: - In the broadest sense, microbiology is the study of all organisms that are invisible to the nak… Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Generally there is decrease in numbers with depth. occur. Again with a high bacterial response the R/S ratio for protozoa is also high. Ground water is subterranean water that occurs in the soil or rock-containing materials. The commercially beneficial activities of a large number of bacteria, yeasts, molds, and algae are being exploited, or deserve to be exploited to obtain valuable products. The production of fermented beverages and vinegar, and the baking of bread are all traditional processes which have come down to use from time immemorial. Some portion of carbon contained organic residues is incorporated in microbial tissues which themselves will eventually be decom­posed. When inhaled there is development of aspergillosis of lung. Studied in this branch are the immune responses in organisms. For convenience, how do complex cellular structures develop and how do cells communicate with one another and respond to the environment? The scope of Microbiology is huge because of the involvement of microbiology in various fields such as Pharmacy, Medicine, clinical research, agriculture, dairy industry, water industry, nanotechnology & chemical technology. He also founded that fermentation of fruits and grains, resulting in alcohol, was brought about by microbes. Thus it is apparent that microorganisms perform numerous and essential functions that contribute to the productivity of soil. This is one of the most important branches of microbiology. Such equi­librium may be disbalanced when the host resistance is lowered and the normal flora assumes a pathogenic role. Aquatic microbiological studies are diverse and inherently interdisciplinary. Again a relationship between organisms in which one partner receives benefit, the other is not affected. Finally Louis Pasteur (1822-1895) through his series of experiments proved his germ theory by establishing the fact that different germs came into the world from their parent germs and germs induce various diseases which was suggested by earlier workers. These substances when deposited in soil cause destruction of soil microorganisms, they run off with rainwater and thereby also cause pollution to streams and rivers and as such affect aquatic flora and fauna. Environmental Microbiology is devoted to the advancement of our understanding of microbial interactions and microbial processes in the environment, and publishes original research reporting significant advances in or relating to this subject.. Brief Reports, documenting a single important finding, are published in our sister journal Environmental Microbiology Reports. Industrial microbiology may be grouped in the following manner: One of the oldest and largest microbial industries is the production of ethyl alcohol from carbohydrate materials by fermen­tation process. It is con­cerned with the form, structure, metabolism, growth, reproduction and identifica­tion of microorganisms. Industrial Microbiology 6. iv. Most actinomycetes are soil inhabitants. History of Microbiology 3. Scope. Since both the problems of small size and the methods of study and since unrela­ted microorganisms frequently occupy the same habitat and thus influence each other, it is convenient to study them within the same discipline, i.e., Microbiology. Mention may be made of some of the contributors and their contributions in microbiology and mole­cular biology during the period from 1944 to 1975: Avery and associates (1944)—DNA carries genetic information in pneumococcus; Fritzhipman and Hanskrebs (1953) — physiology and metabolism of living cells; Joshua Lederberg, George Beadle, and Edward Tatum (1958)—genera in bacteria and their recombination. Microbiology can be also classified based on taxonomy, in the cases of bacteriology, mycology, protozoology, and phycology. The benefits derived by the associated organisms are extremely variable. Often after rain near the ground level—wet-air-spora is rich in basidiospores and ascospores which is replaced by dry air spora which consists of pollen grains and dry spores of powdery mildews, Alternaria, smuts and rusts. The organic carbon compounds so formed are deposited in the soil due to annual litter fall and death of different groups of plants and animals. No information on the species of orga­nisms is obtained by these methods. The hydrocarbon content may be lowered by the attack of species of Actinomyces, Serratia, and Pseudomonas-, and Penicillium and Aspergillus. (iii) The pure culture will produce the disease when inoculated into a susceptible animal. The journal covers all the significant areas of Aquatic Microbiology is devoted to advancing the study of microbes in aqueous environments, with a focus on freshwater, estuarine and oceanic ecosystems. Most of the microorganisms involved in the carbon cycle in terrestrial environments are heterotrophic. Of the environ­mental conditions, moisture is particularly important as in dry conditions the attack will be slow. Deals with the study of autotrophic eukaryotic organisms. 3.0 REFERENCE: Aseptic Technique for Microbiological Testing. There may be further specialization in some aspects of above groups of microorga­nisms; for example, bacterial genetics, bacterial cytology, algal physiology, medical mycology, etc. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. An interesting aspect is the rumen (first chamber of stomach of herbivorous animals) symbiosis of microorganisms. Air spora constituting fungal spores near ground level display a diurnal periodicity. ); various human diseases (tuberculosis, leprosy, tetanus, etc. The phos­phobacterin solution should be then sprinkled on seeds before sowing. The carbon dioxide produced during fermentation is responsible for the rising of the dough. Besides penicillin, tetracyclines are produced by using Streptomyces rimosus and S. aureofacieus. A general account of the distributional pattern of the microorganisms is given below: i. These may con­taminate food and moist perishable organic materials, such as leather, and inhalation may cause respiratory infections of man and animals and allergic reactions, such as asthma. Disclaimer Copyright, Share Your Knowledge The growth of soil algae affects the surface soil by depletion of some nutrients. The Microbiology of Drinking Water (2012) - Part 7 - Methods for the enumeration of heterotrophic bacteria Methods for the Examination of Waters and Associated Materials This booklet contains two methods for the enumeration of Aquatic microbiology Aquatic microbiology deals with study of microbes of aquatic system such as fresh or salt water systems. By the dry sand culture method dried algae are obtained which remain viable more than two years. Recent advances have been made in the techniques for the isolation and joining of unlike pieces of DNA molecules so that biologically active recombinant DNA molecules can be made in vitro. The dry sweepings of floors, the dusting of objects, shaking clothes, making beds, movement of people and droughts can break up the original substrates into finely divided particles or disturb settled dust and cause it to become air borne. There is no normal flora of the trachea and bronchi. (vii) The microbiology of tomorrow has to solve a variety of fundamental questions in biology. After reading this article you will have a basic idea about:- 1. Some of the common examples are: fungi (Termitomycetes spp) and termites; flagellate (Hypermastigina and Polymastigina) as weir as bacteria and rickettsia’s with termites; mycoflora (Saccharomyces spp. We can study the metabolic patterns of microorganisms and other life processes at different stages of their growth and reproduction very easily in comparison to higher organisms. Isolation experiments suggest that in general, species of Mucor, Penioillum, Trichoderma, and Aspergillus predominate and those of Rhizopus, Zygerhynchus, Fusarium, Cephalosporium, Cladosporium, and Verticillium are also often present in the soil. Air borne microorganisms constitute mainly viruses (influenza, measles, etc. The source of raw material may be molasses, sugar beets, grapes, etc. Since crude oil is contaminated with wine from the oil beds and water is invariably present in the storage tanks from condensation, in transport and storage crude oil may be attacked by Actinomyces sp., Mycobacterium sp., Pseudomonas aeruginosa, and Desulfovibrio sp. Strains of Saccharomyces cerevisiae are used for fermentation. An investigation was carried out to measure the heat susceptibility of opportunistic mycobacteria frequently isolated from domestic water supply systems. Space Microbiology and Others. These bacteria and fungi bring about solubilisation by the production of organic acids. Many microbes produce industrial alcohols and acids as a part of their metabolism. The poioneer workers of the late nineteenth century in this line are: Beijerinck and Winogradsky. During application of blue-green algal fertilizer, algal inoculum may be inoculated in small algal beds in the field sprinkled with lime to promote the growth of inoculum. Spores which can tolerate dehydration will survive longer than vege­tative cells. Microbial fertilizers contain primarily active strains of microorganisms (blue-green algae, bacteria), mainly bacteria in sufficient numbers. In the benthos two distinct life forms are found, one attached and non-motile, the other unattached and capable of horizontal and vertical move­ments. v. The soil fauna contains numerous protozoa and representative of metazoa. Of all these organisms, yeasts are better suited for single-cell protein extraction. Members are generally called algae. The volume of moisture and the nature of microorganisms in each stage are extremely variable. This is accomplished by microorganisms capable of converting protein to smaller units—peptides with the help of enzymes—proteinases. The concept of origin of animals spontaneously from the soil, plants, or other unlike animals spon­sored by Aristotle (384-322 B.C.) Their numbers increase with the warmth of the climate and decrease with depth of the soil. Soil, water and air which contain living organisms are collectively known as biosphere. - Its subjects are viruses, bacteria, many algae and fungi, and protozoa. Certain groups of microorganisms (bacteria and viruses) are put to large scale cultivation for the commercial production of vaccines. The journal of environmental microbiology page provides an introduction to the journal. It is produced due to interaction of parental material (rock itself), climate, age, and growth and interaction of microorganisms. Examples of bacteria involved in the sulphur cycle in various ways are: species of the genus Desulfotomaculum; purple and green sulphur bacteria Chromatium and Chlorobium; nonsulphur purple bacteria Rhodospirillum, Rhodopseudomonas and Rhodomicrobium. Only the microscopic algae are studied as a part of microbiology. Again the normal flora of the upper respiratory tract is represented predominantly by Streptococcus salivatius, S. pyogenes, Neisseria pharyngis, and Haemophilus influenzae. of beehives; wood-inhabiting insects (bark-boring beetles) and ambrosia fungus (Ceratocystis ulmi). But, what would be the most promising areas for future microbiological research?
