K) Veterinary Microbiology
- Scope of Microbiology in Veterinary Microbiology—This subdiscipline deals with the harmful effects of disease agents on domestic livestock and poultry. The spread and control of such pathogens are of major concern.
- The veterinary microbiologists are getting good jobs now in the dairy industry and big poultry farms.
- They may also establish their own small livestock or poultry units, as they are well-informed about the biology and microbiology of these animals. The government is also offering good subsidies to continue the achievement of the “White Revolution.”
L) Aeromicrobiology
- It deals with the study of the atmospheric environment, which includes pollutants as well as bacteria, bacterial spores, fungal spores, viruses, etc.
- As such it is the job of Aeromicrobiologists to study the microbial content of air present in domestic living areas, pharmaceutical units, food-processing or dairy plants, etc.
- To prevent nosocomial infections in hospitals and plant diseases in farms, it is necessary to take the survey of aerial flora of hospitals and farms, respectively.
M) Exomicrobiology
- It deals with the studies on exploration for life in outer space.
- Scope of Microbiology in Exomicrobiology is the scope of microbiology. Exo-microbiologists, or space microbiologists, had to find out how microbes can be useful at various levels in space exploration studies.
- For example, microbes can be used as indicators to test the effects of weightlessness, acceleration, radiation, a completely artificial atmosphere, and the many new experiences human beings may have in space travel.
- Studies are also carried out to detect the presence of microorganisms on the Moon, Mars, and Venus. These types of studies will help in solving many mysteries of outerspace areas.
- So many microbiologists have good opportunities to work in multifaceted outer space programs. NASA is the biggest institute where active studies on exomicrobiology are going on. In India, the Centre for Cellular and Molecular Biology [CCMB] at Hyderabad is involved in such studies.
N) Aquatic Microbiology
- It deals with the study of microorganisms and their activities in fresh, estuarine, and marine waters.
- Aquatic microorganisms and their activities are of great importance in many ways. They may affect the health of human and other animal life; they occupy a key position in the food chain by providing rich nourishment for the next higher level of aquatic life, and they play an instrumental role in the recycling of elements (i.e., mineralization).
- Aquatic microbiology has emerged as one of the major fields of applied microbiology. Urbanization and, consequently, the growing demand for water by communities; the importance of natural water as a major food source; the offshore exploration for oil and minerals; and the availability of novel drugs and enzymes from marine microorganisms have attracted the attention of so many dominant rulers all over the world.
- The microbiologists have the challenging opportunities for exploring the isolation of microorganisms producing valuable drugs, antibiotics, enzymes, and vitamins and also have ample opportunities to cultivate “seaweed” for the source of biomass to make delicious fermented foods such as “nori,” “shoyu,” etc.
O) Geochemical Microbiology (Bio-Extractive Metallurgy)
- It deals with the applied areas such as coal, mineral, and natural gas formations. It also highlights the recovery of minerals from low-grade ores with the help of microorganisms (microbial ore leaching).
- A separate branch known as “coal biotechnology” has emerged due to roles played by acid bacteria in coal mining.
- This is a very interesting and thrilling field where microbiologists can utilize their knowledge in extracting important as well as precious metals from mines. More and more microorganisms are now available, which can leach a variety of metals at very low cost with simple technology. Coal biotechnology is still one more promising field for microbiologists. The government-undertaking mining corporations as well as some big private mining companies are now offering lucrative jobs as metallurgic microbiologists.
P) Petroleum Microbiology
- Microorganisms are associated with petroleum in its formation, exploration, its recovery by drilling, the enhancement of recovery, its decomposition, and its utilization.
- Petroleum microbiology involves such studies, which require an interdisciplinary approach by taking cooperation from chemists, engineers, oil technologists, and geophysicists.
- This is also a very interesting and thrilling field for microbiologists, as microbiology is involved at each and every step in petroleum industries, especially in microbially enhanced oil recovery. Even microbes are useful in removing oil spills and thereby reducing the problems of oil pollution, evoking images of impending “ecological dooms” and helping in the survival of sea life. Microbiologists have achieved the skill of “bioremediation” to solve the problems of oil pollution through recombinant DNA technology. “Super hug” (genetically engineered Pseudomonas putida) is the best example of bioremediation conceptualized by Dr. Anand Chakravarty.
