Microbial Ecology
To enable students to- • To understand aero microbiology and aquatic microbiology.. • To understand soil structure, properties and microbial interactions. • To learn about Environmental sample collection and processing • To learn about microbial life in extreme environments. • To study techniques used in microbial ecology.
Aero microbiology: Aerosols, Pathways (Launching, Transport and Deposition), Microbial survival in air. Airborne pathogens and toxicants. Biosafety in Laboratory Aquatic microbiology: Planktonic environment, Benthic habitat, Microbial mats. Biofilms: Formation, Morphology, Physiology, beneficial and detrimental proprties, Physical, chemical and microbiolgical characteristics of rivers, lakes and oceans.
Physicochemical characteristics: Solid phase(Particles texture and Profile),Orgaic matter(Humus),Soil pH. Soil atmosphere, microbal environment (Biotic and Abiotic Stresses). Soil microorganisms: Bacteria, Actinomycetes, Fungi, Algae, Protozoa. Microbial interactions: Symbiosis, Mutualism, Commensalism, competition, amensalism, synergism, parasitism, predation. Microbial transformation: P, S, N, Hg.
Sampling devices for collection of bioaerosols (impingement, impaction, centrifugation, filtrations and depositions Soil and sediments-sampling strategies and methods for surface soil and subsurface, sample processing and storage. Water- sampling strategies and methods for water, processing of water samples for virus analysis, detection of bacteria, protozoan parasites, detection of microorganisms on fomites.
Acidophilic, alkalophilic, thermophilic, barophilic and osmophilic microorganisms- mechanisms of adaptation. Halophiles- membrane variation, electron transport. Applications of thermophiles and extrempohiles
Unculturable and culturable bacteria-conventional and molecular methods of studying microbial diversity Culture methods- for enumeration of bacteria, culture methods for fungi, algae, cyanobacteria. Cell culture based methods for detection of viruses. physiological methods including measurement of microbial activity, carbon respiration, use of radio labeled tracers, Adenylate energy charge .enzyme assays (dehydrogenase and esterase assay)
