EV4102 Environmental Microbiology Syllabus:
EV4102 Environmental Microbiology Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To provide a basic understanding on microbiology relevant to environmental engineering for candidates.
To gain knowledge on morphology, behaviour and biochemistry of bacteria, fungi, protozoa, viruses, and algae .
To understand the microbiology of wastewater, sewage sludge and solid waste treatment processes. And to understand the aspects of nutrient removal and the transmission of disease causing organisms .
To have an exposure to toxicology due to industrial products and byproducts.
UNIT I FUNDAMENTALS OF MICROBIOLOGY
Classification of microorganisms – prokaryotic, eukaryotic, cell structure, characteristics, importance, introduction to water, soil and air borne pathogens and Parasites and their effects on human, animal and plant health, transmission of pathogens, transmissible diseases – bacterial, viral, protozoan, and helminths parasites, concentration and detection of virus. Control of microorganisms preservation of microorganisms, DNA, RNA, replication, recombinant DNA technology, their potential applications and intellectual property rights.
UNIT II MICROBIAL DIVERSITY AND NUTRIENT TURNOVER
Distribution of microorganisms in different environments – diversity of microorganisms – fresh and marine, terrestrial – microbes in surface soil, air – outdoor and Indoor, aerosols, bio safety in laboratory – extreme environment – archae bacteria – occurrence in water supplies – problems and control. biogeochemical cycles-nitrogen, carbon, phosphorus, sulphur – Role of Microorganism in nutrient cycle.
UNIT III METABOLISM OF MICROORGANISMS
Nutrition and metabolism in microorganisms, growth phases, carbohydrate, protein, lipid metabolism – respiration, aerobic and anaerobic-fermentation, glycolysis, Kreb’s cycle, hexose monophosphate pathway, electron transport system, oxidative phosphorylation, environmental factors, enzymes, bioenergetics, disruption in metabolism and disease. biodegradation of organic pollutants
UNIT IV MICROBIOLOGY OF WASTEWATER TREATMENT SYSTEMS
Microbiology of biological treatment processes – aerobic and anaerobic, α-oxidation, β-oxidation, nitrification and denitrification, eutrophication. nutrients removal – BOD, nitrogen, phosphate. microbiology of sewage sludge – indicator organisms of water – coliforms – total coliforms, E-coli, streptococcus, clostridium, Bioleaching
UNIT V TOXICOLOGY
Ecotoxicology – toxicants and toxicity, factors influencing toxicity. Effects – acute, chronic, test organisms – toxicity testing-lab and field testing methods, bioconcentration – Bioaccumulation, biomagnification, bioassay, biomonitoring.
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Explain the basic importance and functional elements of environmental microbiology including the potential applications in the environment and intellectual property rights.
CO2 Understand and describe the type of microorganisms in the environment, their importance in water supplies and the role of microorganisms in the cycling of nutrients in an ecosystem.
CO3 Understand the metabolic processes on carbohydrates, protein and lipids, importance of enzymes, production of energy and the various additional metabolic processes.
CO4 Select and apply appropriate methods for assessing the water, air and soil borne pathogens, their health implications, and importance of microbes in aerobic and anaerobic cycles and deterioration of water bodies.
CO5 Conduct testing and research on toxicology, understand the importance of test organisms, environmental applications such as biomagnifications, biomonitoring and in developing risk based standards.
