ENVIRONMENTAL MICROBIOLOGY

• Introduction to Environmental Microbiology
• Types of microorganism on the basis of nutrition
• Factors affecting  microbial growth(Temperature, pH, Oxygen concentration, Pressure and radiation)
• Microbial growth curve (Lag phase, acceleration phase , exponential phase, deceleration phase, stationary phase, death phase)
• Distribution of microorganisms in environment

• Interaction among the microbial populations(Positive and negative interactions)

                              -Mutualism

                              -Parasitism

                              -Amensalism

                              -Competition

                              -Predation

                              -Protocorporation

                              - Commensalism

• Mycorrhizae-Ectomycorrhizae and Endomycorrhizae

• Microbial habitat in the aquatic environment

-Planktonic environment

-Benthic habitat

-Microbial mats

-Biofilms

• Microbial characteristics of fresh and marine water

• Soil habitat (Lithosphere)
• Microbial biogeochemical cycling

-Carbon cycle

-Nitrogen cycle

-Sulphur cycle

-Phosphorus

• Rhizosphere

• Bioremediation
• Phytoremediation
• Biodeterioration- wood deterioration,Paper-pulp,Rubber
