INTRODUCTION Study of microorganisms and their communities
in water environment.
WATER MICROBIOLOGY the study of microorganisms in potable
or drinking water.
No pathogens No chemicals No taste No odor No color No harm to human health
AQUATIC ENVIRONMENTS(1) Marine Ecosystem plants and animals interact with the
chemical and physical features of the environment.
aquatic areas of life, They can be oceans, ponds , marshes, lagoons, or any area with water that supports life.
(2) Fresh Water Ecosystem
factors, including temperature , light penetration, and vegetation.
Only 3% of the world's
99% of this is either frozen in glaciers and pack ice or is buried in aquifers.
The remainder is found in lakes, ponds, rivers, and streams.
SCOPE wide and includes the habitats like Planktons live in water column incapable of swimming crucial source of food to
large aquatic organisms, such as fish and whales.
Benthos community of organisms which live on, in,
or near the seabed also used in freshwater biology food sources for the benthos are algae Organisms such as sea stars, oysters,clams,
sea cucumbers, brittle stars
Microbial mats a multi-layered sheet of microorganisms,
mainly bacteria and archaea. Temp from –40°C to 120°C industrial uses for water treatment
and for cleaning up pollution.
Biofilm group of microorganisms in which
cells stick to each other on a surface. 5 stages of development
Initial attachment: Irreversible attachment: Maturation I: Maturation II: Dispersion:
FOUND IN
lakes, rivers , streams, seas , rain, snow &
Groundwater.
NUTRIENT CYCLES IN AQUATIC ENVIRONMENTS
