Transcript

  • 1. Aquatic Microbiology Asar Khan (M.Sc Zoology) AWKUM Buner
  • 2.  Study of microorganisms and their communities in water environment.
  • 3.  the study of microorganisms in potable or drinking water.  No pathogens  No chemicals  No taste  No odor  No color  No harm to human health
  • 4. (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.
  • 5. (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.
  • 6. 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 
  • 7.     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:
  • 8.  lakes, rivers , streams, seas , rain, snow & Groundwater.
  • 9.  Bacteria  Virus  Protozoa  Helmiths  Spirochete  Rickettsia  Algae
