  • Strategies for clean environment
    bioremediation
    biodegradation
  • Bioremediation
    • Bioremediation is a process of removing or degrading the toxic pollutant from the environment by using microorganism .
    • commonly used micro organisms are,
    Pseudomonas,Flavobacterium,Arthrobacter, and Azotobacter
    • Bioremediation focuses on different sources they are called as different names.
    plant------------- phytoremediation
    fungi------------- mycoremediation
    Biodegradation
    • Degradation or Transformation of a substance into new compounds through biochemical reactions or the actions of microorganisms such as bacteria.
  • BIODEGRADATION
  • Examples :
    Psychrophiles----- Arthrobactersp., Psychrobacter sp., Pseudomonas
    Mesophiles--------E-coli bacteria, Staphyloccusaureus,Proteusvulgaris
    Thermophiles-----Thermusaquaticus ,Thermococcuslitoralis.

    LANDFaRMING
    BIOREMEDIATION
    In-situ
    Ex-situ
  • Recent approaches
    bioremediation
    • Earth warms can degrade heavy metals
    • Bacteria from the deep:
    Brachybacterium spMn32
    • Nemesis for oil spills
    Oleophillic bacteria
  • GMOs
    Genetically modified
    organism
  • GMOs
    Genetically modified
    organism
    The genetically engineered micro organism (GEMs)enhance the ability of degrading the contaminants. It is also said to be as a “bioaugmentation”
  • Construction of superbug
  • The bacterium Deinococcusradiodurans(the most radioresistant organism known) has been modified to consume and digest toluene and ionic mercury from highly radioactive nuclear waste.
