Bioremediation and biodegradation

  1. 1. BIOTECHNOLOGY<br />BIOREMEDIATIONANDBIODEGRADATION<br /> By,<br />R.HARISH KUMAR<br />JAYA COLLEGE OF ARTS AND SCIENCE<br />THIRUNINRAVUR.<br />
  2. 2. Strategies for clean environment<br />bioremediation<br />biodegradation<br />
  3. 3. Bioremediation<br /><ul><li> Bioremediation is a process of removing or degrading the toxic pollutant from the environment by using microorganism .
  4. 4. commonly used micro organisms are,</li></ul>Pseudomonas,Flavobacterium,Arthrobacter, and Azotobacter<br /><ul><li> Bioremediation focuses on different sources they are called as different names.</li></ul>plant------------- phytoremediation<br />fungi------------- mycoremediation<br />Biodegradation<br /><ul><li>Degradation or Transformation of a substance into new compounds through biochemical reactions or the actions of microorganisms such as bacteria.</li></li></ul><li>BIODEGRADATION<br />
  5. 5. Examples :<br />Psychrophiles----- Arthrobactersp., Psychrobacter sp., Pseudomonas<br />Mesophiles--------E-coli bacteria, Staphyloccusaureus,Proteusvulgaris<br />Thermophiles-----Thermusaquaticus ,Thermococcuslitoralis.<br />
  6. 6. BIOREACTOR<br />COMPOSTING<br />iNTRINSIC<br />engineered<br />LANDFaRMING<br />BIOREMEDIATION<br />In-situ<br />Ex-situ<br />
  7. 7. Recent approaches<br />bioremediation<br /><ul><li>Earth warms can degrade heavy metals</li></li></ul><li><ul><li>Bacteria from the deep:</li></ul>Brachybacterium spMn32<br />
  8. 8. <ul><li>Nemesis for oil spills</li></ul>Oleophillic bacteria<br />
  9. 9. GMOs<br />Genetically modified<br />organism<br />
  10. 10. GMOs<br />Genetically modified<br />organism<br />The genetically engineered micro organism (GEMs)enhance the ability of degrading the contaminants. It is also said to be as a “bioaugmentation”<br />
  11. 11. Construction of superbug<br />
  12. 12. The bacterium Deinococcusradiodurans(the most radioresistant organism known) has been modified to consume and digest toluene and ionic mercury from highly radioactive nuclear waste.<br />Strains of Deinococcusradiodurans<br />
