BIOLOGY and BIOTECHNOLOGY

Biology ---- branch of science concerned with living thing Biotechnology ---- technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use

Plants, animals, birds, bacteria, fungus Microorganisms ---- easy to study, work as they have a simple and comparatively smaller genetic make up

  • April 20, 2010
  • BP, a leader in deep water oil drilling efforts
  • Triggered --- environmental disaster --- a gas release and subsequent explosion
  • ccurred on the Deepwater Horizon oil rig
  • Dumped an estimated 205 million gallons of oil into the Gulf of Mexico
  • Several studies suggest that microbes successfully consumed part of the oil
  • Alcanivorax borkumensis was added to the waters to speed digestion

Brown mustard, Sunflower, Bladder campion, Barley, Pumpkin, Red clover, Poplars, Pine, tobacco, water hyacinth Plants can help bind, extract, transform and clean up many kinds of pollution including metals, pesticides, chlorinated solvents, polychlorinated biphenyls (PCBs), explosives, radionuclides and petroleum hydrocarbons Plants clean up these forms of pollution as far down as their roots can grow Plants also help prevent wind and rain from carrying pollution away from the site to other areas.
