Bacteria can be friendly?

A  ship  for some reason has a crack and there's a huge oil spill in the middle of the ocean . Harmless fish, plants and animals become sick and eventually die because  of the toxic chemicals which now contaminate the waters and their environment . Sea otters for example die from hypothermia because their oil-soaked furr can no longer keep them warm . At least their is a solution! A biotechnology called Bio-remediation is a process that microorganisms or their enzymes turn the contaminated environment  back into its non-contaminated condition. Bacteria attacks certain contaminants, degrades them and turns them back into nontoxic compounds.  Some bio-remediation types are:

• Phytoremediation
• Mycormediation 
• Bacterial Bioremediation
