To Clear Pollution

* Dehalococcoides as known as bacteria can be used to clean up toxins and pollution.

* Bacteria can remove chlorine atoms

from molecules and leave less-toxic

compounds behind in toxic waste.

*In some places the bacteria works and in some it doesn't work as well and nobody knows why.

*To improve the conditions of the bacteria starting and stopping scientists put Vitamin B-12 inside the bacteria.

* Without bacteria there would be tons of dead material all over the earth, deeper than we are all tall.

*An organism called Saprophyte helps maintain the nature balance.

* The Saprophytic bacteria help recycle nutrients. One type of bioremediation uses bacteria to break down pollutants and waste into simpler harmless compounds.
