Introduction Chewing gum in various forms has been around since ancient times. The Greeks chewed sap from the mastic tree, called mastiche. On the other side of the world, the ancient Mayans favored the sap of the sapodilla tree (called tsiclte).
Bioremediation is a waste management technique that involves the use of organisms to remove or neutralize pollutants from a contaminated site.ioremediation may occur on its own (natural attenuation or intrinsic bioremediation) or may only effectively occur through the addition of fertilizers, oxygen, etc., that help encourage the growth of the pollution-eating microbes within the medium (biostimulation).
The first type of bioremediation is biostimulation; nutrients in a gas or liquid form are added to soil or water where there is a need to remove contaminants. The bacteria are already there they are just stimulated to encourage growth and activity.Essencially the he bacteria turn the harmful substances in to CO2.io augmentation. The second type of bioremediation is bio augmentation, where microorganisms are added to the soil to help remove contaminants. It is more commonly used in contaminants in the original site, and is more successful.
