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).
Types of bioremediation Microbial bioremediation: Bioremediation can occur either naturally, or by the use of bioaugmentation (whole cell introduction) or Biostimulation approaches (use of nutrients or conditions to stimulate the native microbial community).ther extracellular enzymes used in bioremediation: Case studies Bioremediation of Textile Effluent using Enzymes Enzymes can act on specific recalcitrant pollutants to remove them by precipitation or transformation to other products.
