Bioremediation of DDT Essay
This chemicals impact has given need to researches to discover a new way to remediate this toxin within the environment. Microorganisms and fungi have been discovered capable of breaking down DDT as well as its byproducts (DDD and DDE) that are just as dangerous for the environment. Pseudoxanthomonas species was a strain of organisms that demonstrated the most efficiency at remediating DDT out of soil. The microbe was then cultured in the lab and tested within many different environments to find optimum conditions. The experiment tested the effects of acidity, addition of compounds in soil, temperature, how much air was in the soil as well as different concentrations of the chemical. Under the addition of carbon as a nutrient the organism was highly effective removing 95% of DDT at a concentration of 20mg per liter of soil (9). Another bio-remediate is Gleophyllum traberum, a brown-rot fungus (2). The study concluded that the fungi can be used without further supplements in the soil, although the additive of an iron cation increased decomposition (2).
These findings are
