KINETIC APPROACH OF BIOREMEDIATION CAPABILITY OF INDIGENOUS BACTERIA FOR ORGANOPHOSPHATICPESTICIDES

摘要

Research on Bioremediation of organophosphorus pesticides (Malathion and Profenofos) is one of the effort's approach to the application of science and technology in the remediation of the waters of Lake Rawa Pening. Pesticides is one of the pollutantsto note; given the nature of the pesticide that is difficult to unravel, so exposure to pesticides on aquatic Rawa Pening in long periods of time can cause disruption of ecosystems that allow bio-accumulation and bio-magnifications. Bioremediation of pesticide with indigenous bacteria make a most effective remediation technology, with the discovery of bacterial strains that have the capability of degradation of pesticides (Malathion and Profenofos) is Oceanobacillus iheyenis, Exiquobacterium profundumand Bacillus formis are new efforts in the management of the pollution caused by the organophosphorus pesticides (Malathion and Profenofos). This is because the bacterial strains successfully identified a bacteria that degrade organic compounds in the phosphate group, in this case is the organophosphorus pesticide Malathion and Profenofos. This research was conducted to determine the ability of indigenous bacterial degradation of Malathion and Profenofos by using the Spectrophotometry method. Based on the results of research that the bacterium has the ability to test degradation perfectly as follows: 1. Bacterial Exiqoubacterium profundum best capability on substrate Malathion (laboratory scale with 72 hours incubation) and the bacteria Bacillus formishas the ability the best substrate degradation of Profenofos (laboratory scale with 72 hours incubation) 2. Consortium Exiquobacterium profundum/Oceanobacillus iheyenis have the ability of degradation best on Malathion (laboratory scale and scale applications with 168 hours incubation) and consortium of bacteria Bacillus formis I Exiquobacterium profundum has the best substrate degradation abilities of profenofos (laboratory scale and scale applications with 168 hours incubation),
