摘要：Leachate treatment containing methyl mercury (CH3Hg+ ) can be done by using biodegradation method.Bacteria used in methyl mercury biodegradation of the bacteria Empedobacter brevis.This study aims to examine the ability of bacteria in degrading methyl mercury in leachate and determine the value of µmax and Ks.The degradation process is done with variation of inoculum concentration and incubation time aerobically.The parameters analyzed were the decrease of methyl mercury content in the biodegradation process.The results showed that biodegradation of methyl mercury by the bacterium Empedobacter brevis at 15% inoculum concentration was the highest decrease efficiency of 81%.The values of µmax and Ks in the bacterium Empedobacter brevis were 0.994 per hour with a substrate concentration of 1.588 mg /l.The reduction of methylmercury biodegradation process can be done by Empedobacter brevis on leachate.
