Abstract

Leachate treatment containing methylmercury (CH3Hg+) can be done by using biodegradation method. Bacteria used in methylmercury biodegradation of the bacteria Empedobacter brevis. This study aims to examine the ability of  bacteria in degrading methylmercury 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 methylmercury content in the biodegradation process. The results showed that biodegradation of methylmercury 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.
