Biological degradation of a leachate with microorganisms was studied. Microbial cells could grow up in leachate without adding other substates and extra cellular enzymes were produced. The concentration of ammonia and COD decreased. At the same time we suggest, other substances in leachate would be also degraded by microorganisms. As a starter the culture of white-rot fungi was inoculated in leachate. During 7 days 30% of COD, 82% of BOD and 67% of total ammonia were removed. The reaction velocity of COD and ammonia were 0.01 ～ 0.085/day and 0.082 ～ 0.179/day, respectively. The removal rate of COD was lowere than that of ammonia, but it means that this microbial degradation can be very useful to treat a leachate with higher ammonia content. In the reactor 18% of ammonia was stripped. The nitrate concentrate was under 1 mg/l and there is a suggestion that the most of ammonia was consumed by microbial cells, because of the low nitrification rate. The comparision of the removal rate between with enzyme addition and without showed that the microbial cultivation and enzyme production will stimulate to the removal of many substances.
