摘要：

Monochloromethane (MeCl) was biotransformed by a mixed culture of anaerobic bacteria which had been enriched to utilize dichloromethane as the sole source of carbon and energy. Cells grown in dichloromethane-salts medium catalyzed the transformation, whereas sucrose-grown cells were inactive. MeCl disappeared almost totally, and the methyl group was recovered in a yield of 80-90% as methanethiol and traces of dimethyl sulfide, whose identities were confirmed by GC-MS. The methyl transfer was heat-labile, and free aquocobalamin did not promote the reaction, which was apparently enzymically catalyzed.
