从泥炭生物滤池中分离到一株能氧化二甲基硫醚（DMS）的噬酸假单胞菌DMR-11。DMS作为单一碳源或能源不被降解，但在含有机碳源的培养基中被共降解。在30 °C下，热处理的葡萄糖培养基中DMS的去除速率为1.12×10− 17 mole/h细胞。二甲基亚砜（DMSO）是DMS氧化的唯一产物，按化学计量形成。DMS在过量DMSO中可逆地演变。菌株DMR-11的无细胞提取物在NADPH存在下氧化DMS。
Pseudomonas acidovoransDMR-11, capable of oxidizing dimethyl sulfide (DMS), was isolated from peat biofilter. DMS as a sole carbon or energy source was not degraded, but it was co-degraded in the medium containing organic carbon sources. The removal rate of DMS in heat-treated glucose medium was 1.12×10−17mole/h cell at 30 °C. Dimethyl sulfoxide (DMSO) was the only product of DMS oxidation and was formed stoichiometrically. DMS was reversibly evolved in excess of DMSO. The cell free extract of strain DMR-11 oxidized DMS in presence of NADPH.
