【Abstract】 A strain of Acinetobacter sp.51-2 wascapable of degrading acetonitrile and utiliz-ing various nitrile compounds,such as pro-pionitrile,butyronitrile,acrylonitrile and soon.The ability and speed of degrading ace-tonitrile were quite strong and fast.Strain51-2 could degrade 25 g/L acetonitrile in 48 hby adapted cells.The efficiency of degradingacetonitrile was closely related to the condi-tions of culturing bacterial cells.The reac-tion temperature and present metals appearedto have a little effect on degradation of ace-tonitrile.更多还原
