摘要
Abstract
Ten strains which can degrade the waste lubricants were isolated from sewage samples of the outfall of a castor oil extraction plant in Inner Mongolia,China,and T-9 strain showed the strongest lubricant degradation ability.The optimal degradation condition of T-9 strain was pH 5.0,and temperature 30 ℃.T-9 strain could grow well in the medium containing 1%~5% NaCl.T-9 strain was identified as Pseudomonas by the colony morphology,physiological and biochemical characteristics.By improved CEC-L-33-A-93 method,the degradation rate of castor oil-based waste lubricants was 72% when incubated for 7 days under the conditions as following: 10 g/L oil,initial pH 5.0,rotation speed of 180 r/min,and 30 ℃.By GC/MS analysis of degradation products,degradation rate was 80%,indicating that the T-9 strain had good castor-based oil degradation ability.关键词
