摘　　要：为了探究环境因子对微生物降解三氯卡班的影响,以鞘氨醇单胞菌为研究对象,分析了氮源、温度、盐度等因子变化条件下,鞘氨醇单胞菌对三氯卡班的降解性能。结果表明:鞘氨醇单胞菌能高效降解三氯卡班,氮源对鞘氨醇单胞菌在72h内对三氯卡班的降解有促进作用,降解率达96.70%以上;当温度为25℃和35℃时,菌体对TCC的降解率较高,分别为88.67%和91.00%;低盐对菌体降解三氯卡班有促进作用,高盐对菌体降解TCC胁迫作用不明显,可见鞘氨醇单胞菌具有强耐盐性。In order to explore the influence of environmental factors on microbial degradation of triclorocarban,sphingosinomonas was taken as the research object to analyze the degradation performance of triclorocarban by sphingosinomonas under the conditions of changes in nitrogen source,temperature,salinity and other factors.The results showed that:sphingosinomonas can effectively degrade triclocarban,and the nitrogen source can promote the degradation of triclocarban within 72 h,and the degradation rate is more than 96.70%.At 25°C and 35°C,the degradation rates of TCC were 88.67%and 91.00%respectively.Low salt can promote the degradation of triclorocarban by bacteria,but high salt has no obvious effect on the degradation of TCC by bacteria.It can be seen that sphingosinomonas has strong salt tolerance.
