水体中秋兰姆特效降解菌的筛选及其降解性能研究

Study on the Screening and Characterization of Special Effective Bacteria of Degrading Thiuram in the Waterbody

从某橡胶厂废弃物堆积场采集受秋兰姆污染的土壤中分离出TM1、TM2、TM33株单菌,分别加到一定浓度秋兰姆的模拟水中,通过实验优化出秋兰姆最佳降解条件,得出单菌株TM1对水样中的秋兰姆降解能力最大。将3株单菌按一定方式混合制成T1、T2、T3、T44组混菌,用单菌降解秋兰姆的最优条件对4组混菌进行降解性能实验,其中混菌T1对秋兰姆降解率最高,降解率可达95.77%。

Three odd bacteria named TM1, TM2 and by thiuram in a landfill of a rubber-manufactured factory TM3 were screened from the soil contaminated and then these bacteria were added into the water with a certain concentration of thiuram. Experimental results show the best conditions with the highest ability to degrade thiuram and TM1 has the highest ability to degrade thiuram among the three bacteria. The four new bacteria （ T1 ,T2,T3 and T4 ） mixed with the three odd bacteria by a certain form have been used to study the ability of degrading thiurarn under the former optimized conditions,and the T1 mixed bacteria has the highest ability with degrading rate of thiuram of 95.77%.
