一株丁草胺降解菌 BTC-3的分离鉴定及降解特性研究
Isolation, Identification and Degradation Characteristics of A Butachlor-degrading Bacterial Strain BTC-3
摘要
Abstract
A butachlor-degrading bacterial strain named BTC-3 was isolated from a soil sample near the outfall of a pesticide factory, which had produced butachlor for many years.BTC-3 could degrade more than 85%of 100 mg/L butachlor in inorganic salt culture medium with butachlor as sole carbon source within 6 days.Combining the culture, physiological and biochemical character-istics with 16S rRNA sequence analysis, strain BTC-3 was identified as Bacillus sp.The optimal temperature and pH-value for the degradation of butachlor by BTC-3 were 30℃and 7, respectively.When the inoculation amount was less than or equal to 3%, the degrading rate increased with the increase in the inoculation amount.When the initial concentration of butachlor was less than or e-qual to 100 mg/L, the higher the concentration of butachlor, the better the effect of degradation.关键词
