GC和GC/MS分析脱硫细菌代谢二苯并噻吩的产物

GC/MS AND GC ANALYSIS OF METABOLITES OF DBT BY DESULFURATION BACTERIA

从茂名炼油厂周围土壤中分离得到一株可脱除二苯并噻吩 (DBT)的细菌YC LI 1,用GC/MS方法定性鉴定了该细菌脱除DBT的代谢的有机产物为 2 羟基联苯 (1 OHBP) ,此外试验还证明了DBT中的硫原子代谢为水溶性的硫酸盐。用GC方法测定了该菌种将DBT代谢为 2 羟基联苯的转化率 ,分析结果表明该菌种可有效代谢DBT ,转化率达 90

A dibenzothiophene (DBT) degrading bacterium, YC LI 1, was isolated from soil around Moming refinery. The organic metabolite 2 hydroxybiphenyl of DBT is identified qualitatively by GC MS. Barium chloride (BaCl 2) test proves that the sulfur in DBT is converted to water soluble sulfate. The rate of conversion of DBT was determined by GC method. The analytical results indicate that the YC LI 1 bacterium is very effective for desulfuration.
