多环芳烃降解菌的筛选与降解能力测定
Screening of PAHs-degrading bacterial strains and determination of their capability in degrading PAHs
摘要
Abstract
Eight PAHs-degrading bacterial strains were screened out from the enriched culture with PAHs-contaminated soils in Benxi City of Liaoning Province, Northeast China, and the capability of the strains in degrading phenanthrene, phyrene, and benzo[ a ] pyrene with an initial concentration of 50, 50, and 5 mg · L-1 in medium was determined after 28-day incubation at 28 ℃. Among the strains screened out, B3 showed the best degrading effect, with the degradation rate of phenanthrene, phyrene, and benzo [ a ] pyrene being 88.4％, 54. 0％, and 68.4％,while the degradation rate of these compounds by the mixed 8 strains was 87.7％, 35.3％, and 42.0％, respectively. The strain B3 was identified as Pseudomonas sp. , based on its physiological and biochemical characteristics and the sequence analysis of 16S rRNA.关键词
