摘要： The influence of cyfluthrin-degrader, a novel Lysinibacillus sphaericus strain, FLQ-11-1, with respect to biodegradation effectiveness and its effects on soil microbial community simulating in situ, was evaluated. Two 4-kg soil samples containing 100 mg/L of cyfluthrin were set up, one without cyfluthrin degrader inoculation and one inoculated with degrader. The results showed that the cyfluthrin concentration in the inoculated soil declined by 99.45% within 28 days, whereas in strain-free samples, this concentration decreased by 29.1%. The amount of culturable bacteria in the inoculated soil grew faster in the 7 days after inoculation than in the strain-free sample, although it was low in both samples. PLFA profiles of soil after inoculating strain FLQ-11-1 displayed significant difference, with the character of biomark 18:0 negative related to cyfluthrin residue content. microrganisms L. sphaericus and P. amygdali, were only detected in the the soil inoculated with FLQ-11-1, while R. leguminosarum and Nitrosospira sp., were special microbes in the free soil, and twelve bacterium were in common. And strain FLQ-11-1 were the advantage organism in the 28 day, accomplying with the microbial diversity recovery. These results showed that strain FLQ-11-1 could well colonized in the cyfluthrin-polluted soil, although change the indigenous microorganism community diversity in its earlier bioremediation action, but contribute to recover the indigenous microorganisms community with decreasing of cyfluthrin in the soil.
