可降解蒽细菌的分离与生长特性研究
Research on the Isolation and Growth Characteristics of Anthracene-degraded Bacteria
摘要
Abstract
[ Objective] The research aimed to supply theoretical foundation for bio-recovery of polycyclic aromatic hydrocarbon (PAHs) pollution, such as anthracene pollution. [ Method] The anthracene-degraded strain E12 was screened out from active sludge of sewage processing factory through enrichment culture. The growth curve of this strain and its degrading curve on anthracene were determined and the influence of factors including different anthracene concn. and initial pH values on the its degraded efficiency was researched. [ Result] The primary identification indicated that the strain E12 belong to Aeromonas and could grow in the medium with anthracene as sole carbon source. When the initial concn. of anthracene was lower than 900 mg/L, the strain concn. was increased along with the increase of anthracene concn. When the anthracene concn. exceeded 900 mg/L, the strain concn. was decreased significantly. The strain could grow in both weak acid and weak base environments and the optimum pH value for its growth was 6.5. The innoculation amount of bacterial suspension also showed obvious influence on its growth and the optimum innoculation amount was 2.0％. [ Conclusion] The optimum condition for E12 strain degrading anthracene was as follows: the anthracene concn. was 900 mg/L and the pH value was 6.5. The degraded rate of anthracene could reach 70.5％ after culture for 148 h under this condition.关键词
