摘要: Nonylphenol (NP) biodegradation in river sediment using Stenotrophomonas strain Y1 and Sphingobium Y2 were proved to be an effective strategy remediate NP pollution our earlier study. The purpose of this study is investigate the influence glucose addition on their ability degrade both liquid cultures microcosms. shift bacterial community structure relative abundance degraders microcosms characterized terminal restriction fragment length polymorphism analysis. proportion NP-degrading alkB sMO genes was assessed quantitative polymerase chain reaction (PCR) assay. growth its efficiency inhibited by supplementation, while gene increased. However, degradation, as well added gene, enhanced glucose-amended inoculated with Y2. Moreover, external altered structures bioaugmented microcosms, depending level dosage.
