摘要: Biphenyl (BP)-degrading bacteria were identified to degrade various polychlorinated BP (PCB) congers in long-term PCB-contaminated sites. Exploring BP-degrading capability of potentially useful was performed for enhancing PCB bioremediation. In the present study, bacterial composition sediment sample first investigated. Then extracellular organic matter (EOM) from Micrococcus luteus used enhance biodegradation. The effect EOM on community investigated by combining with culture-dependent and culture-independent methods. obtained results indicate that Proteobacteria Actinobacteria predominant sediment. M. luteus could stimulate activity some difficult-to-culture degraders, which contribute significant enhancement response addition mainly Rhodococcus Pseudomonas belonging Gammaproteobacteria respectively. This study provides new insights into exploration functional points out broader BP/PCB degrading, be employed PCB-bioremediation processes.
