共代谢基质促进铜绿假单胞菌降解三十六烷的研究

Influence of Co-metabolism Substrates on Hexatriacontane Biodegradation by Pseudomonas aeruginosa LJ06

为了提高长链烷烃的生物降解效率,对共代谢基质促进长链烷烃降解技术进行了研究。通过铜绿假单胞菌LJ06对三十六烷的降解试验,确定豆油为最佳的共代谢基质,其最佳添加质量浓度为800 mg/L。在含有质量浓度为800 mg/L豆油和200 mg/L三十六烷的共代谢体系中,铜绿假单胞菌LJ06对三十六烷的降解率可达87.2%,是无豆油体系的1.51倍。

In order to promote the biodegradation ability of long chain alkane, the effects of co-metabolism substrates system were studied. Using the strain LJ06, a pseudomonas aeruginosa, to carry out degradation experiments of hexatriacontane, soybean oil was determined as the best co-metabolism substrate and the optimal addition amount was 800 mg/L. When the co-metabolism system contained 800 mg/L soybean oil and 200 mg/L hexatriacontane, the degradation rate of hexatriacontane could reach 87.2%by PseudomonasaeruginosaLJ06. It was 1.51 times contrast to the system without soybean oil.
