Biodegradation of di?n?butyl phthalate by mangrove microorganism Rhodococcus ruber 1K
红树林细菌Rhodococcus ruber 1K降解邻苯二甲酸二丁酯的研究

A di-n-butyl phthalate (DBP)degrading bacterium Rhodococcus ruber was isolated from mangrove soil,and its degrading characteristics were studied.The results showed that the bacterium could grow well on the substrate with DBP as the sole source of carbon and energy,and the DBP of 50 mgL~(-1) could be completely degraded after 48 h.Under aerobic condition,the tentative pathway proposed for DBP degradation was through monoester initially,then phthalic acid,and finally CO_2 and H_2O.
