Biodegradation of di-n-butyl phthalate by mangrove microorganism Rhodococcus ruber 1K

Abstract

Abstract: 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 mg稬^-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 CO₂ and H₂O.

Key words: Di-n-butyl phthalate, Biodegradation, Mangrove
