Abstract

A nucleic acid-based approach was used to investigate the dynamics of microbial community dominated by Xanthobacter autotrophicus GJ10 in the degradation of synthetic wastewater containing 1,2-dichloroethane (DCE). The study was performed over a 140-day period in a nonsterile continuous stirred tank bioreactor (CSTB) subjected to different operational regimens such as nutrient limiting conditions, baseline operation and the introduction of glucose as a cosubstrate.

Abstract

The degradation by a coculture of Pseudomonas putida HS12 and Rhodococcus sp. strain HS51 of 3- and 4-chloronitrobenzenes (CNBs) has been studied. CNBs are used as intermediates in the manufacture of various chlorinated aromatic compounds. The Pseudomonas strain was isolated by analogue enrichment culture using nitrobenzene (NB) as the substrate. The strain possesses a partial reductive pathway for the degradation of NB. Results indicate that the coculture can mineralize 3- and 4-CNBs in the presence of a carbon source.
