Superior performance and mechanism of chlorobenzene degradation by a novel bacterium.

ABSTRACT: A newly isolated strain was identified as Ochrobactrum sp. by 16S rRNA sequence analysis and named as ZJUTCB-1. The strain was able to degrade mono-chlorobenzene (CB) as the sole carbon and energy source under aerobic conditions. This study is the first to report the degradation of CB by the genus Ochrobactrum. The degradation rate of CB reached 170.9 μmol L^-1 h^-1, which is at least 6 times higher than the previously reported data. The strain can efficiently degrade CB under a rang of temperatures (30-40 °C) and pH (6.0-7.0) with optimum at 40 °C and pH 7.0. Salt concentration higher than 0.05 mol L^-1 remarkably reduced the biodegradation capability. Moreover, true oxic condition was not an essential element for biodegradation given that the C
