| Biphenyl is natural and synthetic aromatic compounds. This pollution has caused pubic concern due to its wide-spread use, improper handling, as well as its low degradability, strong bioaccumulation and high toxicity in the environment. Two bacterium strains, G-1 and G-2, were isolated from an activated sludge of a chemical factory wastewater treatment plant in China. Both the strains can use biphenyl as sole carbon and energy sources. The G-1 almost complete degraded it within 7 days, but can not utilized 3,3',4,4'-tetrachlorobiphenyl (PCB77) as sole carbon source. Although, train G-2 degrade biphenyl slower than G-1, it can utilize PCB 77. Strain G-2 was identified as Paracoccus according to phylogenetic similarity of 16S rRNA gene sequence. |
