摘要
A strain PA-18 was isolated from the active sludge of p-phthalic acid (PTA) wastewater treatment in Yangtze Petrochemical Company. The 16SrDNA fragment was amplified from strain PA-18 by PCR, and the 16SrDNA sequence analysis indicated that strain PA-18 shared 99% 16SrDNA sequence homology with Pseudomonas sp. In the phylogenetic framework of bacterial classification, PA-18 belongs to Pseudomonas sp. Under the condition of temperature 37°C, pH 7.0 and OD660nm 2.0, the PTA decomposition rate of this bacterial strain was beyond 95% after 24 h. Meanwhile, this strain also could treat PTA wastewater with CODCr removal of 85%. p-Phthalic acid was degraded by the strain PA-18 through the intermediate formation of protocatechuic acid in the aerobic state.
