Microbial Degradation of Ethylene Glycol Dibenzoate by Rhodococcus sp. 2Cb

摘要

Strain 2Cb that hydrolyzed the ester bond of ethylene glycol dibenzoate (EGDB) efficiently was isolated. We describe its isolation and its identification as a Rhodococcus sp. based on morphological and rDNA sequencing. In a medium containing 0.5% of EGDB at pH 7.0, 30℃, the strain completely degraded EGDB in 30 days. The strain also grew on benzoic acid, p-hydroxybenzoic acid, and protocatechuic acid as the sole source of carbon. Distribution study of EGDB degrading enzymes indicated that the degradation activity was found on the cell surface.
