Rhodococcus sp. JDC-11, capable of utilizing di-n-butyl phthalate (DBP) as the sole source of carbon and energy, was isolated from sewage sludge and confirmed mainly based on 16S rRNA gene sequence analysis. The optimum pH, temperature, and agitation rate for DBP degradation by Rhodococcus sp. JDC-11 was 8.0, 30 degrees C, and 175 rpm, respectively. In(More)
Four di-butyl-phthalate(DBP)-degrading bacterial strains, JDC-1, JDC-8, JDC-9 and JDC-12, were isolated from soil. The strains were gram positive. The 16S rRNA sequence analysis revealed that the four strains had similarities of 99% with Arthrobacter sp.. According to the morphologic, physiobiochemical characteristics and the analysis of their 16S rRNA, all(More)
A gram negative isolate designated JDC-41 was obtained from river sludge using mixtures of phthalate esters as the sole source and energy. The isolate was identified as Ochrobactrum sp. based on its 16S rRNA gene sequence. Over 87% of supplied di-n-butyl phthalate (DBP) was degraded by JDC-41 in a pH neutral mineral salts medium at 30 degrees C within 48 h.(More)
