DEGREDATION OF PERCHLORATE WITH PHENOL AS A SOLE CARBON SOURCE BY AN ISOLATED STRAIN PSEUDOXANTHOMONAS SP.Abstract
Phenol was used as a sole carbon source for the perchlorate biodegradation as reported for the first time. Isolated bacterial species Pseudoxanthomonas sp. isolated from a sewage sludge consortium was found to reduce perchlorate while taking phenol as electron acceptor. The growth and perchlorate degradation were analyzed in a batch system along with the degradation profile of phenol by the microbial culture. The effect of the co-pollutants (nitrate, chlorate, nitrate, phosphate) was also considered as part of the present study, where nitrate was found to be the most significant. Perchlorate was significantly removed by the culture involving subsequent phenol degradation in a continuous packed bed system anaerobically from synthetic wastewater.
