Isolation and identification of Profenofos degrading bacteria.

ABSTRACT: An enrichment culture technique was used to isolate bacterial strains responsible for the biodegradation of profenofos in a soil from Hubei province of central China. Two pure bacterial cultures, named W and Y, were isolated and subsequently characterized by sequencing of 16S rRNA genes and biochemical tests. Isolate W showed 96% similarity to the 16S rRNA gene of a Pseudomonas putida unlike Y which showed 99% similarity to the 16S rRNA gene of Burkholderia gladioli. Both strains grew well at pH 5.5-7.2 with a broad temperature profile ranging from 28° to 36 °C. Bioremediation of profenofos-contaminated soil was examined using soil treated with 200 ug g(-1); profenofos resulted in a higher degradation rate than control soils without inoculation. In a mineral salt medium (FTW) reduction in
