In order to bioremediating of phorate contaminated soil by microbial consortia, three degrading bacteria in different combinations were inoculated into the phorate contaminated soil. The residual phorate and its metabolites were determined. The results showed that in 42 days the degradation rates of phorate by any two bacteria ( Brevibacterium frigoritolerans + Bacillus aerophilus , Bacillus aerophilus + Pseudomonas fulva and Brevibacterium frigoritolerans + Pseudomonas fulva ) were 94.09%, 97.15% and 97.42%, respectively. However the degradation rate of phorate by three bacteria was 98.31%. The microbial consortia consisted of three degrading bacteria had the lowest content of phorate sulfone and phorate sulfoxide in soil. Therefore, the microbial consortia consisted of three degrading bacteria could significantly reduce the residual phorate and its metabolites in soil.
