Abstract: We detected, enumerated and isolated atrazinedegrading bacteria from herbicide contaminated soil by improved agar SM. We found that atrazine degraders constituted a major component of microbial communities in industrially contaminated soils, but a minor component in agricultural soils. We also analyzed targeting genes trzN and atzABC with multiplex PCR, which indicated that trzN and atzABC combination included degraders were prevalent in Shandong agricultural and industrial soils. Due to elimination of enrichment bias, direct isolation was more favorable for the diversity analysis of atrazine degrading bacteria.

Key words: direct isolation, atrazinedegrading bacteria, trzN;atzA
