Fig. 3From: Occurrence, diversity and community structure of culturable atrazine degraders in industrial and agricultural soils exposed to the herbicide in Shandong Province, P.R. ChinaThe limits of Pseudomonas sp. D3-1l and A. ureafaciens DnL1-1 detection in soil by PCRs targeting atrazine degradation genes. Lanes are designated by titers of Pseudomonas sp.D3-1l (left panel) and A. ureafaciens DnL1-1 (right panel) CFU added per 1Â g of S1 soil. Lane N and C are, respectively, no template control and a control in which DNA isolated from non-inoculated S1 soil was used as a template. The primer pairs for trzN, atzA, atzB and atzC were trzN1114f/trzN1271r, atzA655f/atzA982r, atzB181f/atzB316r and atzC340f/atzC552r, respectively. Lanes M contain a 100Â bp DNA Ladder (Takara Biotechnology (Dalian) Co., Ltd., China)Back to article page
