3.5.4.42 degradation biotic interaction between earthworms and the bacterial community involved in degradation of the herbicide atrazine in a maize-cropped soil, earthworms significantly affect the structure of the soil bacterial communities in the biostructures, they reduce the size of the population of Pseudomonas sp. ADP, thereby contributing to the diminution of the atrazine-degrading genetic potential in soil microsites 668648 3.5.4.42 degradation broad level bacterial community interactions that are involved in atrazine degradation in nature 668647 3.5.4.42 degradation broad level bacterial community interactions that are involved in atrazine degradation in nature, Nocardia sp. plays a crucial role for stable maintenance of the degrader community, dechlorination of atrazine is carried out exclusively by Nocardia sp. which apart from the atzC gene contains the trzN gene 668647 3.5.4.42 degradation enzyme degrades the herbicide atrazine, biodegredation in the microcosm appears to occur predominantely by Nocardioides sp. to yield cyanuric acid, which can be mineralised by other relatively ubiquitous microbes -, 670484 3.5.4.42 degradation novel atrazine catabolic pathway combining trzN with atzB and atzC, the gene products dechlorinate and then dealkylate atrazine -, 668653 3.5.4.42 molecular biology hybridization studies localize atzC together with TrzN and atzB to a 380-kb plasmid in Arthrobacter aurescens strain TC1 -, 667248
