The metabolism of atrazine herbicide by Nocardia, a soil bacterium previously shown to degrade the herbicide to 4-amino-2-chloro-1,3,5-triazine, has been studied. The primary route of the metabolism appeared to be N-dealkylation and was similar to that found in several fungi. The data suggested that the isolated dealkylated metabolites were precursors of 4-amino-2-chloro-1,3,5-triazine. The supposed metabolites 4-alkylamino-2-chloro-1,3,5-triazines were synthesized but there was not direct proof of their involvement in the degradation process.
研究了一种土壤细菌 Nocardia 对莠去津除草剂的新陈代谢,这种细菌以前曾被证明能将除草剂降解为 4-氨基-2-氯-1,3,5-三嗪。新陈代谢的主要途径似乎是 N-脱烷基化,与在几种真菌中发现的途径相似。数据表明,分离出的脱烷基代谢物是 4-氨基-2-氯-1,3,5-三嗪的前体。虽然合成了假定的代谢物 4-烷基氨基-2-氯-1,3,5-三嗪,但并不能直接证明它们参与了降解过程。
