代谢
一种分解苯氧基醋酸类除草剂的酶制剂是由土壤中的节杆菌属物种制成的。粗提物可以降解2,4-D, 4-氯-2-甲基苯氧基醋酸,以及2-和4-氯苯氧基醋酸。由2,4-D, 4-氯-2-甲基苯氧基醋酸,以及2-和4-二氯苯氧基醋酸形成的产品被鉴定为2,4-二氯苯酚, 2-甲基-4-氯苯酚,以及2-和4-氯苯酚。该细菌提取物能够代谢儿茶酚以及3-甲基、4-氯和3,5-二氯儿茶酚。
An enzyme preparation metabolizing phenoxyacetate herbicides was made from a soil arthrobacter species. Crude extracts degraded 2,4-D, 4-chloro-2-methylphenoxyacetic acid, and 2- and 4-chlorophenoxyacetates. The products formed from 2,4-D, 4-chloro-2-methylphenoxyacetic acid, and 2-, and 4-dichlorophenoxyacetates were identified as 2,4-dichlorophenol, 2-methyl-4-chlorophenol, and 2- and 4-chlorophenols. The bacterial extract was capable of metabolizing catechol and 3-methyl, 4-chloro-, and 3,5-dichlorocatechols.
