Plate numbers of bacteria and relative incidence of strains capable of mineralization of 2,4-dichlorophenoxyacetic acid (2,4-D) in chernozem samples incubated for 14d with the herbicide (50 ppm) in the presence or absence of glucose (1000 ppm) were compared. Whereas the total number of bacteria increased 1.2-fold in the variant with 2,4-D and 2.4-fold in the variant with glucose and the herbicide, the number of 2,4-D-mineralizing bacteria increased 12.1-fold and 34.2-fold, respectively. In a collection of 96 isolates of soil bacteria substantially more strains capable of degradation of 2,4-D in the presence of glucose were detected as compared with the variant without it, indicating that processes of cometabolic type are involved during the degradation of this herbicide in the soil.
比较了黑钙土样品中细菌的平板计数以及在有或无葡萄糖（1000 ppm）存在的情况下，与除草剂（50 ppm）一起培养14天的能够矿化2,4 - 二氯苯氧乙酸（2,4 - D）的菌株的相对发生率。在含有2,4 - D的变体中细菌总数增加了1.2倍，在含有葡萄糖和除草剂的变体中增加了2.4倍，而能够矿化2,4 - D的细菌数量分别增加了12.1倍和34.2倍。在96株土壤细菌分离物中，与没有葡萄糖的变体相比，检测到在有葡萄糖存在的情况下能够降解2,4 - D的菌株明显更多，这表明在土壤中该除草剂降解过程涉及共代谢类型的过程。
