Abstract
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 14 d 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.
