Popis: | herbicides, have a broad spectrum effect on weeds, in relatively low doses and with a much reduced toxicity on livestock. In this study were used two herbicides: dacsulfuron with the active substance chlorsulfuron (0.005 - 0.035 μg/g soil) and butoxone with the active substance MCPB-Na (0.005 - 0.035 mg/L/g soil). The samples were collected from a depth of 0-20 cm from chernozem soil. The effect of herbicide was estimated by measuring the activity of catalase, actual and potential dehydrogenase, urease and cellulase activities. All samples being incubated for 10 days at 27°C using Sapp medium for isolation and study of cellulosolytic bacteria. The inhibitory effect of the tested herbicides was the most intense for the urease and dehydrogenase enzymatic activities. The most resistant cellulosolytic bacteria to the effects of dacsulfuron were Cellfalcicula fusca, Cellfalcicula viridis, Cellvibrio fulvus and Fuseaux veris and for butoxone Cellfalcicula mucosa, C. viridis and C. fulvus. |
