Аннотация
The in vitro effect of Roundup herbicide at a concentration of 25 μg/L on the activity and temperature characteristics (temperature dependence, activation energy Eact, and Q10 temperature coefficient) of maltase in the intestinal mucosa of the juvenile sander, perch, roach, and common carp has been studied. The magnitude and direction of the effect depends on the fish species and the incubation temperature. Roundup does not affect the temperature optimum for maltase (60°C for perch and sander; 50°C for roach and carp). The lower relative activity of the enzyme in the temperature range of 0–30°C indicates a decrease in the efficiency of maltose hydrolysis, while lower Eact values indicate adaptive changes in this parameter in the presence of Roundup.
