Abstract

In vitro studies of the effect of the herbicide Roundup (25 µg/L) on the activity of glycosidases that hydrolyze starch in the intestinal mucosa and chyme of typical (pike Esox lucius L., zander Sander lucioperca (L.), and wels catfish Silurus glanis L.) and facultative (common perch Perca fluviatilis L. and burbot Lota lota (L.)) ichthyophages have revealed the dependence of the strength and direction of its effect on the fish species, as well as on the localization of enzymes, temperature, and pH. The greatest inhibitory effect of Roundup on the glycosidase activity of intestinal mucosa and chyme was demonstrated at acidic pH levels. The decrease in temperature at neutral pH level, as a rule, eliminates the inhibitory effect of Roundup on the glycosidases of intestinal mucosa, although the inhibitory effect increases at acidic pH levels.

综述对温度和pH的影响，典型和兼性噬菌体肠中糖苷酶活性的影响

摘要

体外研究除草剂农达（25 µg / L）对水解典型（派克Esox lucius L.，zander Sander lucioperca（L.）和威尔士cat鱼）肠粘膜和食糜中糖苷酶活性的糖苷酶活性的体外研究。Silurus glanis L.）和兼性（鲈鱼Perca fluviatilis L.和Burbot Lota lota）（L.））鱼噬菌体揭示了强度和作用方向对鱼类的依赖性，以及对酶的定位，温度和pH值的依赖性。在酸性pH值下，农达对肠粘膜和食糜的糖苷酶活性具有最大的抑制作用。通常，在中性pH值下温度的降低消除了Roundup对肠粘膜糖苷酶的抑制作用，尽管在酸性pH值下抑制作用增强。
