| Abstract: | Activity of proteinases of the content of intestines (chyme) of the benthos-eater crucian carp Carassius carassius fed different diets during prolonged exposure to water is studied. In the process of exposure of the chyme to water, the
activity of proteinases decreases. Activity of glycosidases may increase, maximally during the first three days of exposure.
This phenomenon suggests the important role of enzymes of the enteral microflora in processes of destruction of protein and
carbohydrate components of the suspension and especially of organic detritus. |
