Abstract

It is established that bacteria with the ability to produce enzymes hydrolyzing carbohydrates of different complexity degrees are associated with the intestine digestive-transport surfaces of the eelpout Lota lota (L.) and of cestoids Eubothrium rugosum parasitizing in it. The release by bacteria of enzymes hydrolyzing not only complex carbohydrates, but also disaccharides, decreases the energy expenditures of the host and parasite for synthesis of their own hydrolases and increases the glucose concentration near the transport surfaces, which allows all members of this formed community to use glucose. The total amylolytic activity (TAA) of enzymes and the α-amylase activity of the studied bacteria are realized in a wide range of pH values. The levels of the enzyme general amylolytic activity and of bacterial α-amylase activity under the experiment conditions are comparable with similar characteristics of enzymes desorbed from the studied surfaces and participating in the membrane digestion processes in the host and parasite, which can suggest a significant contribution of the symbiotic microflora enzymes to digestion of the host and parasite.
