title: [Lysozyme of hydrobionts and its role in self-purification of water reservoirs].
abstract: Model experiments were carried out to study the effects of hydrobiont lysozyme on self-purifying processes of water reservoirs through its participation in the formation of a community of destructive microorganisms. Lysozyme-resistant forms have been found to lie at basis of bacterial cenosis of the Urals, among which there are lysozyme-active and anti-lysozyme-active ones, their population shows an inverse relationship. The exogenous lysozyme that enters the water reservoir in the period when there is a change in the dominant forms of hydrobionts affects the composition of bacterial cenosis by preserving anti-lysozyme-activity with a high activity (6-8 (g/ml), which causes a change in the microbial community of water reservoir, thus affecting the processes of its self-purification. The bacteria having ALA, which do maintain the capacity of a water reservoir for self-clearance from organic substance, persist under the action of endogenous lysozyme of phyto- and zooplankton among saprophytic microorganisms that are destructive agents in the biocenosis.
