[The lysozyme-antilysozyme functional system in hydrobionts and its role in forming aqueous biocenoses].

Lysozyme activity has been evaluated in hydrobionts of different trophic levels: algae, zooplankton and germs. The existence of the functional system "Lysozyme of hydrobionts--antilysozyme of germs", functioning as a regulating element in the formation of aqueous microbiocenosis, has been substantiated on the basis of data provided by laboratory experiments and investigations carried out in natural water pools.
