ENZYMATIC DESTRUCTION OF BIOPOLYMERS IN THE BLACK-SEA WATER UNDER THEINFLUENCE OF NEW-SETTLED PREDATOR MNEMIOPSIS-LEIDYI

Proteolytic and amylolytic activities of sea water were studied in rel ation to population and biomass of jellylike animals during 1994-1996. In the 0-150 m water column, total proteolytic and amylolytic activit ies describing the potential rate of biopolymers hydrolysis varied fro m 10 to 478 U/l. Efficient rates of azocasein and starch hydrolysis (v (1), mg/l per hotel) for sea water were calculated. We carried out cor relation analysis of the biomass and population of Mnemiopsis and othe r jellylike organisms. Potential rates of biopolymer enzymatic hydroly sis in sea water proved to depend on the content ratio of Mnemiopsis-o ther jellylike organisms.
