ASSESSMENT OF THE FUNCTIONAL-STATE OF THE BLACK-SEA WATER BY THE LEVEL OF ENZYMATIC HYDROLYTIC ACTIVITIES

Amylolytic (AA) and proteolitic (PA) enzymatic activities have been st udied on the research ship <<Vityaz>> (September-October, 1992) in the sea water at various horizonts of the 0-100 m layer in Golubaya Bay s lope and in open water of the Zmeinyi island and Fillofornoe field she lf zones. Irregular small-scale vertical variability of AA and PA was observed. The activities in the shelf water were much higher than thos e more distant from the shore or in the abyssal zone of the Golubaya B ay slope. Express enzyme-substrate tests allowed to reveal regions unf avorable to the enzymatic process. Promising development of enzymatic methods for assessment of the functional state of natural water is dis cussed.
