[Hydrolytic activity of marine bacteria associated with the mussel Mytilus trossulus].

The ability to produce hydrolytic enzymes--DNAses, RNAses, alkaline phosphatases, chitinases has been studied in 316 strains of bacteria isolated from mussel Mytilus trossulus. Strains of Vibrio spp. produced all the spectrum of examined enzymes, bacteria of Pseudoalteromonas genus produced alkaline phosphatase and DNAse. Chitin-degrading enzymes were found in Vibrio and Cytophaga--Flavobacterium--Bacteroides group. Bacillus and Vibrio spp. strains produced most actively RNAses. The presence of proteinases, amylases and lipases has been found in all tested groups of bacteria. The antagonistic activity of a number of isolated strains against Candida albicans, Proteus vulgaris and Escherichia coli has been studied.
