Abstract

The aim of this study was to isolate and identify marine yeast strains from seawater, sediments seaweed, and fish/shrimp coproducts. Over six-different identified species of marine yeast, Yarrowia lipolytica strain having a proteolytic activity. Enzyme extracts showed that the relative optimal enzymatic activity was reached at pH = 9.0 and temperature of 45.0° C.
