Abstract
The proteolytic activity of 7 yeast strains belonging to species Candida famata, C. sphaerica, C. intermedia, C. kefyr, Geotrichum penicillatum, Yarrowia lipolytica i Saccharomyces kluyveri were determined. It was shown big variations in the level of activity especially of extracellular proteases of yeasts. The most active were extra- and intracellular proteases of strain Y. lipolytica PII6a. Caseinolytic proteases of all strains were inhibited by PMSF and DFP. Majority of them exhibited optimum at pH 6.5–7.5. Extracellular proteases of yeasts active against hemoglobin had optimum at pH 3.5–4.0.
