Popis:	Production of extracellular proteolytic enzymes was studied in thermophilic fungi Paecelomyces variotii and Aspergillus carneus, isolated from thermal springs of the Barguzin Valley. Protease synthesis in these fungi requires protein in the ambient medium. The composition of the enzymes secreted by A. carneus depends on the kind of carbohydrate present in the medium. The proteinase of this fungus digests synthetic substrates and gelatin (optimum pH 7.7). It belongs to neutral serine proteases. Extracellular P. variotii proteases digest gelatin (optimum pH 9.7–10.4). According to inhibitor analysis data, they can be classified as alkaline metalloproteinases and serine proteinases.
