Approximately 800 yeasts and other fungi, representing over 70 species, were tested for extracellular caseinolysis. Isolates of a variety of genera, including Aureobasidium, Cephalosporium, Endomycopsis, Kluyveromyces, and numerous sporobolomycetes, demonstrated significant proteolytic activity. Caseinolysis was not necessarily correlated with gelatin liquefaction or with albuminolysis. Numerous fungi showed significant proteolysis at 5 C. The most active organisms were isolates of Candida lipolytica, Aureobasidium pullulans, Candida punicea, and species of Cephalosporium. Taxonomic and ecological implications of proteolytic activity are discussed.
