Yeast belonging to various genera were screened for extracellular protease activity. Of the 119 strains examined the most prolific protease producers belonged to the genera Candida, Kluyveromyces and Hansenula . No strains of Sacharomyces were found to secrete protease. In general only those proteases secreted by the genus Candida possessed chill‐proofing activity. However one strain of Debaryomyces and one of Pichia also produced proteases with chill‐proofing activity.
