An assay has been developed to detect production of extracellular β ‐galactosidases by fungi during growth on a defined medium containing polygalacturonate. Using this method strains of the yeast‐like fungus Aureobasidium pullulans and the filamentous fungus Penicillium brevicompactum which secrete β ‐galactosidase have been isolated. Seventy strains of yeast were tested but none secrete detectable extracellular β ‐galactosidase during growth on polygalacturonate agar medium.
