| Abstract: | 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. |
