All A. pullulans and W. anomalus strains were able to hydrolyze laminarin (b-1, 3-glucanase activity). Moreover, all A. pullulans strains showed pectinolytic and proteolytic (skim milk and gelatin) activities. On the opposite, no extracellular enzyme activity was detected for M. pulcherrima and S. cerevisiae strains. No strain showed chitinase activity.
