Abstract

Endomycopsis capsularis 311/1 is a good producer of extracellular α-glucosidases. An enzyme exhibiting maltase and transglucosidase activities is released at the beginning of the logarithmic phase of growth. The enzyme is able to produce isomaltose and panose. Starch-hydrolysing enzymes are excreted into the medium at the end of the logarithmic phase of growth: an enzyme of α-amylase type is produced in the presence of calcium carbonate and pH about 6.0, whereas an enzyme of the amyloglucosidase type is formed in the absence of calcium carbonate and pH about 4.0. The enzyme production is identical in media containing different carbon sources, glucose, maltose or soluble starch.
