[Some problems related to the regulation of the glucoamylase synthesis by Endomycopsis fibuligera 21].

The effect of different sources of carbon and other components on the glucoamylase synthesis by Endomycopsis fibuligera 21 was investigated. It was demonstrated that the enzyme was actively synthesized after the complete utilization of the carbon sources and the synthesis was not related to the presence of specific substrates in the medium. It was shown that water immersed washed cells of the producer accumulated high glucoamylase activity. It is suggested that the above yeast synthesize glucoamylase in the constitutive way and that the process may be regulated by catabolite repression.
