✦ Synopsis
The total formation of p-glucosidase by the wild strain of Aspergillus niger ZIMET 43 746 is nongrowth-associated. In discontinuous culture the total B-glucosidase activity related to the mycelium is increasing with the age of the mycelium. The complete release of the remaining mycelial-associated B-glucosidase is dependent on the structure of the mycelium. In the cases of the mycelium forms pellets throughout the growth phase than the release of 8-glucosidase is accelerated compared to the release from loosly branched mycelium. Increasing shear stress caused by increasing of the impeller speed promotes the formation of pellets.
