Influence of culture conditions on mycelial structure and polygalacturonase synthesis of Aspergillus niger.

Biosynthesis of polygalacturonase (PG) by A. niger strain R 1/214 correlates with the morphology of mycelium in submerged culture. The mean specific PG-synthesis (PG-U.g-1.h-1) increases with the degree of compactness of mycelium. PG-production can be optimized by a precise adjustment of the culture conditions after direct spore inoculation (diffuse… CONTINUE READING
