Effect of Cultivation and Storage pH on the Production of Multiple Forms of Polygalacturonase by Aspergillus-Niger
The production of multiple forms of extracellular polygalacturonase by Aspergillus niger is directly dependent on the pH of maintenance media. The pH of cultivation medium as well as the carbon-source are only secondary factors with limited influence on this production.
