New formulation of production media for submerged cultivation of aspergillus niger for production of pectinase

Pectinase is a generic term that used from derivation of the pectin. Pectin is a complex class of carbohydrates polymer which composed of members galacturonic acid that linked through the a-1-4 glycosidic linkage and it is widely found in the primary cell walls or at the middle lamella of higher plants . Furthermore, Among different biofactories of pectinases, the filamentous fungi provide a potentially high yielding and relatively cheap option and the genus of Aspergillus has been used with a success as a production host . Therefore, the objective of this research is to develop industrial production media and a cultivation strategy for the production and secretion of pectinases in a semi-industrial scale by A. niger. In this study, the submerged cultivation was chose as a cultivation strategy for the production and secretion of pectinase in a semi-industrial scale by A. niger
