Abstract

Production and viscometric assay of endoglucanse by Aspergillus niger

Author(s): G.Narasimha, A.Sridevi

In this study, a fungal strain Aspergillus niger was isolated from soil contaminated with effluents of cotton ginning mill for cellulase production. The cellulolytic property of fungal culture was confirmed by Plate screening method. Formation of clear yellow zone of inhibition on Congo-red agar medium is an indication of endoglucanase activity of fungal strain. The endoglucanse activity was measured by viscometric method. The maximumreduction in CarboxyMethyl Cellulose viscositywith 98.77 percentages at 70 minutes is an indication of improved endoglucase activity of Aspergillus niger.
