By keeping in mind the extensive industrial and biotechnological applications of pectin lyase the present study reports on the influence of culture conditions on pectin lyase production potential of fungal strain Aspergillus oryzae under SSF. In the present study, a novel approach was applied that dealt entirely with the use of different residual wastes from various field crops (waste materials from wheat straw, apple pomace, lemon peel, orange peel and municipal paper) to obtain the product of industrial interest. The present study was also focused on providing a potential solution for the management of a large magnitude of solid wastes.
