Production of pectinase by Bacillus subtilis using solid-state substrates

Pectinase or pectinolytic are enzymes, which degrade pectin substances and are of great importance to the food industry. It has been reported that microbial pectinases account for 25% of the global food enzymes sales. These enzymes have been used in several conventional industrial processes, such as textile, plant fiber processing, tea, coffee, oil extraction, treatment of industrial wastewater. An alternative for the production of these enzymes is solid-state fermentation (SSF). The purpose of this research was to optimize the production of pectinase by solid substrate fermentation using lignocellulosic wastes ( wheat straw, rice straw ) and pectic substance such as citrus pulp ( lemon, orange ).
