%X The enzyme glucose oxidase was produced by fermentation technology, using Aspergillus niger as fermentation organism and rice polishing as substrate. Maximum production of enzyme (3.42 U mL 1) was recovered at substrate level of 2% after 36 h of submerged fermentation. The pH for the optimal production of enzyme was found to be 4. Addition of salts such as urea (0.3%), CaCO3 (0.04%) and KH2PO4 (0.6%) into the fermentation medium enhanced enzyme production while MgSO4.7H2O was found to inhabit microbial growth and glucose oxidase production by A. niger.
