Abstract

Owing to the depletion of petroleum resources and the continuous emergence of environmental problems, lignocellulosic biomass, as a green, renewable, and environmentally friendly energy alternative, has attracted increasing attention to research its applications. Arabinans and arabinan-degrading enzymes have gained interest in plant biochemistry, food technology, and nutritional science. In this research, arabinase production using wheat bran as a carbon source and inducer by Aspergillus niger under solid-state fermentation was studied. The optimization of different fermentation parameters was performed by response surface methodology using superlative box design. Liquid-to-solid ratio, temperature, and pH were identified as more significant factors in enzyme production. The optimum conditions of liquid-to-solid ratio, temperature, and pH were found to be 7, 36°C, 4.5, respectively.
