ABSTRACT

Industrially important xylanase enzyme production was explored by using fungal strain isolated from litter degrading soil. Aspergillus nidulans isolated from litter soil was grown on rice bran as solid substrate to produce xylanase. Various growth factors were optimized to optimize enzyme production. In the present study, Aspergillus nidulans showed a higher enzyme production of 561.75 U/g when grown on rice bran under optimized conditions of temperature, moisture content, incubation period, size and age of inoculum.
