Abstract

Indiscriminate disposal of the solid waste generated from various agricultural practices cause detrimental effects on the environment. Utilization of the waste biomass for production of value-added products through biotechnological intervention not only helps to combat environmental pollution but also contributes significantly to the economy. In this study, a biofabrication software (fermentor tool) was applied to analyze statistics of xylanase production under solid non-sterile fermentation conditions. In solid substrate fermentation wheat bran, banana peel, millet waste, and sugarcane bagasse were evaluated. Maximal xylanase titer of 10545 U/g dry matter was obtained when wheat bran was used as a substrate (4 days incubation at 50 °C and pH value of 8.0). Partially purified xylanase was applied in saccharification of lignocellulosic materials to assess its potential application in a lignocellulosic biorefinery. In this context, the precision of predicted mathematical model was evaluated and fermentation provided a good prediction of the concentration of cell, substrate and product. Second, open non-sterilized fermentation method was established to save sterilization cost that seems to be a very economical and practically applicable to the enzyme industry.
