Abstract

Xylitol is a five-carbon sugar alcohol that has attracted great attention because of its potential uses as a natural sweetener, in dental care and as a sugar substitute in diet. In current scenario agricultural wastes are being undervalued, this study focuses on increasing the value addition and usage of agricultural waste. The present study aims to bring about a value addition to bagasse by converting it to a five sugar alcohol (xylitol). In present work, the bioconversion of crude xylose from plant biomass (bagasse) with help of Aspergillus niger is performed. The obtained biomass was first autoclaved for 20 min then subjected to acid hydrolysis. Following this, using Aspergillus niger fermentation process for 145 h was carried out. After every 24 h, fermented sample was tested for the presence of xylitol and confirmed by thin layer chromatography. It was found that during first 24 h, the production of xylitol was nill. The next 24 h showed some presence of sugar alcohol. On testing the sample after 72 h, the presence of xylitol is observed.
