Lignocellulosic biomass is an attractive resource for the production of ethanol because of its abundance and lower cost. The economics of lignocellulosic ethanol production can be improved by enhancing the ethanol titres along with the utilisation of waste generated during the bioconversion process.

The present study was aimed at the development of a bioconversion process for producing a high concentration of ethanol from alkali-treated cellulose-rich wheat straw (WS) and utilization of unused hemicellulosic fraction into value added products.

WS was subjected to microwave-assisted alkali (MAA) treatment. Scanning electron microscopy and Fourier transform infrared spectroscopy were used to analyse structural changes in untreated and pretreated WS. Bioethanol production from pretreated WS was carried out by pre hydrolysis and simultaneous saccharification and …
