Enhanced production of reducing sugars from paragrass using microwave-assisted alkaline pretreatment

The main aims of this study were to examine the effectiveness of pretreatment methods for enhancing the conversion of Brachiara mutica (paragrass) lignocellulose into valuable reducing sugars by enzymatic hydrolysis. The pretreatments studied included alkali alone, microwave-assisted alkali, acid al...
