The cellulolytic efficiency of yeast isolates obtained from different fruit and fruit wastes was evaluated in terms of degradation of cellulose, release of reducing sugars and bioethanol production. The isolates CY-3, CY-4, CY-8 and CY-15 together with a reference cellulolytic strain Saccharomyces cerevisiae (NCIM 3220) displayed maximum hydrolysis of carboxy methyl cellulose (CMC) to yield reducing sugars when determined in 2 days interval for up to 22 days, Based on this, the isolates were further evaluated for combined saccharification and fermentation of a pretreated lignocellulosic substrate such as wheat straw in flask culture studies. | Isolation and evaluation of cellulolytic yeasts for production of ethanol from wheat straw
