A Xylose consumed, xylitol produced and dry cell weight (DCW) of selected yeast mutant K2M and WT during fermentation using 5% w/v xylose, B batch fermentation profile of K2M, K21D and WT in bioreactor with 10% w/v xylose as carbon source for 72 h, C XR and XDH activities in K2M, K21D and WT whole cell extract, D growth profiles of strains K2M, K21D and WT in SD medium with 2% w/v d-glucose and 2% w/v d-xylose, respectively. The error bars represent the standard deviation of triplicate independent experiments performed
