Fig. 2From: An environmentally friendly and productive process for bioethanol production from potato wasteThe viscosity changes (a) and the glucan conversions of high-gravity SPRs (b) during enzymatic hydrolysis. All the reactions were performed at 45 °C and 200 rpm for 8 h with an initial pH of 4.8. The concentration of SPRs in reaction system was 36 % (w/v). Three independent replicates were performed. Solid diamonds represent the control, hollow diamonds represent commercial pectinase, solid triangles represent enzymes derived from A. niger, solid squares represent T. reesei TX, hollow squares represent T. reesei T1, and solid circles represent P. oxalicum JUA10-1Back to article page
