From: An environmentally friendly and productive process for bioethanol production from potato waste

Ethanol production from enzymatic hydrolysates by S. cerevisiae. The initial S. cerevisiae inoculation amount was 0.5 %. All the reactions were performed at 30 °C for 72 h. Three independent replicates were performed. Black bars represent glucose concentrations after enzymatic hydrolysis, hollow bars represent ethanol concentrations after fermentation by S. cerevisiae, and grey bars represent the remaining glucose concentrations after fermentation by S. cerevisiae
