  1. Carbohydrate consumption (g/L) was calculated as Initial carbohydrate content (g/L) minus residual carbohydrate content (g/L). The carbohydrate utilization ratio was calculated using the following equation: Carbohydrate utilization ratio (w/w%) = Carbohydrate consumption (g/L)/Initial carbohydrate content (g/L) × 100%. The ethanol production ratio was calculated using the following equation: Ethanol production ratio (w/w%) = Ethanol yield (g/L)/Carbohydrate consumption (g/L) × 100%
