Practical and theoretical considerations in the production of high concentrations of alcohol by fermentation

Impact of Deficit Irrigation on Sorghum Physical and Chemical Properties and Ethanol Yield

“…Fermentation efficiencies were calculated as the actual ethanol yield divided by the theoretical ethanol yield. The theoretical ethanol yield was determined using the total starch contents in the samples, assuming 0.5672 g ethanol from 1 g of starch (Thomas et al, 1996).…”

Optimization of Nitrogen and Metal Ions Supplementation for Very High Gravity Bioethanol Fermentation from Sweet Sorghum Juice Using an Orthogonal Array Design

“…However, under appropriate environmental and nutritional conditions, Saccharomyces cerevisiae can produce and tolerate high ethanol concentrations [9]. The yeast is well-known as the main ethanol-producing microorganism used in industrial processes [10].…”

Energy-saving direct ethanol production from viscosity reduction mash of sweet potato at very high gravity (VHG)

“…The technology involves the preparation and fermentation of mash containing high dissolved solids (N300 g/L) to yield a high ethanol concentration [10]. It is of interest for fuel ethanol production because of its potential to increase fermentor throughput, reduce processing costs, reduce energy cost per liter of ethanol and the risk of bacterial contamination [11]. VHG technology has been intensively conducted in ethanol production from cereal grains because of their low viscous nature; however, its application on roots and tubers has been rarely reported.…”
