Utilization of concentrate after membrane filtration of sugar beet thin juice for ethanol production

Repeated ethanol production from sweet sorghum juice concentrated by membrane separation

“…100% theoretical ethanol yield corresponds to 0.538 for sucrose and 0.511 for glucose and fructose (Kawa-Rygielska et al, 2013).…”

Utilization of spent brewer’s yeast for supplementation of distillery corn mashes

“…Then 200 g of mashes were transferred to 300 mL conical fl asks and sealed with silicone stoppers with attached fermentation tube and sampling port as described previously 4 . The fl asks were placed in a Type 357 water bath shaker (Elpin+, Poland) at 30°C and 50 rpm agitation speed for 72 h. Both mashing and fermentation experiments were performed in duplicate.…”

Production of ethanol from raw juice and thick juice of sugar beet by continuous ethanol fermentation with flocculating yeast strain KF-7

“…Dodic et al [5] and Grahovac et al [12] reported that based on the fermentation rate, ethanol concentration, and sugar consumption, an initial sugar concentration of approximately 200 g L À1 is the optimal for the fermentation of thick juice. Additionally, Dziugan et al [7] and Kawa-Rygielska et al [13] reported that supplementing the thick juice or thin juice with fermentation nutrients accelerated ethanol fermentation and improved the final ethanol concentration. Previous studies have found that flocculating yeast strain was suitable for developing efficient bioprocesses to produce ethanol from sugar beet [9,14].…”
