Reports Summarize Ethanol Findings from W.X. Xu and Co-Authors (Continuous ethanol production from sugarcane molasses using a newly designed combined bioreactor system by immobilized Saccharomyces cerevisiae)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Ethanol. According to news originating from Guangdong, People's Republic of China, by NewsRx correspondents, research stated, "Continuous ethanol fermentation using polyvinyl alcohol (PVA), immobilized yeast, and sugarcane molasses (22 and 35 degrees Bx) with 8 g/L urea was run in a combined bioreactor system consisting of three-stage tubular bioreactors in series. The effect of the dilution rate (D) at 0.0037, 0.0075, 0.0117, 0.0145, 0.018, and 0.0282 H-1 on continuous ethanol fermentation was investigated in this study."

Our news journalists obtained a quote from the research, "The results showed that D had a significant effect on fermentation efficiency, sugar-utilized rate, ethanol yield, and ethanol productivity in this designed continuous fermentation system. The D had a linear relationship with residual sugar and ethanol production under certain conditions."

According to the news editors, the research concluded: "The highest fermentation efficiency of 83.26%, ethanol yield of 0.44 g/g, and the lowest residual sugar content of 6.50 g/L were achieved at 0.0037 H-1 in the fermentation of 22 degrees Bx molasses, indicating that the immobilization of cells using PVA, sugarcane pieces, and cotton towel is feasible and the established continuous system performs well."
