The Fermentation of Beet Sugar Syrup to Produce Bioethanol Fermentation of sugar or starch-containing substrates by yeast to produce ethanol for use as a liquid fuel has been an accepted technology for many years. ... Kenneth,A.,Leiper,... - 《Journal of the Institute of Brewing》 被引量:...
A separate role for water activity in the conversion of sugars to ethanol by two strains of yeast is identified. During fermentation of both single and mixed sugar substrates, the water activity was shown to remain constant during the logarithmic growth phase. This is despite the changes in ...
of alcohol in wine and beer cannot exceed approximately 16%. In order to produce beverages with higher concentrations of alcohol, the fermented products must be distilled (Wong). S. cerevisiae can grow on simple sugars or even on common table sugar. Saccharomyces yeast is also well ...

can bring out a broader palette of flavors and aromas than you'll get with cultured yeast. But even though cultured yeast may not produce wines as bombastic as the same wine made with indigenous yeast, it will speed up the fermentation while it's converting that sugar to alcohol while givin...
(Clay. et al.2020b, p. 11 ). Recent innovations in the dairy alternative sector also include the emerging categories of cell-based and fermentation-derived dairy, made using advanced bioengineering processes (Mendly-Zambo et al.2021). Although these alternatives are promising, they still face ...
The reduced intracellular level of various pentoses in the presence of glucose served as a basis for calculating the apparent affinity of baker's yeast for glucose uptake under aerobic and anaerobic conditions, as well as in the presence of 2,4-dinitrophenol. It was found that the apparent Mic...
