Ethanol production by yeast cells immobilised in carrageenan gel beads and operated in a continuous tubular reactor reached 15 g dm−3 h−1 with a glucose feed of 165 g dm−3; a glucose residence period of 4.6 h was noted. The minimal cell loading to obtain uniform particles was 104...
THOUGH the knowledge of the existence of alcoholic fermentation and the preparation of alcoholic liquids dates back to very remote antiquity, it is only within comparatively recent times that an accurate acquaintance with the actual nature of the processes have been obtained. By the older writers ...
In the conventional alcoholic fermentation by yeasts of assimilable sugars at temperatures between 20 and 40 DEG C in a manner known per se, the pH is adjusted to between 2.7 and 4.0, and a yeast with, for example, the deposit number DSM 3649 is employed. It is also possible to employ ...
Ten yeast strains were selected to study the alcoholic fermentation of acid hydrolyzed cassava. The fermentation tests were done in 500 ml Erlenmeyer flasks with fermentation bungs and kept under stationary condition at 30 C, 37 C and 40 C. It was found that at 30 C, Saccharomyces pe'ka pro...
Process of fermentation has a long history, as even ancient Egyptians knew the secret of brewing the beer. Though fermentation itself had been used for thousands of years, it was considered to be a magical process, but not a logically explicable one. By the 17th century, role of ...
Temperature control is also carried out against alcohol ferment of a key. The main purpose is to release alcohol ferment energy for yeast metabolic requirements. However, surplus energy will be released to heat in the form of chutes, make fermentation temperatures rise. The optimal temperatures for...
Sake is classified as "brewed sake" when classified by production method. Sake is made from rice, rice malt, and water, and alcoholic fermentation is performed by the power of yeast. Sake is classified into eight types depending on the "rice polishing ratio" and whether or not "brewed alcoh...

Alcohol-free wines and beers are usually made the same way as normal wine and beer – but with an added step at the end that removes the alcohol. After fermentation is complete, and the desired amount of sugar has been converted to alcohol by the yeast, the wine is then distilled. ...
During the withering process we observed a succession of three yeast populations associated with grapes. A high degree of species biodiversity was detected the last day of the monitoring period. The dominance of Saccharomyces cerevisiae in the inoculated fermentation was confirmed.ConclusionsA succession ...
