Fermentation is one of several methods in alcohol fermentation,
biochemical activities of microorganisms is usually used under anaerobic condition (Bailey and Ollis,1997). During
fermentation, feedstock changed to alcohol. Sucrose content of
feedstock is broken down to glucose, and glucose fermentation
produces alcohol [Prentis,1990]. Basically, fermented alcohol
comes from glucose conversion. The yeast Saccharomyces
serevisiae is usually used as supporting microbes for
fermentation.
