How is industrial alcohol produced?

Explanation

Industrial alcohol is the ethanol `(C_(2)H_(5)OH)`, produced in large scale, using the yeast, Saccharomyces cerevisiae. It is used for industrial, laboratory and fuel purposes Bacteria such as Zymomonas mobilis and Sarcina ventricula are also used in industrial production of alcohol.
The molasses, corn, potatoes and wood waste are the raw materials for the commercial production of industrial alcohol. During this process, the milling of feed stock, followed by the addition of dilute or fungal amylase from Aspergillus make the draw material to break down the starch into fermentable sugar. Yeast is then added to convert the sugars into ethanol. The concentration of alcohol in the brewing is 96%, which is distilled to obtain ethanol. The ethanol is used as biofuel an alternative or additive of gasoline.
