ABSTRACT

Ethyl alcohol ( ethanol or alcohol ) can be produced from fermentation process using yeast as a microorganism and cane molasses as a substrate. Cane molasses, which contains 60-70 % total sugars, minerals and vitamins is good raw material for ethanol fermentation. Ethanol fermentation fenomenomn as a process in which chemical changes are brought about in an organic substrate such as cane molasses, throught the action of biochemical catalysts, called enzymes, elaborated by yeast as types of microrganism. The strain commonly used in ethanol fermentation is Saccharomyces cerevisiae. Process conditions and type of strains are very important factors in the performance of ethanol fermentation. This paper describes as review on the fermentation of ethanol using cane molasses as substrate in relationship to aspect of a raw materials, process technology, microorganism and quality of ethanol products.

Key words : Fermentation, ethanol, cane molasses
