Producing Method of Bio-Ethanol by using sweet sorghum juice

摘要

The present invention relates to a method for manufacturing bioethanol, which comprises the steps of (a) preparing a medium by concentrating sweet sorghum juice; (b) obtaining a culture liquid by adding yeast to the medium to culture a starter; (c) separating the culture liquid into liquid and solid, collecting microbial cells obtained from the solid, and putting the microbial cells into a fermentation tank to obtain a fermented solution including ethanol; and (d) producing ethanol by conducting a process of distilling and dehydrating the fermented solution.
