Enzymatic saccharification and ethanol fermentation of agarose from red sea weed

摘要

The present invention relates to a process for producing ethanol by saccharification and fermentation using an agarase and a fermenting microorganism after dissolving an agar using an organic acid in order to effectively sacrifice a red alga agar to produce bioethanol, After pretreatment with an organic acid, acetic acid, Saccharophagus degradans and Agarase of Streptomyces coelicolor A3 were saccharified using NABH, and the saccharide was digested with fermentation strain Saccharomyces cerevisiae It is fermented through Saccharomyces cerevisia D5A to produce ethanol.
