Abstract: A method to produce a fermentation product comprising: providing a biomass material; pretreating the biomass material by contacting the biomass material with a solution containing at least one alpha-hydroxysulfonic acid to produce a pretreated biomass mixture containing at least one fermentable sugar; adding one or more saccharification enzymes to the pretreated biomass mixture, wherein the pretreated biomass mixture has a suitable condition for the one or more saccharification enzymes; performing enzymatic hydrolysis of cellulose by the one or more saccharification enzymes for greater than 24 hours to generate a hydrolysate; and adding at least one fermentation microorganism to the hydrolysate under a suitable condition for simultaneous saccharification and fermentation.
