water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production
