pre-treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and 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 decre
