N2 - A solar reactor was designed to perform the conversion of starch to ethanol in a single step. An aqueous starch solution (5wt%) was fed into the reactor bed charged with Baker's yeast (Saccharomyces cerevisiae) and amylase, resulting in approximately 2.5wt% ethanol collected daily (ca. 25mLday-1). A significant amount of ethanol (38g) was collected over 63days, corresponding to 84% of the theoretical yield. The production of ethanol without additional energy input highlights the significance of this new process. The ethanol produced was also demonstrated as a potential fuel for direct ethanol fuel cells. Additionally, the secondary metabolite glycerol was fully reduced to a value-added product 1,3-propanediol, which is the first example of a fungal strain (Baker's yeast) converting glycerol insitu to 1,3-propanediol. All you need is sun: A solar reactor is designed for conversion of starch to bioethanol in a single step. An aqueous starch solution (5wt%) is fed into the reactor charged with Baker's yeast and amylase. Ethanol production with no additional energy input signifies the importance of this new process.
