The potential of sweet potato biorefinery and development of alternative uses.

The bioethanol production from the sweet potato variety BRS Cuia using three different strains of (LPB1-93, ATCC-26602, and CA-11) was carried out in this research Comparative analyses of consumed sugar, ethanol yield, and productivity (in tons per hectare) increased along with the concentration of cells in the inoculum. Additionally, to verify the aromatic quality of a potential sweet potato distilled spirit, volatile organic compounds were analyzed. The results showed a yield of over 90% ethanol.
