Innovation in advanced processes for biofuels production: materials, mechanisms, and performances (part 1)
Integrated Hydrolysis-Fermentation of Sweet Potato for Bioethanol via Co-Culture of S. cerevisiae TISTR 5088 and Saccharolytic Mold Isolates
Short Introductive summary
Bioethanol is a promising renewable biofuel due to its high efficiency and ability to be produced from various agricultural materials. Sweet potato is an attractive substrate for ethanol production because it is rich in starch and widely cultivated. However, conventional production methods rely on costly commercial enzymes for starch breakdown. This study explores an alternative approach by using a microbial co-culture system, combining the ethanol-producing yeast Saccharomyces cerevisiae TISTR 5088 with the saccharolytic mold Amylomyces rouxii TISTR 3182. The mold naturally converts starch into fermentable sugars, while the yeast ferments these sugars into ethanol. By applying simultaneous saccharification and fermentation (SSF) and optimizing fermentation conditions, this research offers a cost-effective and efficient strategy for producing bioethanol from sweet potato without commercial enzyme supplementation.
