Methods to Improve Alcohol Fermentation Process: A Review

Abstract

Biofuel has been a hot research topic in the 21st century because it is promising to gradually replace today’s traditional
fuel in the future, which can protect the earth from many aspects. For example, biofuel’s biodegradability can reduce
pollution and solve the problem of the energy crisis to a certain extent. This paper mainly takes ethanol fuel as the
research object focuses on the mechanism of yeast production of biofuel, different production methods, and benefits of
yeast, and discusses the future of isobutanol, a more efficient biofuel with more significant potential.
