Regarding the production process, corn-based ethanol has several differences when compared to sugarcane-based ethanol (Fig. 1 A and B).First, corn energy storage is mainly in the form of starch, a polymer composed of d-glucose units, which is not directly used by S. cerevisiae, requiring a hydrolytic pretreatment step prior to fermentation.The process could operate via two different types of ...
Alcoholic Fermentation
Alcoholic fermentation is an anaerobic process carried on by living yeast cells. The cells absorb the simple sugars, which in turn, are broken down in a series of successive changes in which action by oxidizing and reducing enzymes within the cell takes place. The final result is the formation of ethyl alcohol and carbon dioxide accompanied by ...
Alcoholic Fermentation
The redox balance of alcoholic fermentation is achieved by the regeneration of NAD + during the reduction of acetaldehyde to ethanol, which is catalyzed by alcohol deydrogenase. The ATP yield of alcoholic fermentation is 1 or 2 mol of ATP per mole of glucose oxidized via the ED and EMP pathways, respectively.Zymomonas mobilis is the most important bacterial species that is able to perform ...
Fermentation
Fermentation is a well-known natural process that has been used by humanity for thousands of years, with the fundamental purpose of making alcoholic beverages such as wine, and also other non-alcoholic products. From a strictly biochemical point of view, fermentation is a process of central metabolism in which an organism converts a carbohydrate, such as starch or sugar, into an alcohol or an ...
Why, when, and how did yeast evolve alcoholic fermentation?
The strengthened glycolytic flow had in parallel a beneficial effect on the microbial competition outcome and later evolved as a "new" tool promoting the yeast competition ability under aerobic conditions. The basic aerobic alcoholic fermentation ability was subsequently "upgraded" in several lineages by evolving additional regulatory steps ...

Alcoholic fermentation is the base for the manufacturing of alcoholic beverages like beer and wine ...
The most common microorganism used in industries for alcoholic fermentation is the yeast Saccharomyces cerevisiae. A curious fact about alcoholic fermentation is that the production of CO 2 gas during alcoholic fermentation is what gave this process its name. The word "fermentation" comes from the Latin word "fervere," which means boiling.
The Role of Yeasts in Fermentation Processes
1.2. Non-Saccharomyces YeastsNon-Saccharomyces yeasts are a group of microorganisms used in numerous fermentation processes, since their high metabolic differences allow the synthesis of different final products.Generally, many of these yeasts capable of modifying the sensory quality of wines are considered as contaminants, so eliminating them or keeping them at low levels was a basic ...
