Fermentation is the biochemical process in which energy is extracted from sugar without the use of oxygen. Fermentation can be performed by virtually all organisms, and some rely on it exclusively for their energy needs. Fermentation by yeast is the...

In its broadest sense, fermentation refers to any process by which large organic molecules are broken down to simpler molecules as the result of the action of microorganisms. The most familiar type of fermentation is the conversion of sugars and...

In the absence of the gas oxygen, certain living things are capable of breaking down carbohydrates (starches and sugars) to form alcohol and carbon dioxide gas. This process is known as anaerobic respiration or fermentation, and it has been used for...

Fermentation is a natural metabolic process that produces energy by breaking down carbohydrates (such as sugars) in the absence of oxygen. It occurs in many microorganisms (such as yeasts), and the end product can be either ethyl alcohol (ethanol) or...

Fermentation may mean: Fermentation (biochemistry), the process of energy production in a cell under anaerobic conditions (In a lack of oxygen) Fermentation (food), the conversion of carbohydrates into alcohols or acids under anaerobic conditions used...

The government awarded $385 million in grants last week aimed at jumpstarting ethanol production from nontraditional sources like wood chips, switchgrass and citrus peels. What's surprising is that half of the six projects chosen will use a process first discovered almost a century ago to...
