During fermentation of sucrose by

An enzyme in yeast, a living organism, acts as a catalyst for the fermentation of glucose.

The fermentation of plant material (for example, barley and rice) is the route by which alcoholic drinks (e.g. beer, whiskey, gin and vodka) are produced. It is also how for biofuels is produced.

A 10-litre plastic container with tight-fitting lid will suffice as fermentation vessel.

Fermentation of sugarcane bagasse or sugars by

Fermentation analysis of the plant data under this program showed positive results. HPLC data showed a reduction of 44 percent in lactic acid concentration and a relative increase of 1.7 percent in ethanol yield, despite the drop in solids during the trial. Correcting it for solid loading, the relative increase in ethanol yield jumped to 2.7 percent (statistically significant as the data was processed at the 95 percent confidence level to ensure that the differences in the data are real). The rate of ethanol production (kinetics) followed a similar trend and the combination was able to increase the production rate by 5 percent at the height of fermentation.

Varied nutrient compositions improved cellulose fermentation conditions for C.

Syngas fermentation is a bioconversion technology of syngas/waste gas components to produce low-carbon biofuels. This technology is currently undergoing an intensive research and development phase. The fermentation process depends on the use of a microorganism called acetogen that generates acetate as a product of anaerobic repiration. Acetogens are found in a variety of habitats, generally those that are anaerobic. Acetogens can use a variety of compounds as sources of energy and carbon, the best-studied form of acetogenic metabolism involves the use of carbon dioxide as a carbon source and hydrogen as an energy source.

The Adh II appears to facilitate continuation of fermentation at high concentration of ethanol.


Amin148 has described ethanol fermentation in solid state by

Ethanol (CH3CH2OH) is a renewable fuel that can be made from various plant materials, collectively known as “.” Ethanol is an alcohol used as a blending agent with gasoline to increase octane and cut down carbon monoxide and other smog-causing emissions. The most common blend of ethanol is E10 (10% ethanol, 90% gasoline). Some vehicles, called , are designed to run on E85 (a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season), an alternative fuel with much higher ethanol content than regular gasoline. Roughly 97% of gasoline in the United States contains some ethanol. Today, most ethanol is made from plant starches and sugars, but scientists are continuing to develop technologies that would allow for the use of cellulose and hemicellulose, the non-edible fibrous material that constitutes the bulk of plant matter. In fact, several commercial-scale cellulosic ethanol biorefineries are currently operational in the United States. The common method for converting biomass into ethanol is called fermentation. During fermentation, microorganisms (e.g., bacteria and yeast) metabolize plant sugars and produce ethanol.
