Sentences with phrase «ethanol by fermentation»

Not exact matches

Fermentation is triggered by lactic acid bacteria — or lactobacilli — and yeasts, which use the carbohydrate fuels from the cereal grains to produce ethanol (alcohol), carbon dioxide, lactic acid and acetic acid.

After dissolving plant biomass by the novel solvent, carboxylate - type liquid zwitterion, hydrolysis and fermentation were consecutively carried out in one reaction pot for conversion into ethanol.

Together the two plants would produce, at best, 22 million gallons of ethanol a year by using sulfuric acid to break the lignocellulose bonds and then burning the leftover lignin to power fermentation of the cellulose into ethanol.

At a biofuels energy symposium hosted by the Institute of Medicine of the National Academies last week in Washington, D.C., professor Jerald Schnoor said corn ethanol production facilities require large quantities of high - purity water during the fermentation process.

Then the company used custom - designed microbes to produce the new fuels by fermentation from a conventional ethanol feedstock.

Mascoma has developed yeast that can be dropped into all cellulosic ethanol fermentation processes to increase yields by fermenting the full array of sugars present in cellulosic fermentations, and by secreting enzymes (cellulases and hemicellulases) that can improve hydrolysis yields.

Meats from feedlots can be given such things as corn, corn by - products (some is derived from high fructose corn syrup production and ethanol), barley, milo, wheat, and other grains and roughage that often consists of corn stalks, alfalfa, cottonseed meal, and premixes of chemical preservatives, antibiotics, and fermentation products.

Capturing the nearly pure stream of CO2 emitted from corn ethanol refinery fermentation processes is cheaper however, and footing the bill for the added costs associated with carbon capture can be further offset by taking advantage of the market for CO2 availed by EOR.

For example, starch from corn grown in the midwest has traditionally been the source of some of the ethanol used as a fuel additive in the U.S.. Another option for the conversion of cellulosic biomass, such as hemp stalks, to ethanol is their hydrolysis to sugar, followed by fermentation and removal of the produced ethanol by distillation.
