The production of butanol by biological means was first performed by Louis Pasteur in 1861. [5] In 1905, Austrian biochemist Franz Schardinger found that acetone could similarly be produced. [5] In 1910 Auguste Fernbach (1860–1939) developed a bacterial fermentation process using potato starch as a feedstock in the production of butanol. [6]
Acetone, butanol, and ethanol are the most common products of solventogenesis. Some species such as Clostridium beijerinckii, Clostridium puniceum and Clostridium roseum are able to further reduce acetone to isopropanol. Several species are able to produce additional solvents under various culture conditions.
In ethanol fermentation, one glucose molecule is converted into two ethanol molecules and two carbon dioxide (CO 2) molecules. [10] [11] It is used to make bread dough rise: the carbon dioxide forms bubbles, expanding the dough into a foam. [12] [13] The ethanol is the intoxicating agent in alcoholic beverages such as wine, beer and liquor. [14]
A senior lecturer at the University of Manchester, England, he used them in 1916 as a bio-chemical tool to produce at the same time, jointly, acetone, ethanol, and n-butanol from starch. The method has been described since as the ABE process , (Acetone Butanol Ethanol fermentation process), yielding 3 parts of acetone , 6 of n -butanol, and 1 ...
Fermentation is a biochemical process during which yeast and certain bacteria convert sugars to ethanol, carbon dioxide, as well as other metabolic byproducts. [ 73 ] [ 74 ] The average human digestive system produces approximately 3 g of ethanol per day through fermentation of its contents. [ 75 ]
Nearly one in five, or 20%, of the more than 9.2 million impacted workers reside in households below the poverty line, while nearly half, or almost 49%, have family incomes below twice the poverty ...
Carbon dioxide is cogenerated. Like ethanol, butanol can be produced by fermentation processes. Saccharomyces yeast are known to produce these higher alcohols at temperatures above 75 °F (24 °C). The bacterium Clostridium acetobutylicum can feed on cellulose (also an alcohol) to produce butanol on an industrial scale. [34]
