Page: Acetogenesis
Acetogenesis the carbonic acids are converted to acetate, H{}2 and CO{}2. Just these substances can be changed directly into methane by methanogenic bacteria. This process is also called "anaerobic oxidation", because electrons in the form of H{}2 are released. The releasing of butyric ...

Page: Acetone, Butanol, Ethanol (ABE-) Fermentation
History ABE fermentation is one of the oldest known industrial fermentation with a history of more than 100 years. In 1861 butanol production through microbial fermentation was reported for the first time by Pasteur. This was followed by Schardinger in 1905 reporting production of acetone by fermentation ...

Page: Acidification
fragments of the hydrolysis are metabolized by facultative and fastidious anaerobes to carboxylic acids like acetic acid, propionic acid, butyric acid, valeric acid and hexane acid. In addition, they are metabolized to alcohol, hydrogen (H{}2) and carbon dioxide (CO{}2). There is a poor ...

Page: Biobutanol Processing
Butanol is an important bulk chemical with a wide range of possibilities for subsequent processing and use. Butanol has been produced almost exclusively via petrochemical ways since 1950. At that time common fermentation techniques were displaced because of low ...

primary crops, currently being used or considered for ethanol production can be categorised by agricultural and processrelated properties. The concentration of fermentable carbohydrates and other parameters in feedstocks, used for ethanol production are highly variable (see table 1). !General ethanol feedstock ...

Enzymes, necessary for hydrogen production  Hydrogen production has the simplest chemical reaction, catalyzed by enzymes. During this reaction, a reversible reduction of protons to molecular hydrogen occurs (compare reaction equation of molecular hydrogen production).  !hydrogen production.JPG! The necessary ...

Page: Bioethanol Processing
use and combustion of fossil fuels is responsible for 73 % of the CO{}2 production in the atmosphere and therefore extremely contributes to global warming, the interest in the development of methods, reducing green house gases, has been increased enormously. In order to control such emissions, many ...

Page: Bioethanol production of 2nd generation
Brazil, the production of bioethanol is based on sugar cane as feedstock, in the US and Europe, bioethanol is produced primarily from starch (cereal and corn). The European market in biofuels is expected to increase considerably in the near future. Within the next decade, a wider use of renewable ...

HISTORY{} In 1776 the Italian physicist and nature scientist Alessandro Volta discovered the appearance of methane at the anaerobic degradation of organic matter by connecting marsh gas in the mud of lakes and making combustion experiments. In 1821 the English physicist Michael Faraday identified methane ...
