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: Fermentation
Lignocellulosic biomass is hydrolyzed by explained treatments (mostly by acid treatment) (chapter "Hydrolysis of lignocellulosic biomass). The obtained hydrolysate (mixed sugarsolution) is then fermented by microorganisms (e.g. bacteria, yeast). This hydrolysate (mixed sugarsolution) often contains not only glucose, but also other ...

Page: Hydrogen from Biological Processes
Introduction In spite of increased utilization of energysaving technologies, the global energy consumption will rise dramatically in the next few years. Particularly, rapid industrialization of developing and threshold countries, as well as increasing global human population contribute to excess energy consumption. Fossil ...

Page: Hydrolysis of lignocellulosic biomass
Hydrolysis is a chemical process, where a molecule is cleaved into two parts by adding a molecule of water. One fragment of the molecule gains a hydrogen ion (H ). The other group collects the remaining hydroxyl group (OH − ). After pretreatment of lignocellulosic material, the cellulose ...

Page: Microorganisms for ABE fermentation
Microorganisms for ABE fermentation are especially sacchrolytic butyric acid producing clostridia. Clostridium acetobutylicum is the most popular and extensively implemented strain. Some other butanol producing strains are C. aurantibutyricum (produces acetone, isopropanol in addition to butanol), C. tetanomorphum ...

Emerging technology FischerTropsch Catalysis Synthesis gas (mixture of carbon monoxide and hydrogen), is converted into liquid hydrocarbons. This is the principle of the so called FischerTropsch synthesis. The process consists of three major steps: # Production of synthesis gas # FischerTropsch synthesis # Product processing ...

Page: Procedure of filling, continuity of procedure and after-digester
lowest efficiency of discontinuous modes features the batch mode. This kind of filling causes storageinduced nitrogen\ and methane deficits. The patchy fermentation wields a worse rate of yield and delay time towards continuous mode. This deficit can be weakened at the changecanmode, because ...

Page: Processing of lignocellulosic material to bioethanol
conversion of lignocellulosic material to monomeric sugars (e.g. C5 and C6 sugars) is more difficult than the conversion of starch. There are numerous features, which have to be considered additionally, compared to bioethanol production using sugar\ or starchbased feedstocks. One of them is an ...

Page: Status of world-wide ethanol production
growth in the fuel ethanol industry, which has taken place over recent years has been remarkable. Since 2000, dynamic and almost uncontrolled growth of ethanol supply and demand (led mainly by Brazil and the United States) has taken ...

Page: VFA
VOLATILE FATTY ACIDS (VFA) VFA´s or carbonic acids are metabolized during anaerobic fermentation. Acidification and acid degradation are in balance at a stable proceeding. An undersupply of the fermenter with substrate can cause a cutback of acidification and therefore of biogas production. If too much ...
