  2. Acetone–butanol–ethanol fermentation - Wikipedia

    en.wikipedia.org/wiki/Acetone–butanol–ethanol...

    The process may be likened to how yeast ferments sugars to produce ethanol for wine, beer, or fuel, but the organisms that carry out the ABE fermentation are strictly anaerobic (obligate anaerobes). The ABE fermentation produces solvents in a ratio of 3 parts acetone, 6 parts butanol to 1 part ethanol.

  3. Application of biofilms in industry - Wikipedia

    en.wikipedia.org/wiki/Application_of_biofilms_in...

    One method for treating dairy wastewater is using anaerobic biofilm reactors. The biofilm grows on a support material which can be made of seashell, natural stones, charcoal, and plastic materials, amongst other sources. These anaerobic filters, however, can be clogged due to the high fat content of dairy wastewater. To combat the accumulation ...

  4. Anaerobic digestion - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_digestion

    The most important initial issue when considering the application of anaerobic digestion systems is the feedstock to the process. [55] Almost any organic material can be processed with anaerobic digestion; [ 56 ] however, if biogas production is the aim, the level of putrescibility is the key factor in its successful application. [ 57 ]

  5. Digestate - Wikipedia

    en.wikipedia.org/wiki/Digestate

    Anaerobic digestion is a versatile process that can use many different types of feedstocks. Example of feedstocks can be from: Sewage sludges: Liquid sludge, untreated sewage sludge, composted sludge, and lime treated sludge.

  6. Denitrification - Wikipedia

    en.wikipedia.org/wiki/Denitrification

    Terminal electron acceptor is a compound that gets reduced in the reaction by receiving electrons. Examples of anoxic environments can include soils, [11] groundwater, [12] wetlands, oil reservoirs, [13] poorly ventilated corners of the ocean and seafloor sediments. Furthermore, denitrification can occur in oxic environments as well.

  7. Anaerobic respiration - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_respiration

    Anaerobic cellular respiration and fermentation generate ATP in very different ways, and the terms should not be treated as synonyms. Cellular respiration (both aerobic and anaerobic) uses highly reduced chemical compounds such as NADH and FADH 2 (for example produced during glycolysis and the citric acid cycle) to establish an electrochemical gradient (often a proton gradient) across a membrane.

  8. Alkylbenzene sulfonate - Wikipedia

    en.wikipedia.org/wiki/Alkylbenzene_sulfonate

    As such, BAS was phased out of most detergent products during the 1960s, being replaced with linear alkylbenzene sulfonates (LAS), which biodegrade much more rapidly. BAS is still important in certain agrochemical and industrial applications, where rapid biodegradability is of reduced importance.

  9. Primary nutritional groups - Wikipedia

    en.wikipedia.org/wiki/Primary_nutritional_groups

    The terms aerobic respiration, anaerobic respiration and fermentation (substrate-level phosphorylation) do not refer to primary nutritional groups, but simply reflect the different use of possible electron acceptors in particular organisms, such as O 2 in aerobic respiration, or nitrate (NO − 3), sulfate (SO 2−
