21Lactic fermentation — Fermentation Fer men*ta tion (f[ e]r m[e^]n*t[=a] sh[u^]n), n. [Cf. F. fermentation.] 1. The process of undergoing an effervescent change, as by the action of yeast; in a wider sense (Physiol. Chem.), the transformation of an organic substance… …
22Putrefactive fermentation — Fermentation Fer men*ta tion (f[ e]r m[e^]n*t[=a] sh[u^]n), n. [Cf. F. fermentation.] 1. The process of undergoing an effervescent change, as by the action of yeast; in a wider sense (Physiol. Chem.), the transformation of an organic substance… …
23Syngas fermentation — Syngas fermentation, also known as synthesis gas fermentation, is a microbial process. In this process, a mixture of hydrogen, carbon monoxide, and carbon dioxide, known as syngas, is used as carbon and energy sources, and then converted into… …
24Synthesegas-Fermentation — Synthesegas Fermentation, kurz auch Syngas Fermentation, ist ein mikrobiologischer Prozess, bei dem ein Synthesegas aus Kohlenmonoxid (CO), Wasserstoff (H2) und Kohlendioxid (CO2) als Energiequelle für die Fermentation genutzt wird.[1] Durch die… …
25Enteric fermentation — is fermentation that takes place in the digestive systems of ruminant animals.It is one of the factors in increased methane emissions. Ruminant animals are those that have a rumen. A rumen is a special stomach found in cows, sheep, and water… …
26Dark fermentation — is the fermentative conversion of organic substrate to biohydrogen. It is a complex process manifested by diverse group of bacteria by a series of biochemical reactions involving three steps similar to anaerobic conversion. Dark fermentation… …
27Greenhouse gas — Simple diagram of greenhouse effect. A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] …
28intestinal gas — Volatile material (mostly swallowed air, partly digestive by products) in the digestive tract, which normally contains 150–500 cc of gas. Air in the stomach is either belched out or passed to the intestines. Some of its oxygen is absorbed into… …
29Natural gas — For other uses, see Natural gas (disambiguation). Natural gas extraction by countries in cubic meters per year. Natural gas is a naturally occurring gas mixture consisting primarily of methane, typically with 0–20% higher hydrocarbons[1] …
30Stickland fermentation — is the name for a chemical reaction that involves the coupled oxidation and reduction of amino acids to organic acids. The electron donor amino acid is oxidised to a volatile carboxylic acid one carbon atom shorter than the original amino acid.… …
