Acidogenesis - Wikipedia
网页Acidogenesis is the second stage in the four stages of anaerobic digestion: Hydrolysis: A chemical reaction where particulates are solubilized and large polymers converted into simpler monomers; Acidogenesis: A biological reaction where simple monomers are converted into volatile fatty acids;
Acidogenesis - an overview | ScienceDirect Topics
网页Acidogenesis is the step in which organic compounds are mainly converted into VFAs during microbiological processes. The conversion of organic compounds into acetate and butyrate is accompanied by hydrogen formation. This involves hydrogenases and therefore the trace elements iron, nickel, zinc, and selenium are important (see Table 2).
Acidogenesis - an overview | ScienceDirect Topics
网页Acidogenesis is the fermentation stage where the products of hydrolysis (soluble organic monomers of sugars and amino acids) are degraded by acidogenic bacteria to produce alcohols, aldehydes, and volatile fatty acids (VFAs) and acetate together with H 2 and CO 2 (Sambusiti, 2013).
Acidogenic Fermentation - an overview | ScienceDirect Topics
网页The acidogenic fermentation is the initial phase of the anaerobic digestion of organic compounds to methane and carbon dioxide (i.e., biogas): soluble organic compounds are fermented into organic acids, such as acetic, propionic, butyric, and lactic acid, and other fermentation products, such as alcohols and hydrogen.
