acidogeen

Acidogeen is a term occasionally used to describe a substance, organism, or process that produces acids. The term is not widely standardized in scientific literature and may be encountered as a transliteration or variation of "acidogen" or "acidogenic" used to refer to acid-producing agents or microorganisms.

Etymology and senses: the word is derived from the Latin acidus (acid) and the Greek-based suffix -gen indicating producers; in some languages it may be rendered as "acidogeen." In practice, acidogeen-like usage often refers to entities involved in acid production during fermentation or anaerobic metabolism.

Biological and chemical contexts: In microbiology, acidogenic organisms participate in fermentation where carbohydrates are converted to short-chain organic acids, such as lactate, acetate, propionate, and butyrate. In anaerobic digestion, the early stage called acidogenesis yields volatile fatty acids, hydrogen, and carbon dioxide. The acid production lowers pH and influences the progression to subsequent steps such as acetogenesis and methanogenesis.

Industrial and environmental relevance: Understanding acidogenesis is important for food fermentation, where acid production preserves products and contributes to flavor and texture. In wastewater treatment and biogas production, controlling acidogenic activity is essential to maintain digester stability and optimize methane yield, as excessive acid buildup can inhibit downstream microbial groups.
