Definition

Noun

A gram-negative rod-shaped nonmotile chemoorganotroph and non-spore forming facultative anaerobic bacterium involved in succinic production.

Supplement

Actinobacillus succinogenes has a size of about 0.63 by 1.21 micrometers wherein in culture media formed grey, circular and translucent colonies which grows best at pH ranging from 6.0-7.4 with a temperature of 37’C. It is known to be capnophilic and grows better in a condition with high carbon dioxide. In an enrichment cultures it produces acetic acid, succinic acid, formic acid and some by products.

Actinobacillus succinogenes isolated from the rumen of bovine which is non spore forming and fermentative and it uses phosphoenolpyruvate to generate succinate where it able to generates low-redox potential electrons. It is able to produced succinic acid that is useful to for food and pharmaceutical products, detergents, surfactants, green solvents, biodegradable plastics and ingredients to stimulate plant and animal growth.

Actinobacillus succinogenes is oxidase, catalase, alkaline phosphatase and beta-galactosidase positive. In succinate fermentation it fixed carbon dioxide into succinate during glucose fermentation which contributes to a cleaner environment.
