[Utilization of 3-chlorobenzoic acid by Acinetobacter calcoaceticus]. 1985

G M Zaitsev, and B P Baskunov

A strain of Acinetobacter calcoaceticus assimilating 3-chlorobenzoic acid (3-CBA) as a sole source of carbon and energy was isolated from soil near Moscow. When 3-CBA is utilized, 2-chloro-cis, cis-muconic acid is accumulated in the medium. The liberation of chlorine atoms is 50--60% of the theoretically possible value. The oxidation of 3-CBA yields 3-chloropyrocatechol (3-CPC) and 4-chloropyrocatechol (4-CPC). 4-CPC serves as a source of nutrition for A. calcoaceticus. The oxidation of 3-CPC yields 2-chloro-cis, cis-muconic acid which is accumulated in the cultural broth without further utilization. The enzyme system of 3-CBA is inducible.

UI	MeSH Term	Description	Entries
D010084	Oxidation-Reduction	A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).	Redox,Oxidation Reduction
D002621	Chemistry	A basic science concerned with the composition, structure, and properties of matter; and the reactions that occur between substances and the associated energy exchange.
