THE OXIDATION OF ETHANOL AND TRICARBOXYLIC ACID CYCLE INTERMEDIATES BY ACETOBACTER PEROXYDANS

The oxidation of ethanol and tricarboxylic acid cycle intermediates by Acetobacter peroxydans.

The main taxonomic characteristic of the genus Acetobacter as presently described is the ability to oxidize ethanol to acetic acid (Breed et al., 1948), although some species carry the oxidation further. Of particular interest is the demonstration that Acetobacter aceti produces citrate when supplied acetate and intermediates of the TCA2 cycle (Antoniani et al., 1950). This species thus appears...

Tricarboxylic acid cycle activity in Acetobacter pasteurianum.

Previous papers from this laboratory (King and Cheldelin, 1952, 1952a, 1954; Hauge et al., 1955, 1955a) have reported on the oxidation of carbohydrates in Acetobacter suboxydans. Neither resting nor disintegrated cells can oxidize acetate or other intermediates of the tricarboxylic acid cycle. These findings have recently been confirmed in another laboratory (Rao and Gunsalus, 1955). From the c...

Oxidation of Intermediates of the Tricarboxylic Acid Cycle by Extracts of Azotobacter Agile.

Oxidation of fatty acids and tricarboxylic acid cycle intermediates by isolated rat liver mitochondria.

Beginning with the fundamental observation of Warburg in 1913 (1) it has been a general finding that the more highly organized enzyme systems of animal tissues responsible for oxidation of metabolites by molecular oxygen are associated with the insoluble particulate portion of the cell. Among the several approaches which have been used to study the morphology and composition of such catalytical...

The oxidation of tricarboxylic acid cycle compounds by Penicillium chrysogenum.

The presence of a tricarboxylic acid cycle in Penicillium chry8ogenum, as yet, has not been demonstrated conclusively. Ajl (1951) stated that of the mechanisms proposed for oxidation of the 2 carbon fragment in mold metabolism, the evidence for a tricarboxylic acid cycle is the least convincing. This paper presents a study of some of the enzymes of the tricarboxylic acid cycle in cell-free prep...
