Reclassification of Brevibacterium leucinophagum Kinney and Werkman as a Gram-Negative Organism, Probably in the Genus Acinetobacter

A study of the tricarboxylic acid cycle enzymes of Brevibacterium leucinophagum ATCC 13809, the type strain of this species, together with morphological, physiological, and electron microscopy studies indicated that, contrary to its present classification, B. leucinophagum is gram negative and probably is better classified in the genus Acinetobacter.
