Description
Summary:Biochemical and chemical analyses of 'Bacterium (Bacteroides) melaninogenicum(s)' and subsequent black-pigmented Gram-negative anaerobes commenced from the initial isolation of 'B. melaninogenicus' in 1921 by Oliver and Wherry. The identity of the pigment remained contentious for several years until it was finally resolved by various chromatographic and spectroscopic methods. It soon became apparent that the species was heterogeneous, comprising both saccharolytic and asaccharolytic strains. Saccharolytic strains have now been placed in the genus Prevotella, and asaccharolytic species have been assigned to the genus Porphyromonas. The taxonomic positions of the very weakly fermentative species B. levii and B. macacae remain unresolved but there are indications that they may belong to the genus Porphyromonas.
