title: Lipid Composition as a Guide to the Classification of Some Coryneform Bacteria-containing an A 4 α Type Peptidoglycan (Schleifer and Kandler).
abstract: Fatty acid, menaquinone and polar lipid analyses were performed on Artbrobacter nicotianae, A. citreus, Brevibacterium incertum, B. liquefaciens, B. protopbormiae, "B. sulfureum" and "B. fuscum". The results of the present study indicate A. nicotianae, B. liquefaciens, B. protopbormiae and "B. fuscum" are unrelated to the genus Artbrobacter sensu stricto and possibly warrant a new taxon. Strains labelled A. citreus were heterogeneous on the basis of lipid composition. The type strain of A. citreus (NCIB 8915) is a legitimate Artbrobacter species whereas strain ATCC 15170 was closely related to "B. sulfureum". Brevibacterium incertum differed from all of the other strains examined on the basis of lipid composition. The absence of menaquinones within B. incertum together with the presence of straight-chain saturated and monounsaturated (cis-vaccenic acid series) fatty acids indicates this taxon does not belong to the 'coryneform group of bacteria'.
