The cell wall of Brevibacterium permense VKM Ac-2280 contains two teichoic acids. The major polymer represents a 1,6-poly(mannitol phosphate) substituted wirh either L-rhamnose (approximately 70%, unit A) or (S)-acetal of pyruvic acid (approximately 30%, unit B) with the overall chain length approximately 10 mannitol phosphate units. [carbohydrate structure: see text] The other polymer is an unsubstituted 1,3-poly(glycerol phosphate). The structures of the polymers were established using chemical degradations and NMR spectroscopy. The data obtained may be helpful in determination of the species-specific status of newly isolated Brevibacterium strains
