Composition of an unusual accessory polymer containing N-lactyl-3-amino-3,6-dideoxyhexose from walls of Bacillus megaterium NCIB 7581 Bishop, A. H. and White, P. J.,, 139, 2731-2738 (1993), doi = https://doi.org/10.1099/00221287-139-11-2731, publicationName = Microbiology Society, issn = 1350-0872, abstract= A polysaccharide of molecular mass at least 300000 Da was isolated from walls of Bacillus megaterium NCIB 7581. Three sugars, N-lactyl-3-amino-3,6-dideoxyhexose, N-acetylglucosamine and glucose were present in equimolar proportions, and accounted for 90% of the carbon of the polysaccharide. The remainder of the polymer was an unidentified acidic molecule, with a hydrophobic nature., language=, type=
