Abstract
THE presence of D-fucosamine (2-amino-2,6-dideoxy-D-galactose) in materials of bacterial origin1 was first established in 1958. This amino sugar was isolated from a lipo-polysaccharide obtained from Chromobacterium violaceum (N.C.T.C. 7917) and has been detected in a few other strains of Rhizobiaceae. D-Fucosamine2 has also been found in Bacillus cereus of the family Bacillaceae3. On the other hand, L-fucosamine (2-amino-2,6-dideoxy-L-galactose) has been obtained from the capsule of Diplococcus pneumoniae type V of the Lactobacillaceae4. This communication concerns the isolation of L-fucosamine from a mucopolysaccharide obtained from Citrobacter freundii 05 : H30 of the Enterobacteriaceae. Thus, L-fucosamine is found for the first time in a Gram-negative bacterium.
