Streptomyces species with madurose (3-O-methyl-D-galactose) as a whole-cell sugar.
Madurose, an actinomycete whole-cell sugar, was found in the strains of the genus Streptomyces: three strains of S. platensis, one strain each of S. platensis subsp. malvinus, and S. albus subsp. albus. The sugar was isolated from the hydrolysate of S. platensis IFO 14008 cells, and was identified as madurose (3-O-methyl-D-galactose) by chromatographic analyses, 1H-NMR spectrometry, mass spectrometry as its alditol acetate, and demethylation with boron trichloride. Cell walls of the strain contained peptidoglycan and teichoic acids. LL-Diaminopimelic acid, glycine, glutamic acid, and alanine were present in the peptidoglycan fraction in molar ratios of 1.0:1.3:1.2:2.3. Madurose was detected in the teichoic acid fraction, which was composed of phosphorus, glycerol, galactose, and madurose in molar ratios of 9.3:8.5:2.9:1.0. Thus, madurose was found in the glycerol teichoic acid moiety of the cell walls of this strain.
