Chemical ionization GC/MS determinations of anthrose and rhamnose levels in wild-type and mutant spores. Chromatograms were produced using 108 spores of the indicated strains. TMS derivatives of methyl glycosides were analyzed using selected ion monitoring of m/z 363 for rhamnose and m/z 404 for anthrose. Note that two peaks are obtained for each sugar (in sugar-specific ratios) due to the alpha and beta forms of their methyl glycosides.
