Stomatococcus mucilaginosus produces a mannose-containing lipoglycan rather than lipoteichoic acid.

Five strains of Stomatococcus mucilaginosus were investigated to determine whether the organism produces a lipoteichoic acid or a lipoglycan. Crude phenol extracts were purified by hydrophobic interaction chromatography and shown to contain lipoglycan. The major carbohydrate component present was mannose, indicating that the macroamphiphile is a lipomannan. The fatty acid composition of the lipoglycan was similar to that of stomatococcal whole cells. These data provide additional chemotaxonomic evidence supporting the suprageneric classification of the genus Stomatococcus within a group of actinomycete genera that also includes the genus Micrococcus.
