Abstract
The oral actinomycete Rothia dentocariosa was investigated for the pre sence of the macroamphiphilic cell envelope component lipoteichoic aci d. Lipoteichoic acid of the conventional structure based on polyglycer ophosphate was not found but another lipocarbohydrate was recovered by phenol-water extraction and purified by hydrophobic interaction chrom atography. The lipocarbohydrate contained fatty acids similar to those of the whole cells. The major carbohydrate detected was mannose, alon g with minor amounts of glycerol. The lipocarbohydrate is therefore su ggested to be a lipomannan comparable to that produced by micrococcal species. This observation provides further chemotaxonomic support for the inclusion of the genus Rothia in the family Micrococcaceae.
