| Abstract: | The cell walls of Microbispora mesophila strain Ac-1953T (the family Streptosporangiaceae) and Thermobifida fusca Ac-1952T (the family Nocardiopsaceae) were found to contain teichoic acids of a poly(glycerol phosphate) nature. The teichoic acid of M. mesophila (formerly Thermomonospora mesophila) represents a 1,3-poly(glycerol phosphate) containing 5% of substituent 2-acetamido-2-deoxy- -D-galactosaminyl residues. Teichoic acid of such a kind was found in actinomycetes for the first time. The cell wall of T. fusca (formerly Thermonospora fusca) contains two teichoic acids, namely, unsubstituted 1,3-poly(glycerol phosphate) and  -glucosylated 1,3-poly(glycerol phosphate). |
