The structures of two teichoic acid fractions (TA1 and TA2) isolated from the thermophilic Gram-positive bacterium Geobacillus thermoleovorans strain Fango were investigated by means of chemical and NMR spectroscopic methods. The most abundant species (TA1) exhibited a rather regular structure comprising two different repeating units of 1,3-glycerol phosphate nonstoichiometrically substituted by terminal-α-d-Galp (t-α-d-Galp). The second molecular species (TA2) presented a higher structural variability and t-α-d-Glcp and the disaccharides t-α-d-GlcpNAc-(1→2)-α-d-Glcp and t-α-d-GlcpNAc-(1→3)-α-d-Glcp were also present as minor substituents at O-2 of the glycerol phosphate residues. Minor substitution by alanine could also be detected.
