Comparison of WTA structure distribution of 8 S. aureus strains grown in (A) TSB and (B) SATA media. The structures were determined by HPAEC-PAD carbotyping directly from cell growth in the same HPAEC-PAD analysis. The proportion of WTA structures in each strain (calculated as percentage) was determined from single experiments and calculated from peak areas using the formulas described in the Supplementary Methods.
