Fig. 2From: Metabolic changes associated with adaptive resistance to daptomycin in Streptococcus mitis-oralisThe PCA scores plot was generated from 1D 1H NMR spectra collected using cell-free lysates of S. mitis-oralis strains 351 (blue) and 351-D10 (red) cultivated in BHI with 2 g/L of supplemental 13C-glucose and harvested at 2 h (351) or 2 h 45 min (351-D10). The R2 and Q2 are 0.931 and 0.781 respectively for the PCA modelBack to article page
