PCA analysis of intracellular metabolites for S. aureus 10943 and 6538 biofilm and planktonic cultures results in statistical clustering of biofilm phenotype. PCA analysis of intracellular metabolites in S. aureus 10943 and 6538 biofilm and planktonic cultures detected by 1D 1H NMR separates the biofilm phenotype into a single quadrant of the 2D PCA scores plot as a result of significant statistical separations from S. aureus 6538 planktonic cultures along PC1 and from S. aureus 10943 planktonic cultures along PC2.
