Comparison of the ability of FTIR and O-PTIR to probe the metabolic heterogeneity within Bacillus strains producing PHB. (a) Score plot calculated from FTIR spectra acquired from bulk populations. (b) Score plot obtained from the O-PTIR signatures measured from individual bacterial cells; values in parentheses are the percentage of the total explained variance (TEV). (c) PC-1 loading plots from the O-PTIR (green) and FTIR (red) as well as the FTIR spectrum from commercial PHB (green, top). Plots are offset for clarity.
