untargeted metabolomics which allows for broad metabolome coverage. For this reason, we
used high-performance liquid chromatography interfaced to high-resolution mass
spectrometry (HPLC/HRMS). As an alternative to standard microscopy techniques, we
introduced pioneering Coherent Anti-stokes Raman Scattering Microscopy (CARS) to non-
invasively visualize microbial cells. Brick samples saturated with salt solution (KCl, NaCl …
