The biofilm and its extracellular polymeric substance (EPS) are known to respond to toxic chemicals. Shewanella oneidensis MR-1 wild-type (WT) and a hyper-adhesive mutant CP2-1-S1 (CP) are used as model organisms and Cr(VI) is selected as a toxic chemical in this study. We investigate the following the science questions: 1) what are the chemical differences revealed in molecular mapping between WT and CP; and 2) how WT and CP biofilms respond to a toxic chemical. The System for Analysis at the Liquid Vacuum Interface (SALVI) is employed for in situ chemical imaging of live biofilms using time-of-flight secondary ion mass spectrometry (ToF-SIMS). The SIMS spectra and principal component analysis (PCA) are used to study the biofilm spatial and chemical heterogeneity. In situ measurement of biofilm metabolic responses to toxic chemicals has been given for the first time. The method presented here is expected to be viable to study responses to other chemicals including antimicrobials in the context of antimicrobial resistance to biofilms with diverse applications.
