    A surface spectroscopy study of a Pseudomonas fluorescens biofilm in the presence of an immobilized air bubble
    (Elsevier, 2019-05-28) Lefèvre, Thierry; Greener, Jesse; Abbaszadeh Amirdehi, Mehran; Pousti, Mohammad
    A linear spectral mapping technique was applied to monitor the growth of biomolecular absorption bands at the bio-interface of a nascent Pseudomonas fluorescens biofilm during and after interaction with a surface-adhered air bubble. Attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectra were obtained in different locations in a microchannel with adequate spatial and temporal resolution to study the effect of a static bubble on the evolution of protein and lipid signals at the ATR crystal surface. The results reveal that the presence of a bubble during the lag phase modified levels of extracellular lipids and affected a surface restructuring process, many hours after the bubble's disappearance.
