Resumen de "Pseudomonas fluorescens" SBW25 Biofilm and Planktonic Cells Have Differentiable Raman Spectral Profiles

Wei E. Huang, Susanne Ude, Andrew J. Spiers

• Biofilms, and other bacterial aggregations, are of significance in both environmental microbiology and in plant and human pathogenesis. Comparative single-cell Raman spectral analysis can differentiate between planktonic bacteria and those recovered from biofilms and appears to offer a new means by which to investigate bacterial cell physiology, metabolic status, and stress under different environmental conditions.
