Application of Raman Spectroscopy to the Biooxidation Analysis of Sulfide Minerals

Figure 1

CLSM images of A. thiooxidans cells (2D) after biooxidation of eMPEs (first column) and eMCEs (second column) surfaces after 1 h (first line), 12 h (second), 24 h (third), and 120 h (fourth). Epifluorescence of exopolysaccharides (in green colour) and of lipids (in blue). An overlap of both epifluorescence images is presented in the low left side of each set of images.
