Fig. 6: Detection of the differences of the colonization of UV-exposed polymer by colony forming units.
From: Photo-oxidation of PE-HD affecting polymer/fuel interaction and bacterial attachment
Adhered cells in percentage as determined by CFU for to PE-HD1 and PE-HD2 exposed to different UV-radiative exposures H. Black bars represent B. subtilis, shaded bars represent P. aeruginosa cells, respectively, adhered to either non-exposed PE-HD1 (gray background) or non-exposed PE-HD2 (white background) or PE-HD1 and PE-HD2 that were previously exposed to different UV-radiative exposures H of 217 MJ m−2 and 500 MJ m−2, respectively. Standard error of the mean of nine replicates. Significant differences in adherence of bacterial cells are indicated with a star; p = 0.05.
