Additional file 10 of Response and oil degradation activities of a northeast Atlantic bacterial community to biogenic and synthetic surfactants

Additional file 9: Supplementary Figure S6. Differences in aliphatic and polycyclic aromatic hydrocarbon biomarker ratios of three different treatments amended with crude oil: BEWAF (seawater, crude oil, and biosurfactant), CEWAF (seawater, crude oil, and synthetic dispersant), and WAF (seawater and crude oil only), over time in days (grey boxes): nC17/pristane (nC17/pri), nC18/phytane (nC18/phy), Phenanthrene/9-methylphenanthrene (P/9MP), (3+2)-methylphenanthrene/(9+1)-mehylphenanthrene (3+2MP/9+1MP), and 3-methylphenanthrene/9-methylphenanthrene (3MP/9MP). Values are the mean of three independent replicates (except for BEWAF day 0 (two replicates) and CEWAF day 28 (one replicate)) +/- standard deviation.
