Figure 1

Mean fluorescence intensities (FI) for the different strains (wild type, gpd1Δ, gpd2Δ and gpd1Δgpd2Δ ) carrying either the multicopy (YEp)- or the integrative (YIp)- based GFP reporter. Fluorescence intensities are given in linear values. All values are normalized to the control strain TMB4120 carrying YEp-based GFP reporter. Acetoin was added at a concentration of 0.5 g/L.
