Fig. 1: Differences in the metabolism of different classes of aromatic compounds by R. eutropha H16.
From: Lignin valorization to bioplastics with an aromatic hub metabolite-based autoregulation system
R. eutropha H16 cultivation in minimal medium supplemented with (a) (PHL), (b) (2-HBA), (c) (BA), (d) (3-HBA), (e) (4-HBA), (f) (GEA), g (PCA), h (VA), i (IVA), j (4-HBD), k (3,4-DHBD) or l (VAN). Cultures were sampled at the indicated time points to evaluate growth by OD600nm determination (using a cell-free blank) and to measure metabolite concentrations in the medium by HPLC-UVVIS. Error bars represent the standard deviation of three biological replicates. The data are the mean ± SD, n = 3. PHL phenol, BA benzoate, 3-HBA 3-hydroxybenzoic acid, 2-HBA salicylic acid, 4-HBA 4-hydroxybenzoic acid, GEA gentisic acid, PCA protocatechuic acid, VA vanillic acid, IVA isovanillic acid, 4-HBD 4-hydroxybenzaldehyde, 3,4-DHBD 3,4-dihydroxybenzaldehyde, VAN vanillin, OD600nm optical density, measured as absorbance at 600 nm. Source data are provided as a Source Data file.
