A Anaerobic vanillate O-demethylation in A. woodii in the presence of CO₂. 10 mM vanillate is converted into 10 mM PCA and 7.5 mM acetate. B The difference of ADP1 growth on 10 mM vanillate and on mixture containing 10 mM PCA and 7.5 mM acetate in aerobic conditions. The mixture represents the end products of vanillate O-demethylation and subsequent processing of the methyl group in the Wood–Ljungdahl pathway by A. woodii. The error bars indicate the standard deviations from the average values of the biologically independent triplicates. In some cases, the error bars are smaller than the size of the marker
