Production of 2-PE by resting cells in the presence of Ehrlich pathway intermediates: l-phenylalanine (l-Phe), phenylacetaldehyde (PA) or phenylpyruvate (PP). CM12-5 (pPE-1) (blue bars) and CM12-5Δgcd (xylABE) (pPE-1) (red bars) cells were grown in the presence of glucose as the C source until reaching a DO₆₆₀ of 1, the cultures were then washed and concentrated in 1xM9 + 0.5% (w/v) glucose or xylose to reach a DO₆₆₀ of about 10, and the effect of 1 mM l-Phe PA or PP supplements on 2-PE production was measured after 24 h of incubation. The figure shows the average values of three independent assays
