  1. Yields are based on dilution/ evaporation corrected concentrations to account for actual substrate utilization
  2. aTotal aromatics titer is comprised of pABA, PEA, pHBA and tryptophol
  3. bCarbon yields of PEA and total aromatics were estimated to reflect only the de novo synthesized fraction
