Summary of the mass flow during bioconversion of Pin and/or PDG from glucose (a), phenylalanine (b), cinnamic acid (c), <i>p</i>-coumaric acid (d), and leucine (e).
<p>The data shown in the figure indicate the initial amount (Arial Bold type) and the consumed amount (Arial italic type) of the substrates, the amount of metabolic flux of the substrates to the presented pathway (Arial italic with underline type) and the highest productions of the substrates (Times normal type). The unit is μmol/L for all present values. Values presented here are the mean of three replications with standard deviation. The values were calculated according to Eq (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0137066#pone.0137066.e001" target="_blank">1</a>). </p><p></p><p></p><p></p><p><mi>Δ</mi>C<mo>=</mo></p><p></p><p></p><p><mo>(</mo></p><p>C<mo>−</mo></p><p>C<mn>0</mn></p><p></p><mo>)</mo><p></p><mo>×</mo><mn>1000</mn><p></p><mi>M</mi><p></p><p></p><p></p><p></p>(1) <p></p> Where, the letters indicate the corresponding data of each substrate, specifically, △C is the highest amount (μmol/L) of the products during the bioconversion, C is the highest amount (mg/L) after the bioconversion, C<sub>0</sub> (mg/L) is the initial amount, and M (μg/μmol) is the molecular weight. The abbreviations in the figure mean glucose (Glu), leucine (Leu), phenylalanine (Phe), tyrosine (Tyr), cinnamic acid (Ca), <i>p</i>-Coumaric acid (pC), pinoresinol (Pin), and pinoresinol diglucoside (PDG).<p></p
