Table 1. Influence of H2O2 Feeding Rate and Enzyme Concentration on a 100 mL Scalea.
| experiment | [AaeUPO] [μM] | [cyclohexane] [mM] | H2O2-feeding rate [mM h–1] | time [h] | total product concentration [mM] | productivity [g L–1 h–1] | turnover number (TN = molProduct × molrAaeUPO–1) |
|---|---|---|---|---|---|---|---|
| 1 | 10 | 500 | 50 | 24 | 70.7 | 0.3 | 7000 |
| 2 | 20 | 500 | 50 | 24 | 390 | 1.6 | 19,500 |
| 3 | 20 | 500 | 200 | 4 | 373 | 9.3 | 18,650 |
| 4 | 20 | 3 × 500 (0, 6, 28 h) | 20 | 24 | 269 | 1.1 | 13,450 |
Reaction conditions: [substrate] = 500 mM, [KPi, pH 6] = 100 mM, [ACN] = 50 vol %, [AaeUPO] = 10–20 μM, [H2O2-feeding rate] = 20–200 mM h–1 (4–17.6 M aqueous stock solution) starting volume 100 mL, 25 °C, 300 rpm, duplicate measurements. The detailed time courses are listed in the Supporting Information (Figures S1–S4).
