Fig. 6: Production of vanillin arabinopyranoside with and without pH control.

The initial donor/acceptor balance was 2/1 (mole/mole) and the acceptor conversion (%) over time was determined by HPLC at different time intervals for 16 h. Yield profiles are represented by a dashed line and black circles for non-controlled pH and by a continuous line and white circles for controlled pH. Mean values are shown together with the corresponding standard error (n = 3 independent experiments). Source data are provided as a Source Data file.
