Methods description - Notes

Labelling experiment - After a minimum of five residence times of continuous cultivation, the feed was switched to the labelled medium. The composition of the labelling feed was based on the approach proposed by Nöh and Wiechert [1]. The feed contained for glucose, 80% [1-13 ...
