Optimization of octanoic acid and sulfur donor concentrations for lipoic acid production by Pseudomonas reptilivora
Using the optimal concentrations of octanoic acid (0.75 mM) and ethyl mercaptan (2 mM), as the most effective sulfur donor, Pseudomonas reptilivora produced 74 mu g lipoic acid per dry cell weight at pH 7.5 and 30 degrees C in a fermenter over 9 h. The dry cell weight was 13.9 g l(-1).
