Cell death in three TLFB processes (filled symbols) and in two MLFB processes at 30°C (open symbols). Solid line designated M represents the methanol concentration in culture broth in one of the TLFB processes. In the MLFB process, the methanol concentration is close to zero (not visible in the figure).
