Physiological parameters of the 3H6 Fab producing strain grown at normoxic (21%), oxygen-limiting (11%) and hypoxic (8%) conditions in glucose-limited chemostat cultures at D = 0.1 h-1. Values represent the mean ± standard error from three biological replicas. YDM = yeast dry mass; glc = glucose; nd = not detected; OUR = oxygen uptake rate; CER = carbon dioxide evolution rate.
