- Values represent the averages based on four independent experiments and the error value represents one standard deviation. To retain the plasmids, 25 μg mL−1 chloramphenicol was added. Cultivation was terminated at 15–17 h after inoculation when >95% of the total sugar (>38 g L−1) had been consumed
