Effect of controlled pH on OD600 (a) and enzyme activity (b). The pH value of fermentation broth of B. subtilis WB800-PHpaII-pul was adjusted constantly at pH 5.5 (black curve), pH 6.5 (orange curve), and pH 7.5 (blue curve), respectively. The averages of three independent experiments together with the corresponding standard deviations are shown for all values of OD600 and enzyme activity
