The biovanillin production was influenced by varying the culture pH via single control strategy conducted by separate experiments during the fermentation processes. Highest biovanillin production (124 mg/L) with 32% molar yield at culture pH 6.0 from the one-stage control method was observed. Specific growth rates (mu) of thePhanerochaete chrysosporiumand biovanillin production decreased by decreasing the culture pH from 6.0 to 3.5, which indicated that lower culture pH was not adequately apposite for biovanillin production usingPhanerochaete chrysosporiumin a 2-L stirred tank bioreactor. The development of two-stage control strategies had improved the biovanillin production (131 mg/L) and cell concentration (13.0 g/L) by about 6 and 5%, respectively. Therefore, the most influential control strategy for higher biovanillin production was discovered not to control the culture pH of the fermentation during active growth phase of thePhanerochaete chrysosporium, while the production phase should be controlled at pH 6.0.
