Figure 1From: Optimisation of batch culture conditions for cyclodextrin glucanotransferase production from Bacillus circulans DF 9REffect of initial pH on growth and CGTase production. B. circulans was grown at various initial pHs in a medium containing 15 g/L cassava starch, 4 g/L (NH4)2SO4, 0.02 g/L MgSO4.7H2O, 0.02 g/L FeSO4, and different concentrations of KH2PO4 and K2HPO4.
