Key fermentation parameters with different glucose-feeding rates. The garph shows the changing patterns of total cells numbers, reducing sugar concentrations, iturin A concentrations and spores to total cells ratios in four fermentation runs with different glucose-feeding rates. Ctrl, F=0 g/L/h (a), F=0.28 g/L/h (b), F=0.56 g/L/h (c) and F=1.12 g/L/h (d). Symbols: iturin A concentration (●), reducing sugar concentration (■), number of total cells (▲), ratio of spores to total cells (△). Each point represents the mean (n = 3) ± standard deviation
