Time course of CDW and Surfactin concentrations of B. subtilis DSM 10T during shake flask cultivations in medium B and further optimized medium C. The achieved CDW [g/L] is shown in a, whereas resulting Surfactin concentrations [g/L] are illustrated in b. The results of cultivation in medium B are given as black dots. Data from cultivations in medium C are presented as white dots. The cultivations were conducted as duplicates and in time-displaced flasks to illustrate a continuous course of growth and Surfactin production
