Fig. 3From: Enhancement of Surfactin yield by improving the medium composition and fermentation processTime course of foam traps during fed-batch fermentation of B. subtilis DSM 10T employing medium C. The values of bacterial enrichment (black dots), Surfactin recovery (grey rhombus) and Surfactin enrichment (white rhombus) are displayed as exemplary results of one fermentation. The addition of glucose is indicated by a dashed line after 20.83 h of cultivationBack to article page
