Figure 2From: Production of surfactin from Bacillus subtilis MZ-7 grown on pharmamedia commercial mediumTime course of growth of B. subtilis MZ-7 on two growth media. Each point is the result of 3 measurements. The error bars show the standard deviation of the measurements. The following parameters were monitored: pH of the growth medium (â–²), CFU (â– ), and ability of samples to inhibit the growth of B. fusiformis (â—‹).Back to article page
