Fig. 7From: Enhancement of ascomycin production via a combination of atmospheric and room temperature plasma mutagenesis in Streptomyces hygroscopicus and medium optimizationScale-up fermentation of S. hygroscopicus SFK-36 under optimized fermentation conditions in a 5 L fermenter. The pH-controlling strategies were conducted with no controlling (a), or maintained at a constant pH of 6.0 (b), 6.5 (c), 7.0 (d), respectivelyBack to article page
