Fig. 2From: A bacterial negative transcription regulator binding on an inverted repeat in the promoter for epothilone biosynthesisThe growth curves (a) and production abilities of epothilones (b) in M. xanthus ZE9 and its mutants. The growth curves were assayed in CYE medium. The production of epothilones were detected in the CYE medium supplemented with methyl oleate (CMO medium). The error bars represent the standard deviation of three independent experiments. **P < 0.01 and *P < 0.05, respectivelyBack to article page
