Overexpression of otcR improves OTC production. A. OTC production of S. rimosus M4018 and M4018::otcR in R5 and FM media. The values are means ± SD from three independent experiments. B. Activities of oxy promoters in S. rimosus M4018 and M4018::otcR reported by GFP. Green fluorescence of different strains was measured after incubation in R5 medium at stationary phase (10 d). The values are means ± SD from three independent experiments.
