From: Deregulation of purine pathway in Bacillus subtilis and its use in riboflavin biosynthesis
Influence of various manipulations of B. subtilis rib operon on riboflavin production and genes expression. (A) Comparison of riboflavin production and yield between genetically modified rib operon mutant strains developed in this study. (B) Changes of the relative transcription levels of rib genes (ribG and ribA) between mutant strains. Results were averages from three independent experiments, and error bars represented the standard errors of the means.
