Fermentation results and transcriptional analysis of the TyrR mutant strains. a Fermentation results of the TyrR mutant strains in shake flasks. Black columns stands for OD600 and gray columns stands for the L-Phe production. b Real-time PCR analysis consequences of the genes regulated by the TyrR protein in Xllp08 contrast to Xllp04. Experiments were conducted in triplicate
