Growth tests and PI uptake analyses of MU-11 and selected mutants in EFB media. a Growth of MU-11 and selected mutants. Cells were serially transferred at a ratio of 1% in EFB media with lysine concentrations from low to high. b PI uptake of MU-11 and selected mutant cells from the 40 h-samples cultivated in EFB media containing 100 g/L lysine. The growth curves of the control groups were linked to highlight the growth differences between controls and mutants. Data are the mean and standard deviation of independent triplicates
