Different stress response tests of the parental TU-6 and mutant strains. a Osmotic stress and oxidative stress tests were performed by adding different concentrations of NaCl and H₂O₂ to the MM plates, respectively. All the strains were grown at 30 °C for 3 days. b Growth of TU-6 and mutant strains on MM plates at 30 and 37 °C for 3 days, respectively
