Tolerance of E. coli BL21(DE3) cells to styrene toxicity and ISPR with different solvents. a Growth response of E. coli BL21(DE3) cells to 0, 100, 200, 300, and 400 mg/L styrene in LB medium. b Effect of different solvents on styrene production and cell growth. c Time course of biomass by E. coli BL0801 cells in biphasic and single-phase cultures. Error bars represent one standard deviation from triplicate experiments
