Fig. 3

Growth curves of BL21(DE3) and XYF(DE3) under sabinene stress. Squares represent the growth of BL21(DE3) without sabinene stress. Circles and triangles represent the growth of BL21(DE3) and XYF(DE3) with 0.6 g/L sabinene. After 2.5 h of cultivation, sabinene was added to a final concentration of 0.6 g/L. Cell density was monitored for 24 h. The experiments were carried out in triplicates. Error bars represent the standard deviation from the mean
