The β-carotene content and HMG-CoA content of the control strain Y.L-1, Y.L-3 overexpressing one copy of erg13, Y.L-4 overexpressing two copies of erg13, Y.L-5 overexpressing three copies of erg13, and Y.L-6 overexpressing Hxk and two copies of erg13 in YPD medium after 96 h of shake-flask fermentation. (A) The β-carotene content of Y.L-1, Y.L-3, Y.L-4, Y.L-5, and Y.L-6. (B) The HMG-CoA content of Y.L-1, Y.L-3, Y.L-4, Y.L-5, and Y.L-6. Error bars represent standard deviations (n = 3). The asterisks indicate a significant difference compared with the control (**p < 0.01).
