Sabinene production of BL21(DE3) and XYF(DE3). a Sabinene production using glucose as a carbon source. b Sabinene production using glycerol as a carbon source. HB4, BL21(DE3) harboring pHB7 and pTrcLower. XYFHB7, XYF(DE3) harboring pHB7 and pTrcLower. The experiments were performed in triplicates. Error bars represent the standard deviation from the mean
