additional information
production of beta-caryophyllene by assembling a biosynthetic pathway in an engineered Escherichia coli strain of which phosphoglucose isomerase gene has been deleted. The 1-deoxy-D-xylulose 5-phosphate (DXP) or heterologous mevalonate (MVA) pathways are employed. Geranyl diphosphate synthase (GPPS2 gene from Abies grandis), glucose-6-phosphate dehydrogenase (G6PDH gene), and beta-caryophyllene synthase genes are co-overexpressed in the engineered strain. The final genetically modified strain, YJM59, produces 220 mg/l of beta-caryophyllene in flask culture. Evaluation of fed-batch fermentation for the production of beta-caryophyllene. After induction for 60 h, the YJM59 strain produces beta-caryophyllene at a concentration of 1520 mg/l. The volumetric production fermented in the aerobic fed-batch is 0.34 mg/(l/h/OD600) and the conversion efficiency of glucose to beta-caryophyllene (gram to gram) is 1.69%. Method evaluation with beta-caryophyllene synthases from different origins, QHS1 from Artemisia annua is the most effective of the three enzymes, compared to TPS21 from Arabidopsis thaliana and TPS23 from Zea perennis.

additional information
in a robustly acetate-utilizing Escherichia coli strain, acetyl-CoA synthase (ACS), Artemisia annua beta-caryophyllene synthase (QHS1) and geranyl diphosphate synthase (GPPS2) are co-expressed to establish the engineered strain converting acetic acid to beta-caryophyllene. To further enhance beta-caryophyllene production from acetic acid, the heterologous mevalonate pathway is introduced into the cells. Acetoacetyl-CoA synthase (AACS) is also expressed in the cells to increase the precursor acetoacetyl-CoA and accordingly resulted in the increase of beta-caryophyllene. The final genetically modified strain, YJM67, accumulates the production of biomass and beta-caryophyllene up to 12.6 and 1.05 g/l during 72 h, respectively, with a specific productivity of 1.15 mg/h/g dry cells, and the conversion efficiency of acetic acid to beta-caryophyllene (gram to gram) reaching 2.1%. The yield of beta-caryophyllene on acetic acid of this strain also reaches about 5.6 % of the theoretical yield.

gene OkBCS silencing in Ocimum kilimandscharicum plants via Agrobacterium tumefaciens strain GV3101 mediated transfection. beta-Caryophyllene and alpha-humulene levels decrease by about 20% in silenced plants compared to controls. The silencing effect is more prominent in systemic leaves with 95% reduction in OkBCS transcripts against 51% decrease in local leaves
