Analysis and identification of the product by GC–MS. A Total ion current chromatogram of the E. coli carrying pET-28a( +). B Total ion current chromatogram of the β-caryophyllene standard (the peak of β-caryophyllene was marked with an arrow corresponding to the retain time 14.6 min). C Total ion current chromatogram of the E. coli carrying pET-tsp7. D Mass spectra of the β-caryophyllene standard. E Mass spectra of the fermentation product
