HPLC analysis of carotenoids in α-carotene and β-carotene-accumulating E. coli BL21 (DE3) cells co-transformed with pCDF-2 Ek/LIC-CitCYP97C and pRSF-2 Ek/LIC-CitHYb (b), pCDF-2 Ek/LIC-CitCYP97C and pRSF-2 Ek/LIC-CitCYP97A (c), pCDF-2 Ek/LIC-CitCYP97C and pRSF-2 Ek/LIC-CitCYP97B (d). Carotenoids extracted from the suspension cultures of α-carotene and β-carotene-accumulating E. coli BL21 (DE3) cells with pRSF-2 (empty vector) were used as control (a). β-Car, β-carotene; β-Cry, β-cryptoxanthin; Zea, zeaxanthin; Zein, zeinoxanthin; Lut, lutein
