Fig. 1From: Efficient de novo production of bioactive cordycepin by Aspergillus oryzae using a food-grade expression platformCordycepin (COR) and 3′-deoxyinosine (3′-dl) analysis in culture broth of the engineered A. oryzae strain (AoCordy-T1). The chromatogram peak and UV absorption spectra (right box) of purine nucleosides analyzed by HPLC-UV are shown (A). The mass spectra patterns of recombinant cordycepin and its deaminated product (3′-dl) produced by the engineered strain were verified by LC-MS compared with authentic standards (STD) (B)Back to article page
