Growth of Leonurus sibiricus L. roots with over-expression of AtPAP1 transcriptional factor in closed bioreactor, production of bioactive phenolic compounds and evaluation of their biological activity
چکیده انگلیسی
Fast-growing transgenic root cultures of Leonurus sibiricus with the AtPAP1 transcriptional factor may be used as a base for potential large-scale phenolic acids production. The present study investigates the effect of different volumes of medium (300 mL, 1 L, 3 L, 5 L flasks) and a 5 L bioreactor on biomass increase and phenolic acids production by transgenic roots of L. sibiricus. Of these cultures, those from the 5 L bioreactor demonstrated the greatest increase in dry weight (20.83 g/L) and highest yields of phenolic acids (chlorogenic acid 448 mg/L and caffeic acid 302 mg/L). Additionally, they also displayed a cytotoxic effect on melanoma cells across the range of tested concentrations, as well as antioxidant activity on human blood plasma. This approach may serve as an alternative to conventional field crops for enabling large-scale production of the active constituents of AtPAP1 root extract, which would be of great value for pharmaceutical production.
