In vitro hairy root (HR) culture may serve as a promising solution for the extraction of tetrandrine, overcoming the limitations of natural cultivation. The present study describes the consistent production of tetrandrine from S. tetrandra hairy roots induced by different strains of Agrobacterium rhizogenes. Cultivation in woody plant medium (WPM) resulted in the highest HR biomass (0.056 g/petri-dish) and tetrandrine content (7.28 mg/L) as compared to other media. The maximum HR biomass (6.95 g dw/L) and tetrandrine production (68.69 mg/L) were obtained in the fifth week of cultivation. The presence of ammonium nitrate (800 mg/L), calcium nitrate (1156 mg/L), sucrose (20 g/L) and casein (2 g/L) enhanced the tetrandrine production. Moreover, the fed-batch cultivation demonstrated that the NH4NO3 (1200 mg/L) was an important growth limiting factor that yielded the highest tetrandrine amount (119.59 mg/L). The cultivation of hairy roots in a mist trickling bioreactor for eight weeks was less (26.24 mg/L) than in the flask. Despite a lower tetrandrine yield observed in bioreactors compared to flask cultures, refining the growth medium and fine-tuning bioreactor operations hold promise for boosting tetrandrine yield. |
