Abstract

Bioreactors for adventitious root culture have been developed to obtain biomass and plant bioactive compounds in large quantities. These technologies provide a great opportunity to produce biomass and bioactive compounds more quickly from Gynura procumbens compared to conventional plant cultivation systems. In previous studies, biomass and bioactive compounds of G. procumbens adventitious roots were successfully increased using a small‐scale bioreactor. In this study, a pilot bioreactor the capacity of 19 L polycarbonate gallon was successfully developed. This bioreactor can be sterilized under the pressure of 0.18 MPa for approximately 60 min. While the bioreactor could not be sterilized when the pressure was less than 0.18 MPa damage may have occurred to the bioreactor vessel at pressures exceeding 0.18 MPa. The results of the chemical grade test as root culture media showed that MS‐Tek provided an optimal root biomass compared to MS‐PA after a 35‐day of the culture period. In addition, the productivity of the total phenolics and flavonoids of adventitious root in MS‐PA was higher than in MS‐Tek. This novel pilot bioreactor is suitable for G. procumbens adventitious root culture, and the technical‐grade chemicals are suitable for improving root biomass production.

Abstract

The valuable extract of bioactive compounds from Gynura procumbens has been widely manufactured into various health products. The demand for these compounds is continuously increasing, but production through conventional farming methods is insufficient due to limited agricultural land and environmental stresses. An alternative to producing plant biomass is in vitro cultivation methods. This method requires less space and enables biomass propagation in a controlled condition that can facilitate stable and efficient production of plant secondary metabolites. This study evaluated the effect of inoculum subculture periods and culture methods on G. procumbens biomass and secondary metabolite production in a bioreactor. The 3-L airlift balloon type-bubble bioreactors was modified in this study to adopt the treatment of 1st-5th subculture periods and fed- and batch-cultivation strategies. We found the G. procumbens adventitious root culture was optimally derived from the 1st subculture produced biomass of 148.02±1.45 g FW and 8.59±0.12 g DW, and TPC (14.48±1.08 mg GAE/g DW) and TFC (116.89±0.44 mg KE/g DW and 33.97±0.13 mg QE/g DW). Additionally, the fed method after 28 days of culture using double distilled water replenishment improved adventitious root biomass (213.75±35.00 g FW and 11.21±0.18 g DW), while nutrient replenishment improved TFC (52.14±0.44 mg KE/g DW and 14.54±0.13 mg QE/g DW). These results can be used to optimize the cultivation of G. procumbens adventitious roots in a large-scale bioreactor.
