There is a research gap about applying titania–graphene oxide (GO-TiO2) nanocomposite and coronatine as elicitors in the cell suspension culture of T. baccata.
The effects of two elicitors of GO-TiO2 (30 µg/L) and coronatine (10 µM) were examined to improve the production of five different taxanes in the cell suspension culture of T. baccata.
The suspension culture was prepared from the callus of T. baccata stems explant. Next, both elicitors of coronatine (10 µM) and GO-TiO2 (30 µg/L) were applied, sampling occurred 2, 4, 16 days after elicitation, and all five taxanes were quantified using HPLC.
The amounts of 10-DAB III ranged from 0.84 mg/L (for control) to 9.17 mg/L (day 16 after elicitation with GO-TiO2). The production of BAC III ranged from zero (for control) to 7.69 mg/L (day 4 with GO-TiO2). The maximum production of 10-deacetyltaxol was observed in control on day 16 with the amount of 1.85 mg/L, followed by a lower level of 0.825 mg/L on day 2 with coronatine treatment. Considering cephalomannine, only elicitation of GO-TiO2 over all three different sampling times (i.e., days 2, 4, and 16) resulted in sensible quantities. The maximum magnitudes of taxol were acquired when GO-TiO2 was applied on day 4 and day 16 (1.345 mg/L and 0.965 mg/L, respectively).
The results indicated the potential positive effects of both elicitors, particularly GO-TiO2 nanocomposite, to improve taxanes production.
