| 520 | 3 | _aPlant cell suspension cultures of Thevetia peruviana has been explored for pharmaceutical compounds production. The aim of this study was to evaluate the agitation rate effect on growth and metabolism behavior of T. peruviana cells grown in a 7 L stirred tank reactor. Increases in agitation rates favored cell growth, secondary metabolites production and metabolic activity. The highest biomass concentration 11.92?±?0.25 g DW/L was reached at 550 rpm. The oxidase-reductase activity was stimulated at 550 and 800 rpm. Guaiacol peroxidase activity showed an increase for 300 and 550 rpm after day 7. High levels of extracellular Reactive Oxygen Species (ROS)were observed at day 7 for 550 and 800 rpm. Intracellular phenolic compounds (PC)showed an upward trend until day 7 with a maximum phenolic production of 57.78?±?4.70 mg EGA/100 g FW for 550 rpm. These results indicated that cells responded to ROS stress in a non-enzymatic manner during the first 7 days of culture, increasing PC production with antioxidant capacity. After 7 days, cells responded enzymatically. Intracellullar cardiac glycoside showed a relative increase of 1.7 and 2.1 times for 550 and 800 rpm, respectively. The maximum extracellular production of cardiac glycoside for 550 and 800 rpm was 770.34?±?42.84 mg EP/L. Taken together this study established reactor culture conditions for production of cardiac glycosides and PC, especially taxifolin. | |
