Productivity of withanolides in shake-flask culture and bioreactor by elicitor and precursor treatments in cell suspension of <i>W. somnifera</i>.

For Shake-flask culture. Initial inoculum – ∼500 mg cell mass for 30 ml MS medium. For Bioreactor culture. Initial inoculum – ∼83 g FW cell mass for 5 l MS medium. Data were recorded on 28th day of culture for both the experiments. Values represent the mean ± standard error of three experiments. Mean values followed by the same letters within a column are not significantly different according to Duncan's multiple range test at 5% level.
