Hairy roots of Brugmansia candida that grew without agitation were obtained. Kinetics of growth and production of the tropane alkaloids scopolamine and hyoscyamine, with and without agitation, were studied. The exponential growth rate was higher in the roots that were exposed to shaking (0.13 d − 1 ) than in the nonagitated ones (0.09 d − 1 ). The specific production and the levels per flask of both alkaloids were enhanced without shaking. The use of these roots in large‐scale productions could be economically advantageous. It remains to be seen if the data obtained in shake flasks can be extrapolated to large‐scale bioreactors.
