The effects of six microelements (Cu2+, Mn2+, Fe2+, Mo2+, Zn2+, Co2+) on the production of betalains and the growth of suspension cultures of Beta vulgaris were studied. The increase of Co2+ from 1–5 μM resulted in a 60% increment on the production of betalains. A positive effect of this divalent ion was only accomplished when it was added at the beginning of the culture. This was related to a doubling in the specific betalains production rate compared to B5 control medium. No effects on cell growth and ratio of betacyanines to betaxanthines were observed. Mo2+, Fe2+ and Cu2+ presented a positive but less marked effect, while the increase of Mn2+ did not show effects on the production of betalains compared to B5 control medium.
