Cell suspension cultures of four plant species have been maintained under different carbon and energy supply regimes, i.e. photoautotrophy, photomixotrophy and heterotrophy, and have been assayed for their capacity to biotransform geraniol. The reactions of interconversion of geraniol into nerol, or oxidation of alcohols into their respective aldehydes, were mainly determined by the plant species, whatever the modes of culture were. A rapid metabolism of monoterpenic alcohols to unidentified compounds was observed. In one cell suspension ( Glycine max), a high biotransformation activity (40–60%) into neral and geranial was detected.
