Biotransformations by Plant Cell Cultures.

Abstract: Fermentation technology utilizing fungal and bacterial cultures has made enormous progress particularly in the pharmaceutical industry, but similar technology with plant cells has not reached this level of application as yet. Nevertheless, plant cell cultures represent an important potential to perform biochemical reactions on organic compounds I. Most of these reactions so far, have been confined to the biotransformation of secondary metabolites produced by plant cells2. There have been a few examples of the biotransformation of synthetically important foreign substrates3-5. Several investigations have been carried out on the biotransformation of monoterpenes'Y' and aliphatic ketones 7 by using either freely suspended or immobilised cells of-Mentha and Nicotiana species. The biotransformation of aromatic ketones to optically pure hydroxy compounds with cell cultures (free and immobilised) of carrot, tobacco and gardenia has been reported''. Thus, it is clear that plant cells provide a good source of enzymes for straightforward biotransformations and also for the synthesis of optically active molecules.
