Abstract (en)

[origin: WO8201010A1] A plant-derived cell aggregate, comprising a plurality of undifferentiated cells is disclosed, as is a plant granulate comprising a plurality of such aggregates. A process for the production of such an aggregate comprising establishing a series of cell cultures providing a range of absolute and relative amounts of cytokinin and auxin, agitating the cultures and selecting the culture(s) exhibiting the desired aggregation is also disclosed. A biosynthesis or biotransformation comprising using such a plant granulate as a catalyst is further disclosed. The present invention affords numerous advantages over conventional cell culture techniques and the use of the resulting cultures in biosynthetic systems.

Abstract (fr)

Agregat de cellules derivees des plantes comprenant une pluralite de cellules non differenciees, granule vegetal comprenant une pluralite de ces agregats. Un procede de production d'un tel agregat consiste a etablir une serie de cultures de cellules pour obtenir une gamme de quantites absolues et relatives de cytocinine et d'auxine, a agiter les cultures et a selectionner la (les) culture (s) presentant l'agregation desiree. Une biosynthese ou biotransformation consistant a utiliser un tel granule vegetal comme catalyseur est egalement decrit. L'invention presente de nombreux avantages par rapport aux techniques de cultures de cellules conventionnelles et l'utilisation des cultures resultantes dans des systemes de biosynthese.
