PROCEDES DE FIXATION/COMPLEMENTATION DE MOLECULES BIOLOGIQUEMENT ACTIVES PAR DES CYANOBACTERIES ET DES MICRO-ALGUES OU DES FRACTIONS DE CYANOBACTERIES ET DE MICRO-ALGUES

Enriching (M1) intact photosynthetic microorganisms (A) in biologically active molecules (I) by growing them in optimized medium under the best suited physicochemical conditions, then harvesting and incubation in a specific induction medium that contains (I). Enriching intact photosynthetic microorganisms (A) in biologically active molecules (I) by growing them in optimized medium under the best suited physicochemical conditions, then harvesting and incubating them in a specific induction medium that contains (I) for 1-12 hours. (I) either binds to the cell wall or is integrated into cell components, the cells are recovered by filtration and dried (freeze-dried, spray dried or using some other method) so that only the amount of (I) that has become bound is used. Independent claims are also included for the following: (1) a method similar to (M1) in which harvested cells are resuspended in physiological buffer, milled and the resulting lysate incubated, in the cold and in absence of light, with a known quantity of (I) for 1-8 hours, then freeze- or spray-dried so that the whole of (I) used is present in the final product; and (2) products of the new methods.
