A process for preparing phycoerythrin with high OD ratio from specific algae is disclosed, wherein the algae comprise: pink columnar-shaped Galaxaura oblongata, Halymenia ceylanica, Helminthocladia australis, Porphyra dentata and the combination thereof. Because there are gamogenesis, agamogenesis and vegetative propagation phases during the life cycle of some specific algae and there is no gel formed during their carpospore filament phase, the filament phase can be prolonged by controlling light intensity, temperature and nutritional condition, then phycoerythrin with high OD ratio was extracted therefrom. Also disclosed in this applicantion is the device used in the process.
L'invention porte sur un procédé de préparation de phycoérythrine à teneur élevée en oxygène dissous à partir des algues spécifiques suivantes: Galaxaura oblongata rose columnée, Halymenia ceylanica, Helminthocladia australis, Porphyra dentata et leur combinaison. En raison de la présence des phases de gamogenèse, d'agamogenèse et de propagation végétative pendant le cycle de vie de ces algues spécifiques, et du fait qu'aucun gel n'est formé pendant la phase filamentaire, cette dernière peut être prolongée en jouant sur l'intensité lumineuse, la température et les conditions nutritionnelles, et on en peut extraire de la phycoérythrine à teneur élevée en oxygène dissous. L'invention porte également sur un dispositif utilisé dans le procédé.
