Abstract

L'invention concerne un procédé de faire croître une biomasse phototrope dans une zone de réaction comprenant un mélange réactif qui déclenche une photosynthèse à la suite d'une exposition à un rayonnement lumineux actif au plan photosynthétique. Le mélange comprend une biomasse phototrope pouvant augmenter au sein de la zone de réaction. Cette invention porte sur plusieurs aspects : l'alimentation en dioxyde de carbone est modulée en réponse aux paramètres de transformation détectés ; les apports à la zone de réaction sont modulés sur la base de changements survenant dans la fourniture de dioxyde de carbone ; une dilution de l'alimentation en dioxyde de carbone est effectuée ; la pression de l'alimentation en dioxyde de carbone est augmentée ; de l'eau est condensée à partir de l'alimentation contenant du dioxyde de carbone et récupérée pour réutilisation ; la biomasse produite est recueillie à un taux proche équivalant peu ou prou à un taux de croissance prédéterminé de la masse de la biomasse phototrophe.
