A process for the biomass production and a photobioreactor for cultivating phototrophic or mixotrophic organisms or cells

摘要

According to the proposed process for the production of biomass, the organisms or cells in a photobioreactor in a suspension, kept in circulation with the supply of light and of at least co₂ as a nutrient cultivated. For the cultivation, the suspension via at least one output member in an upper region of a cell culture chamber and discharged by means of at least one its downward movement in the culture vessel connection which is arranged with a horizontally extending lattice -, sieve - or net structure is delayed. At this structure, the suspension is transferred into a plurality of drops. The drops pass through a drop of a cycle, by means of which the downward movement of the suspension is decelerated and a particularly intensive exposure of the organisms contained in the nutrient solution or cells with nutrients and introduced into the reactor light is ensured.
