PHOTOREACTOR WITH EXTERNAL LIGHT SOURCE

摘要

PURPOSE: A photoreator with an external light source is provided to actively supply light and gas to microalgae and to culture microalgae using the light and the gas. CONSTITUTION: A photoreactor with an external light comprises: a flow path (14) with a tubular vertical section; a culture machine (12) which is connected to one or more flow paths; and a light emitting element (15) which is mounted at the outside of the culture machine and irradiates the flow paths by light. The culture machine and the flow paths are made of a light transmitting material. In the culture machine, one or more flow paths are piled and inclined. Each end of the flow paths is connected to another one.
