The invention relates to a bioreactor for cultivating phototrophic organisms in an aqueous culture medium. The reactor parts and/or fittings that come into contact with the culture medium are entirely or partially coated with a silicone layer, and the surface of the silicone layer has a contact angle to the water of at least 100&#xb0;.

Bioreactor comprising a silicone coating

The invention relates to a bioreactor for cultivating phototrophic organisms in an aqueous culture medium, the reactor parts that come into contact with the culture medium being entirely or partially produced from silicone materials. The invention is characterized in that the silicone materials are produced from addition-crosslinked silicones, and the surface of the silicone materials has a contact angle to the water of at least 100&#xb0;.

Bioreactor consisting of silicone materials

The invention relates to a tubular photobioreactor that has a core structure in the shape of a truncated cone and one or more transparent or translucent tubes which are helically wound around the outer surface and/or inner surface of the core structure. The tubular photobioreactor is characterized in that the transparent or translucent tube has at least two chambers, through at least one of which the cultivation medium flows and through at least one of which a heat transfer medium flows.
