Photobioreactor

A photobioreactor for cultivation of microalgae or cyanobacteria comprising a support structure comprising a plurality of posts, a plurality of cross bars and a plurality of supporting angles wherein said plurality of cross bars and said plurality of supporting angles installed on said posts constructed and arranged to provide a bank of frames fastened with wire nettings;

• said bank of frames further comprising an inflatable transparent or translucent film polymeric sleeve sandwiched between a bank of abutted in-line line frames with wire nettings disposed on an underside of said polymeric sleeve;
• wherein each frame of said bank of frames includes two longitudinal Z-profiles and two transverse strips and wherein said bank of frames includes transparent or translucent glass panes in connection with lateral sections of said frame;
• wherein said inflatable polymeric sleeve an includes inlet port and an outlet port and when said polymeric sleeve when inflated forms a small duct and is inclined at an angle determined by the incline of the abutted frames;
• wherein said Z-profiled frame section supports said transparent or translucent glass panes and include fastening members to secure said glass panes;
• and
• wherein said support structure include two parallel row rows of posts and two parallel rows of inclined supporting angles secured to said posts;
• and wherein said inflated polymeric sleeve duct is in operative connection with a first and a second external header including said inlet port and said outlet port for supplying and removing culturing media, aqueous suspension and/or gases into an out of the photobioreactor for culturing microalgae or cyanobacteria.
