Use of a transparent composition for photobioreactors
First Claim
1. A photobioreactor for the culture of photosensitive organisms comprising a transparent composition of at least one methacrylic polymer wherein the methacrylic polymer is a copolymer of methyl methacrylate (MMA), comprising from 90 to 99.9% by weight of MMA and from 0.1 to 10% by weight of a comonomer, said methacrylic polymer having a weight-average molecular weight ranging from 140 000 g/mol to 160 000 g/mol (PMMA standard), wherein said composition comprises at least one antifouling and/or antistatic additive.

Abstract
The present invention relates to photobioreactors and more particularly to the use of a transparent composition based on at least one methacrylic polymer for constructing installations for the culture of photosensitive organisms. This composition can be in the form of films, plates, profiled elements or cylinders such as tubes.
The invention also relates to a transparent multilayer structure comprising at least one layer of a methacrylic polymer and one layer comprising at least one antifouling additive, and to the use thereof for constructing installations for the culture of photosensitive organisms.
