Abstract
A bioreactor for improved productivity of photosynthetic algae includes a tubular housing surrounding a tubular envelope located therein. The housing and envelope define a space therebetween to be filled with fluid. The housing and envelope are made of at least a translucent material and have inlet and outlet ports providing access to the space and the interior of the envelope. A mixer for mixing algae media is disposed inside the envelope. There is also provided a bioreactive system, wherein the envelope contains a fluid of selective refractive index and wherein, for a given geometrical relationship between the housing and the envelope, the radiation concentration power is controlled by modifying the refractive index of the fluid.
