Patent ID: 8476067

Claim:
A photobioreactor comprising: a) a generally vertical fluidic pathway; b) a generally vertical helically shaped fluidic pathway winding around a central core structure, the generally vertical helically shaped fluidic pathway disposed adjacent to the generally vertical fluidic pathway; c) a head cap assembly fluidly connecting a first end of the generally vertical fluidic pathway with a first end of the generally vertical helically shaped fluidic pathway; d) a base assembly fluidly connecting a second end of the generally vertical fluidic pathway with a second end of the generally vertical helically shaped fluidic pathway; such that a biologically active material is able to move fluidly, without substantial impediment, back and forth between the generally vertical fluidic pathway and the generally vertical helically shaped fluidic pathway; and e) a light source at least partially disposed within the central core structure of the generally vertical helically shaped fluidic pathway wherein the generally vertical helically shaped fluidic pathway winds about the light source.
