1. 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.

Abstract
A photobioreactor (100) for use in treating polluted air and producing biomass may comprise, at least in part, a generally vertical tube or fluidic pathway (102), a generally vertical helical tube or fluidic pathway (104) having a light source (106) partially positioned within the helical fluidic pathway (104), a head cap assembly (108), and a base assembly (110). In one illustrative example, the light source (106) may be a light emitting diode (LED) or a plurality of light emitting diodes (LEDs). By one approach, a gas diffusion apparatus (112) is located at the base assembly (110) adjacent the generally vertical fluidic pathway (102).

13. A photobioreactor comprising:
-
a generally vertical fluidic pathway; a generally vertical helically shaped fluidic pathway adjacent to the generally vertical fluidic pathway; 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; 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 to permit a biologically active material to move fluidly, without substantial impediment, back and forth between the generally vertical fluidic pathway and the generally vertical helically shaped fluidic pathway; and a gas diffusion apparatus located at the second end of the generally vertical fluidic pathway, wherein the gas diffusion apparatus comprises a sparger configured to inject gas bubbles at the base assembly and wherein the injected gas bubbles create a fluid movement within the photobioreactor that moves upward through the generally vertical fluidic pathway and downward through the generally vertical helically shaped fluidic pathway. - View Dependent Claims (14)
