Manifold for bioreactor

A method for growing biological organisms, comprising:

• flowing fluid and feedstock for growth of biological organisms through a plurality of transparent conduits, wherein the conduits are coupled between a first manifold having a plurality of first openings that receive first ends of the conduits and a second manifold having a plurality of second openings that receive second ends of the conduits, the first manifold including a plurality of first passages in fluid communication with the first openings and the second manifold including a plurality of second passages in fluid communication with the second openings, and wherein the fluid and feedstock flow in series through the plurality of conduits between an inlet coupled to a first conduit in the plurality of conduits and an outlet coupled to a last conduit in the plurality of conduits;
• providing light at a wavelength between 100 nm and 700 nm to the conduits;
• and
• harvesting a mass of biological organisms produced in the conduits.

An apparatus for growing biological organisms, comprising:

• a plurality of transparent conduits;
• a light source configured to provide light at a wavelength between 100 nm and 700 nm;
• a first manifold that includes a plurality of first openings configured to receive first ends of the conduits, wherein the first manifold includes a plurality of first passages coupled to the first openings, the first passages providing fluid communication between the first ends of a pair of conduits;
• a second manifold that includes a plurality of second openings configured to receive second ends of the conduits, wherein the second manifold includes a plurality of second passages coupled to the second openings, the second passages providing fluid communication between the second ends of a pair of conduits;
• and
• a reservoir in fluid communication with the conduits, wherein the reservoir is configured to provide fluid and feedstock for growth of biological organisms to the conduits;
• wherein the first passages and the second passages are aligned such that fluid enters the apparatus through a first conduit, flows through the conduits in series, and exits the apparatus through a last conduit.
