Problems solved by technology

Third, mechanical pumps commonly used in tubular photobioreactors to facilitate mixing and circulation of cell cultures in long tubes can cause severe cell damage
[0011] However, the application of plate-type reactors has encountered major engineering hurdles, namely, that it is difficult to scale up said plate-type reactors into a commercial level reactor design.
Therefore, the plate reactor is only used as a bench-top culture device and a small-scale field culture unit for studying the growth physiology of algae, and it has never been applied to the industrial cultivation of algae.

Embodiment Construction

[0057] In a first aspect, the present invention provides a photobioreactor comprising:

[0058] (a) Containers suitable for carrying fluids, which include

[0059] (i) opposing first and second side walls, wherein at least one of said first and second side walls is transparent;

[0060] (ii) opposing first and second end walls;

[0061] (iii) the bottom of the container; and

[0062] (iv) container surfaces,

[0063] wherein the first sidewall and the second sidewall comprise a plurality of separate segments, wherein the separate segments are in fluid communication;

[0064] (b) support posts for connecting the plurality of separate segments on the first side wall and the second side wall;

[0065] (c) at least one access port in fluid communication with said container;

[0066] (d) at least one outflow port in fluid communication with said container;

[0067] (e) a ventilation system in fluid communication with said container; and

[0068] (f) a temperature control sys...

Abstract

The present invention provides novel photobioreactors, modules thereof, and methods for use in culturing and harvesting algae and cyanobacteria.

Description

[0001] cross reference [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 775174, filed February 21, 2006, and U.S. Provisional Patent Application No. 60 / 799930, filed May 12, 2006 Priority to the U.S. Provisional Patent Application for , both of which are hereby incorporated by reference in their entirety. Background technique [0003] Microalgae and cyanobacteria (referred to as algae) are tiny plants that usually require simple mineral nutrients for growth and reproduction. By harnessing photon energy, such as sunlight and artificial lighting, algae photosynthetically convert water and carbon dioxide into high-value organic compounds (eg, pigments, proteins, fatty acids, carbohydrates, and secondary metabolites). Due to their exceptionally efficient light utilization and nutrient utilization, algae exhibit an order of magnitude higher growth potential than higher plants. [0004] Algae are a fairly diverse group of organisms with more ...
