Problems solved by technology

However, this culture model algae yield is low (dry weight 5-10g m -2 d -1 ), biomass quality is also unstable, mainly due to lack of temperature control, long optical path (approximately 15-30 cm depth) and poor mixing
Direct exposure of the culture medium to the atmosphere also makes the culture system highly susceptible to air contamination
[0004] [4] The shortcomings of open waterways have promoted the development of closed photobioreactors made of transparent materials, and greatly reduced the culture depth or the ratio of culture light surface to culture capacity
[0006] [6] However, tubular photobioreactors have inherent disadvantages: cell damage or death may occur due to the hydraulic stress and shear force produced by the lipid pump

Embodiment Construction

[0011] [11] Compared with the prior art, the current invention provides a new design of photobioreactor using U-shaped frame, which has stronger configuration, flexible size, convenient construction and operation, and enables multiple A cascade of bioreactors is possible.

[0012] [12] The U-shaped frame is usually made of stainless steel (or other supporting material) to make the photobioreactor more robust; the size of the photobioreactor can have a wider range (using a U-shaped configuration makes very thin or very long reactor units possible);

[0013] [13] Such devices are easier to build by simply adding glass or other transparent materials to the sides; they also make it easier to harvest cultured algae, wash and clean the photobioreactor.

[0014] [14] The interconnectivity of each photobioreactor unit makes it possible to construct a cascade of many individual photobioreactor units, and the operating efficiency can be greatly improved.

[0015] [15] The design, fabr...

Abstract

A photobioreactor system and the methods of using the system for cultivating photosynthetic organisms, including algae, cyanobacteria, plants, and plant cells. A single photobioreactor unit consists of transparent materials (such as glass, fiberglass, or plastics) and non-transparent materials (such as stainless steel or other metals). Two or more photobioreactor units can be connected with each other in a cascade to form a photobioreactor system, which can be used for cultivation of the photosynthetic organisms.

Description

technical field [0001] [1] The present invention relates to a photobioreactor system for cultivating photosynthetic organisms and a method for using the same. Background technique [0002] [2] This application claims priority to US Provisional Application Serial No. 61,354,483 (June 14, 2010). The subject matter of this provisional application is incorporated into this application. [0003] [3] The design and optimization of photobioreactor systems are key R&D issues that determine the success of large-scale cultivation of microalgae. Microalgae culture systems can be roughly divided into two categories: open channels (or open ponds) and closed photobioreactors (Richmond, J.Appl.Phycol., 4:281-286, 1992; Chaumont, J Appl Phycol. , 5:593-604, 1993; Tredici, Handbook of microalgalculture: biotechnology and applied Phycology, pp.178-214, 2004). Open channels are circulation channels of 1000 to 5000 square meters, equipped with shallow round paddle wheels to circulate the cul...
