Microalgae culture reactor

Abstract

The invention relates to the technical field of biology, particularly a microalgae culture reactor capable of setting different concentration CO2 culture environments, which comprises a culture box, an ultraviolet lamp tube, a gas inlet pipe and a gas outlet pipe, wherein the box body of the culture box is a transparent box body; the lower side of the front end of culture box is provided with a gas inlet; the upper side of the back end of the culture box is provided with a gas outlet; the gas inlet pipe and gas outlet pipe respectively connected with the gas inlet and gas outlet of the culture box are respectively provided with a gas flowmeter and a valve; a CO2 gas analyzer for detecting carbon dioxide concentration at the gas inlet and gas outlet is arranged outside the culture box; the gas inlet and gas outlet of the culture box are respectively provided with a gas filter unit; and a humidification system is arranged in the culture box. A plurality of culture box can be arranged in parallel. By setting different concentration CO2 culture environments to screen the wild type microalgae or corresponding mutants, the complete reactor is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a CO 2 Microalgae cultivation reactor for cultivation environment. Background technique [0002] Microalgae is a kind of low-level phytoplankton all over the world. It is widely distributed in oceans, freshwater lakes and brackish water environments. It is an important part of the primary productivity in global aquatic ecosystems. Annual CO fixation by microalgal photosynthesis 2 accounted for global CO 2 More than 40% of the fixed amount plays a pivotal role in energy conversion and carbon cycle, and the photosynthetic productivity of microalgae can reach up to 50g / m 2 / d, which is equivalent to 10-50 times the carbon sequestration capacity of forests. Theoretically speaking, cultivating 1 ton of microalgae can reduce carbon dioxide emissions by about 1.83 tons, so in all CO2 emission reductions 2 Among the technologies, carbon reduction through photosynthesis of microalgae is t...

Problems solved by technology

[0004] Currently, the use of more CO 2 Photobioreactors are mainly used for plant or animal cell culture research 2 incubator in which CO for animal cell culture 2 The incubator usually does not have a light source, but is used for plant light CO 2 It is generally difficult to ensure the sterility of the culture room in the incubator

In addition, whether it is used for plant or for animal cultivation, CO 2 Incubators, what they have in common is that they are relatively expensive, take up a lot of space, and have high operating costs. In addition, it is easy to cause bacteria, mold, etc. pollution during actual operation. Therefore, in the related research on microalgae There are fewer applications and are also limited by the above factors
