Photo bioreactor for algae culture

Abstract

The invention discloses a photo bioreactor for algae culture, and is used for technical field of bioengineering. Each of culture unit includes light culture grooves and a buffer tank connected with the light culture grooves; all the buffer tanks are arranged in sequence and every two adjacent buffer tanks communicate with each other to form a closed circulating system to avoid that a culture solution is contaminated by outside microorganisms; moreover, all the culture units are independent from each other, so that classified culture of algae is realized; moreover, different light culture grooves can receive different light intensity, and thereby, growth characteristics of the algae at different stages can be fully adapted; and meanwhile, a thermostat, an air supply mechanism and all the culture units are independent from each other, so that management is more convenient, and large-scale culture is realized more conveniently.

Description

Technical field [0001] The invention relates to the technical field of bioengineering, in particular to a photobioreactor for cultivating algae. Background technique [0002] The existing photobioreactors used for algae cultivation are generally in the form of open track ponds or closed glass pipes. However, the use of open track ponds to cultivate algae is not only difficult to adjust the growth temperature, light and other culture conditions of the algae, but also It is easy to be contaminated and the product is unstable. Moreover, when the algae is cultured in the laboratory, artificial light sources are used, the production scale is small, and the production cost is high, which is not suitable for large-scale production of algae products. For the photobioreactor using closed glass pipes to cultivate algae, although the pollution problem is solved, the reactor cannot adjust the light intensity and temperature, the growth of the algae is greatly affected, and the production cyc...

Problems solved by technology

[0002] Existing photobioreactors for algae cultivation are generally in the form of open track pools or closed glass pipes. However, it is difficult to adjust the growth temperature, light and other cultivation conditions of algae when using open track pools to cultivate algae. It is easy to be polluted and the product is unstable. Moreover, when algae are cultivated in the laboratory, artificial light sources are used, the production scale is small, and the production cost is high. It is not suitable for large-scale production of algae products.

For the cultivation of algae in a photobioreactor with closed glass tubes, although the pollution problem is solved, the reactor cannot adjust the light intensity and temperature, which greatly affects the growth of algae and prolongs the production cycle.
