Problems solved by technology

[0005] In addition, microorganisms mainly use visible light with a wavelength of 400-700nm in solar radiation during the growth process, while infrared and ultraviolet rays in solar radiation outside this wavelength range cannot promote the growth of microorganisms. After long-term exposure to ultraviolet rays, it may cause damage to the photosynthetic system in microbial cells, and even lead to the death of microorganisms.

Abstract

The invention discloses a microorganism culture system, which comprises a photobioreactor, a heat absorption device and a heat storage device. Microorganisms are cultured in the photobioreactor; the heat absorption device is used for absorbing heat from the photobioreactor so as to reduce the temperature in the photobioreactor; and the heat storage device is used for storing the heat absorbed by the heat absorption device, and is used for supplying the stored heat to the photobioreactor so as to increase the temperature in the photobioreactor. Therefore, the microorganism culture system disclosed by the invention is capable of properly controlling the temperature in the photobioreactor and reasonably utilizing the energy of solar radiation.

Description

technical field [0001] The invention relates to a microorganism cultivation system, in particular to a microorganism cultivation system capable of improving the comprehensive utilization level of solar energy. Background technique [0002] A photobioreactor is a device that uses sunlight to cultivate microorganisms with photosynthetic ability. As a kind of microorganism, microalgae can effectively use light energy, convert CO 2 and inorganic salts to synthesize proteins, fats, carbohydrates and a variety of high value-added bioactive substances, which can be used to produce health food, food additives, feed, biological fertilizers, cosmetics and other natural products through microalgae cultivation. Therefore, the use of photobioreactors for high-density culture of microalgae has become more and more common. At present, there are mainly two types of photobioreactors for microalgae cultivation: open and closed. Open photobioreactors are simple to construct, low in cost, an...
