Culture method and device of photosynthetic microorganism

Abstract

The invention relates to a culture method and device of photosynthetic microorganism. The culture method comprises the following steps: S100, connecting two ends of a photosynthetic reaction tube to an air source (200) and a vacuum pump (300) respectively; S200, starting the vacuum pump (300). Because pressure of the end, which is connected to the vacuum pump (300), of the photosynthetic reaction tube (100) is lower than that of the end, which is connected to the air source (200), of the photosynthetic reaction tube (100), the air introduced from the air source (200) flows along the photosynthetic reaction tube (100) and flows out the photosynthetic reaction tube (100) from the vacuum pump (300). The device is developed on the basis of aerodynamics principle, a vacuum pump is adopted to drive the air to flow and discharge oxygen gas; the culture liquid can flow back and forth, overall circular flow of culture liquid can be realized, the discharging of gas in tube and introducing of external gas can be finely adjusted, the energy consumption is extremely low, the structure is simple, the production and assembly can be standardized easily, and the device and method can be used to massively produce photosynthetic microorganisms.

Description

technical field [0001] The invention relates to microorganism cultivation technology, more specifically, to a method and device for cultivating photosynthetic microorganisms driven by air pressure. Background technique [0002] Among all the green organisms capable of photosynthesis on the earth, photosynthetic microorganisms, especially algae and photosynthetic bacteria, etc. have a super light energy conversion efficiency (15-18%). Moreover, simple inorganic salts can be used to produce a large amount of biomass in a short period of time under suitable temperature and moisture environment conditions. Its biological output accounts for about two-thirds of the total biomass. The light energy conversion rate of carbon 3 crops such as wheat, rice, and potato, which are people's staple food, is only 1%, and the conversion rate of carbon 4 crops such as sugarcane and corn with relatively high efficiency is only 3-5%. Therefore, these photosynthetic microorganisms become a grea...
