Description

technical field

[0001] The invention belongs to the field of research and production of microalgae, and more specifically relates to a stirring system for controlling the cycle of microalgae cultivation. Background technique

[0002] The culture conditions that affect the growth of microalgae mainly include nutritional status, temperature, light, etc., and they interact together to affect the growth rate of microalgae and the chemical composition of the product. In the process of culturing microalgae, proper agitation of the culture medium is an indispensable measure to promote the growth of microalgae. Stirring can produce intermittent light effect, obtain the effect similar to the light-dark cycle, improve the photosynthesis efficiency of microalgae; fully mix the concentration of nutrients, which is beneficial to the absorption and utilization of nutrients in the culture medium by microalgae, and can also to prevent O 2 Inhibitory effect of the accumulation of microalga...
