Embodiment 1

[0066]Example 1 The influence of temperature and light intensity on the growth of spirulina

[0067]First prepare the following medium: 25.2g L-1NaHCO3, 2.5g L-1NaNO3, 0.04g L-1CaCl2·2H2O,1.0g L-1K2SO4,0.5g L-1K2HPO4,0.2g L-1MgSO4·7H2O,0.01g L-1FeSO4·7H2O,1.979g L-1MoCl2·4H2O, 3.092g L-1H3BO3, 0.484g L-1NaMo4·2H2O, 0.23g L-1ZnSO4·7H2O, 0.183g L-1NaVO3, 0.048g L-1CoCl2·6H2O, 0.2g L-1CuSO4·5H2O.

[0068]The medium was injected into a rectangular tube photobioreactor with a height of 10 cm, a width of 5.0 cm, and a length of 20 cm. The mixing of the reaction was provided by a rocker-type shaker with a rotating speed of 60 rpm and a continuous working mode. Then insert fresh Spirulina FACHB-314 into the reactor, and control the final inoculation volume and inoculation density to 200ml and 0.1g L respectively-1. Finally, at 50, 200 and 400μmol·m-2·S-1Under three continuous light intensities, to investigate the influence of temperature of 15, 20, 25, 30, 35, 40 ℃ on the growth of spirulina, the...

Embodiment 2

[0070]Example 2 Cultivation of Spirulina in Smart Open Pool

[0071]Inject 400L of the medium described in Example 1 into the cultivation area of ​​2.0m2In the racetrack pool, the thickness of the liquid layer after the medium is injected is 20.0cm. The mixing of the culture solution in the open pond is driven by its stirring paddle, which is connected to the controller of the intelligent mixing system through a data line and operates under instructions from the controller. In addition, the controller is also connected to a light intensity meter and a thermometer, respectively, for the detection and acquisition of light intensity and temperature, where the measured temperature is the temperature of the culture solution. The controller will control the rotation speed of the stirring paddle based on the real-time detected data and through a pre-programmed program. The control is based on the experimental results derived from Example 1. The specific intelligent open pool mixing control st...

Abstract

The invention discloses a method for culturing microalgae based on an artificial intelligence microalgae mixing system, and relates to the technical field of microalgae culture. According to the method, mixing intensity is adjusted by measuring the temperature and the light intensity in real time to realize balanced management of the mixing energy. More importantly, the method can enhance the mixing efficiency of the saved energy in the optimal growth time, so that the production efficiency of the microalgae is expected to be further improved. Therefore, the method provided by the invention can ensure the efficient growth of microalgae while reducing mixing energy consumption, and has great potential for application.

Description

Technical field[0001]The invention relates to the technical field of microalgae cultivation, in particular to an artificial intelligence-based microalgae cultivation method.Background technique[0002]As a type of photosynthetic microorganisms, microalgae have fast reproduction speed, high photosynthesis efficiency, CO2It has the advantages of high fixation efficiency, rich in protein, polysaccharides, polyunsaturated fatty acids, pigments and other nutrients, and its cultivation is easy and does not occupy valuable farmland resources. Due to the above-mentioned advantages, microalgae have huge application potential in food, aquatic animal feed, bioenergy, sewage treatment, carbon emission reduction, etc., and they are the most favorable candidates to solve the current environmental, energy and food crises.[0003]An efficient and low-cost cultivation system is the key to promoting the large-scale industrial application of microalgae. At present, the culture systems of microalgae mainly...
