Embodiment 1

[0034] A method for cultivating microalgae, the steps are as follows:

[0035] Step 1: Use soap solution to clean the culture container and tools. After cleaning, put the culture medium and tools into an oven for drying and disinfection. The temperature in the oven is 120°C, and the disinfection time is 1.5 hours;

[0036] Step 2: preparing culture medium;

[0037] The seawater is firstly filtered with a sand filter tank, and then secondly filtered with a ceramic filter tank to filter out impurities;

[0038] After filtering, the seawater is sterilized and sterilized for the first time by heating and boiling, and then sterilized and sterilized by ultraviolet sterilizer for the second time;

[0039] Stir the sterilized seawater to increase the amount of dissolved gas in the seawater;

[0040] Add the treated seawater into the culture container, then add the nutrient solution into the culture container, and then mix the seawater and the nutrient solution evenly to obtain the c...

Abstract

The invention relates to a microalgae culture method. The microalgae culture method comprises the following steps of: step 1, cleaning a culture container and tools, and then carrying out sterilization and disinfection treatment; step 2, preparing a culture solution; step 3, inoculating algae species into the culture solution; step 4, carrying out culture management; and step 5, collecting microalgae. The microalgae culture method provided by the invention has careful microalgae culture steps, the culture container, the tools and seawater are strictly disinfected, a closed culture way is adopted, the influence of the external environment is avoided, and temperature, illumination, carbon dioxide introduction amount, pH value of the culture solution and salinity are carefully controlled, sothat culture effect is good.

Description

technical field [0001] The invention relates to the technical field of microalgae cultivation, in particular to a microalgae cultivation method. Background technique [0002] Microalgae are a type of photoautotrophic organisms that grow in water. Driven by light energy, they can absorb CO2, convert light energy into chemical substances stored in cells, and release oxygen at the same time. The cell metabolism of microalgae produces products such as polysaccharides, proteins, oils, and pigments. These metabolites have good development prospects in the fields of food, medicine, and liquid fuels. Therefore, microalgae cultivation is more and more widely used, but most of the existing microalgae cultivation methods are relatively rough, and the efficiency of microalgae cultivation is low. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a microalgae cultivation method. [0004] In order to achieve the above object,...
