Embodiment 1

[0036] The leftovers processed by kelp are used as the raw material of the microalgae culture solution, and its preparation method is as follows:

[0037] 1. Select the leftovers of kelp processing, rinse them with clean water and set aside;

[0038] 2. Put the kelp into the extract, and then use a pulverizer to physically crush it to make it

[0039] Nutrients are fully analyzed;

[0040] 3. Homogenize the kelp obtained by crushing, filter and degum to obtain clear liquid;

[0041] 4. Concentrate the supernatant according to the required concentration;

[0042] 5. The concentrated solution is subjected to high temperature and high pressure treatment to obtain the microalgae culture solution.

[0043] The content of each main component in the microalgae culture medium obtained in the experiment is compared with the content of each main component in the seawater microalgae culture medium commonly used in the world below:

[0044] Table 1. Comparison of the contents of eac...

Abstract

The present invention relates to culture medium for micro algae, especially micro algae culturing liquid and its preparation process. The micro algae culturing liquid contains extracted liquid of large algae. The preparation process includes selecting and washing large algae; crushing large algae in some soaking liquid; filtering algae powder or algase slurry to obtain clear liquid without glue; concentrating and processing the concentrate at high temperature and high pressure to obtain the culture liquid. Compared with available technology, the present invention has the advantages of rich components for promoting the growth of micro algae and raising the nutritive value and physiological function of micro algae, no chemical reagent contained and no environmental pollution.

Description

technical field [0001] The invention relates to a culture medium for microorganisms, in particular to a microalgae culture solution and a preparation method thereof. Background technique [0002] Existing microalgae culture fluids are all chemical culture fluids, that is, culture fluids made by dissolving and mixing chemical reagents containing various nutrients. When applied to commercial production, this chemical culture solution has the following disadvantages: (1) The composition is complex, and some solutions need to be prepared immediately, which is time-consuming and laborious, and the operation process is cumbersome. (2) When used to cultivate food-grade microalgae products, some of the main components (such as fertilizer nitrogen and fertilizer phosphorus) do not meet the food production specifications, and the elution process in the product processing process is increased. At the same time, the discharge of this type of culture fluid will also cause a certain degr...
