A kind of cultivation method and cultivation device of Haematococcus pluvialis

Abstract

The invention specifically relates to a culture method and culture apparatus for Haematococcus pluvialis, belonging to the field of industrial application of microalgae. Specifically, the invention discloses a laminated thin-plate culture apparatus for Haematococcus pluvialis. The laminated thin-plate culture apparatus is characterized by comprising a plurality of thin plates laminated along a vertical direction, wherein the plurality of thin plates are supported so as to allow a predetermined distance to be left between every two adjacent thin plates; each thin plate extends along a horizontal direction and has opposite upper and lower surfaces; the periphery of each thin plate is provided with a cofferdam part upwardly extending from the upper surface of the thin plate; the upper surface of the each thin plate and the interior surface of the corresponding cofferdam part form space used for accommodating a nutrient solution for Haematococcus pluvialis; and the cofferdam part of the each thin plate is 1.5 mm to 4.5 mm higher than the corresponding upper surface of the thin plate.

Description

[0001] field of invention [0002] The present application relates to the field of industrial application of microalgae, in particular to a cultivation method and cultivation device for Haematococcus pluvialis. [0003] Background of the invention [0004] Astaxanthin has been proven to improve the body's immunity, prevent ultraviolet (UV-A) damage to cells, inhibit the growth of cancer cells, delay the aging process, and prevent cardiovascular diseases, so it has great medical application prospects (Han D, Li Y, Hu Q. Astaxanthin in microalgae: pathways, functions and biotechnological implications. Algae, 2013, 28:131-147). In addition, astaxanthin is also the main component of the pigment of salmon (Salmon). For artificially farmed salmon, etc., it is necessary to add astaxanthin to the feed to ensure the bright red color of the fish. With the rapid development of this kind of economic aquatic animal breeding industry, the market demand for astaxanthin is also increasing ra...

AI Technical Summary

Problems solved by technology

However, these culture methods and culture devices have the disadvantages of large energy consumption, low cell density (the yield of cell dry weight is less than 1g / L), fast propagation speed inside the pollution source, low light utilization efficiency, large space occupation, large water consumption, and limited space per unit volume. Disadvantages such as low yield

Currently there is no mold treatment that does not leave a toxic residue on the algae

In addition, the semi-dry culture method needs to continuously or intermittently pump the culture fluid to the top of the water-absorbing material and spray it down, which also requires a lot of energy consumption
