Embodiment 1

[0050] Embodiment 1 utilizes seaweed extract and bacterial liquid to promote the method of Haematococcus pluvialis biomass and astaxanthin production

[0051] Embodiments of the present invention include the following steps:

[0052] 1. Cell culture of Haematococcus pluvialis

[0053] (1) Preparation of Gracilaria seaweed extract:

[0054] Gracilaria tenuistipitata and Gracilaria edulis used in this example are Gracilaria tenuistipitata. Take fresh algae of the genus Gracilaria, mix and grind them with tap water at a ratio of 1:20, filter through gauze, and obtain a liquid that is boiled and cooled to obtain the extract of Gracilaria.

[0055] (2) Preparation of Haematococcus pluvialis culture medium:

[0056] Add Gracilaria extract in basal medium (addition concentration is Gracilaria extract: Haematococcus pluvialis basal culture solution=1:500), the composition of basal medium is as in Table 1:

[0057] Table 1 BG11 liquid medium formula

Abstract

The invention relates to the technical field of biological culture for producing high-added-value products from microalgae, in particular to a haematococcus pluvialis culture medium, a preparation method thereof and a haematococcus pluvialis culture method. The haematococcus pluvialis culture medium comprises a basic culture medium, a gracilaria seaweed extract and lysine bacillus. According to the method, the gracilaria seaweed extract and the lysine bacillus are added in the haematococcus pluvialis culture process, so that the biomass of the haematococcus pluvialis and the yield of astaxanthin can be remarkably increased.

Description

technical field [0001] The invention relates to the technical field of biological cultivation of high value-added products produced by microalgae, in particular to a medium for Haematococcus pluvialis, a preparation method thereof, and a cultivation method for Haematococcus pluvialls. Background technique [0002] Natural astaxanthin is a carotenoid pigment with high antioxidant activity. Its antioxidant effect is 10 times that of β-carotene and 550 times that of vitamin E. Astaxanthin can scavenge reactive oxygen species and free radicals, enhance the immunity of organisms, assist the recovery of cardiovascular diseases, immune system, inflammation and neurodegenerative diseases, and have the functions of anti-aging and repairing ultraviolet damage. It is used in food It has broad application prospects in medicine and medicine; it can also be directly stored in animal tissues through animal consumption, making the meat and shell of salmon, trout, shrimp, etc. appear bright ...
