Abstract

The invention discloses a set of apparatus and a method for culturing Haematococcus pluvialis and converting astaxanthin in large scale. The apparatus consists of a photo-bioreactor system set on the frisket, aeration equipment, culture fluid inoculation equipment and still cell harvesting equipment. Floating or sunken pulse equipment is set on the frisket. The apparatus don't need establishment of artificial culture pool and other institution, but uses natural water body to culture Haematococcus pluvialis in large scale. It is low cost, the culture temperature, illumination and water flow rate is stable, culture fluid flows with each other, aeration is continuous, culture conditions are precedent, which make the growth and increment of Haematococcus pluvialis almost at equal pace. The growth rate of Haematococcus pluvialis can reach to 25%, biomass increase is fast, doubles 3-5 days. The photo-bioreactor can be hoisted into required depth of the water, which solves the contradiction of difference of temperature, illumination and nutrition of Haematococcus pluvialis culture and astaxanthin conversion.

Description

technical field

[0001] The invention relates to a cultivation device of Haematococcus pluvialis, in particular to a device and method for large-scale cultivation of Haematococcus pluvialls and transformation of astaxanthin. Background technique

[0002] Haematococcus pluvialis is a single-celled green alga whose proliferation depends on cell division. The algae can accumulate a large amount of astaxanthin at a specific stage of growth. Astaxanthin has good coloring properties and strong antioxidant properties, and is currently mainly used in aquaculture as a feed colorant and additive for salmon and trout to improve the growth and physiological functions of salmon and trout; at the same time It is also an excellent additive for human food and health products, which can improve immunity and inhibit cancer. Therefore, the application in medicine also has great potential.

[0003] It can be seen that Haematococcus pluvialis is an economical microalgae with good development pr...
