Abstract

The invention discloses a cultivating and producing method for haematococcus pluvialis. A haematococcus pluvialis green swarm cell is inoculated to a culture medium in a sealed tank body, a manual light-emitting diode (LED) light source is utilized for irradiation cultivating, the wavelength range of a monochromatic light emitted by the LED light source is 450nm to 640nm with the bandwidth of 30nm, two types of light sources with different wavelengths are simultaneously used according to the proportion of light intensity of red lights and blue lights, which is in a range from 2:1 to 5:1, the total light intensity is in a range from 80mu E / m2.s to 1500mu E / m2.s, the temperature during the cultivating process is maintained in a range from 15 DEG C to 28 DEG C, and the potential of hydrogen (pH) of the cultivating environment is controlled in a range from 8.0+ / -1.0 by adding carbon dioxide. The energy consumption of temperature controlling is remarkably saved, the cultivating period is shortened by above 50% compared with that of traditional methods, and the concentration of the obtained haematococcus pluvialis cell in a green algae liquid is 2 to 5 times of that of the haematococcus pluvialis cell in a green algae liquid by traditional methods.

Description

technical field

[0001] The invention relates to a method for cultivating Haematococcus pluvialis on an industrial scale. The Haematococcus pluvialis belongs to freshwater algae. Background technique

[0002] Haematococcus pluvialis, also known as Haematococcus pluvialis or Haematococcus lacustrine, belongs to Volvox, Haematococcus family.

[0003] In 1899, it was discovered that this algae is often attached to water tanks or shallow water bays near the sea in the form of a blood-red shell. The life course of this algae goes through a red dormant stage, followed by A green swimming phase followed by a red dormant phase.

[0004] In 1934, Elliot added details of the growth history of this alga from the point of view of cell morphology. Four typical cell shapes appear throughout the life cycle: small worm body, large worm body with flagella, gelatinous sheath body with no motility, and red large cells with hard cell walls-red cysts (Haematocysts). In a clean environment wit...
