Embodiment

[0046] Use UTEX2505 (Texas State University Algae Species Bank, U.S.) as the cultivated Haematococcus pluvialis algae, use the standard 3 times nitrogen BBM liquid medium as the medium, and use natural cotton with a thickness of 1 mm on both sides. A rigid PP plastic mesh of spun cloth is used as a solid support. Place 0.1-meter-wide and 1-meter-high solid carriers vertically on the ground at intervals of 20 cm, that is, place 5 solid carriers in parallel on an area 0.1 meter wide and 1 meter long. Use LED beads with wave peaks of 270nm, 390nm, 450nm, 660nm, and 840nm to form a plate-type LED array. This array is double-sided, that is, the front and back have the same LED beads, and its size is the same as the solid carrier. Place the 4 above-mentioned LED arrays between 5 solid carriers, every two solid carriers clamp a double-sided LED array and the distance between the solid carrier is 10cm. The luminous flux density ratio of the above-mentioned LED array is 1:4:10:8:1, an...

Abstract

The invention discloses a method for producing astaxanthin by using haematococcus pluvialis. The method comprises the following steps that the haematococcus pluvialis is placed in an attached cultivation system for cultivation, in the cultivation process of the haematococcus pluvialis, an artificial light source is utilized, other growth factors are manually controlled, so that the haematococcus pluvialis grows under the condition of being isolated from the outside world, and the astaxanthin accumulates. According to the method, artificial illumination is utilized for replacing sunlight, underthe condition of being completely isolated from the outside world, the haematococcus pluvialis is cultivated by the attached cultivation system to produce the astaxanthin, the influence of external factors such as weather on the growth of the haematococcus pluvialis and the growth of the astaxanthin is completely avoided, the yearly uninterrupted and stable production is achieved, and the methodis not limited to geographical locations with the high annual sunshine amount and mild climates any more and can be carried out anywhere. The method has the advantages that the output rate per unit floor area is high, and the production efficiency is far higher than that of an existing haematococcus pluvialis cultivation system.

Description

technical field [0001] The invention belongs to the technical field of biological material preparation, and specifically relates to a method for producing astaxanthin by using Haematococcus pluvialis. Background technique [0002] Natural astaxanthin is the strongest antioxidant currently known, and can be used as a new type of active factor in food, beverages, cosmetics, skin care products, and medicines. Therefore, natural astaxanthin has huge market potential. Currently recognized as the best production method of natural astaxanthin is the use of Haematococcus pluvialis. Haematococcus pluvialis is a microorganism belonging to Chlorophyta, Chlorophyceae, Volvox, Haematococceae, and Haematococcus genus. In a favorable environment, the green worm cells reproduce by dividing, while in an unfavorable environment, the worm cells stop dividing and transform into red cysts, and at the same time start to produce and accumulate a large amount of astaxanthin. According to literat...
