Problems solved by technology

[0003] Spirulina, as a plant with comprehensive nutritional components, especially rich in amino acids, has been recognized for its role. However, due to the low unit yield and slow growth rate of spirulina culture, the growth cost is too high, and it has not been popular for a long time. The food that is willing to accept, how to reduce its growth cost, improve its unit yield, accelerate its growth rate, is the problem to be solved in the present invention
In this regard, there is no relevant literature report

Embodiment 1

[0012] Each liter of culture medium contains:

[0013] Baking soda 10g

[0014] salt 2g

[0015] water 1000mL

[0016] L-Arginine: 0.25g at the algae domestication stage; 0.3g at the breeding stage of small ponds; 0.5g at the breeding stage of medium and large ponds.

[0017] Application method:

[0018] (1) Selection of algae species, domestication of algae species, and breeding of small ponds.

[0019] Selected and optimized blunt-topped or grown-up spirulina species are inoculated into glass bottles for cultivation. When the OD value of the algae concentration reaches 0.5-0.8, expand to 5-12 liters of glass bottle for cultivation. At this time, start in the culture medium Add L-arginine to acclimate algae. The glass bottle culture is mainly indoors. After the pure algae are cultivated in the laboratory, they are inoculated into the outer small pond for expansion. When the OD value of the algae concentration reaches 0.3-0.6, L-arginine can be added for cultivation, whic...

[0023] Each liter of culture medium contains

[0024] Baking soda 10g

[0025] salt 2g

[0026] Sodium nitrate 2g

[0027] water 1000mL

[0028] L-Arginine: 0.2g at the algae domestication stage; 0.3g at the breeding stage of small ponds; 5g at the breeding stage of medium and large ponds.

[0029] The application method is the same as in Example 1.

Abstract

The present invention discloses the application of L-arginine, L-ornithine and L-citrulline as spirulina princeps growth regulator, and aims at promoting the growth of spirulina princeps for cultivating spirulina princeps, L-arginine, L-ornithine or L-citrulline is added into culture liquid to speed the growth of spirulina princeps, raise the yield of spirulina princeps. Test shows that adding L-arginine, L-ornithine or L-citrulline in 0.2-5 g / L into the culture liquid can raise the yield of spirulina princeps by 8-52 % and speed the growth of spirulina princeps by 10-20 %.

Description

(1) Technical field [0001] The present invention relates to the application of L-arginine, L-ornithine or L-citrulline as a growth regulator of spirulina. (2) Background technology [0002] L-arginine, L-ornithine and L-citrulline play an important role in the growth process of the human body and participate in many physiological processes: such as ammonia metabolism in the liver, sperm formation, wound healing and immunity System maintenance, etc. L-arginine, L-ornithine, and L-citrulline have irreplaceable effects on the growth and development of human and animal immune organs and immune cells, as well as the secretion of related hormones such as pancreatic hormones, adrenal hormones, and pituitary hormones. effect. In addition, they can also treat mental retardation, dilate arterioles, and prevent thymus degeneration, among other functions. It can thus be said that L-arginine, L-ornithine or L-citrulline are animal growth regulators. But what about L-arginine, L-ornit...
