Problems solved by technology

However, many enterprises at home and abroad are cultivating and developing spirulina. During the breeding process, changes in regions, seasons, and daily temperature differences have a great impact on the growth of algae and the accumulation of nutrients, but no growth environment has been found to affect the nutrition of spirulina. Reports on the accumulation of elements

Embodiment 1

[0034] 1) Inoculate Spirulina into Z's medium, after inoculating Spirulina, the OD of algae liquid 560 The value is 0.3. Cultivate for 3 days at 30°C, 12klx, pH=9.5.

[0035] 2) Continue culturing the spirulina cultured in step 1) for 3 days, adjust the temperature to 20°C, control the light at 12klx, and control the pH at 8.5, and add exogenous calcium CaCO to the medium 3 To a final concentration of 0.6g / L, cultivated for 3 days to obtain calcium-rich spirulina (calcium element content in spirulina is 2.52mg / g). The organic degree of calcium is 53.57%. Spirulina growth rate K=0.0465.

Embodiment 2

[0037] 1) Inoculate Spirulina into Z's medium, after inoculating Spirulina, the OD of algae liquid 560 The value is 0.3. Cultivate for 3 days at 30°C, 12klx, pH=9.5.

[0038] 2) Continue culturing the spirulina cultured in step 1) for 3 days, adjust the temperature to 20°C, control the light at 12klx, and control the pH at 8.5, and add exogenous calcium CaCO to the medium 3 To a final concentration of 0.6g / L, cultivate for 5 days to obtain calcium-rich spirulina (calcium element content in spirulina is 5.64mg / g). The organic degree of calcium is 72.14%. Spirulina growth rate K=0.0448.

Embodiment 3

[0040] 1) Inoculate Spirulina into Z's medium, after inoculating Spirulina, the OD of algae liquid 560 The value is 0.3. Cultivate for 3 days at 30°C, 12klx, pH=9.5.

[0041] 2) Continue culturing the spirulina cultured in step 1) for 3 days, adjust the temperature to 20°C, control the light at 12klx, and control the pH at 8.5, and add exogenous calcium CaCO to the medium 3 To a final concentration of 0.6g / L, cultivated for 7 days to obtain calcium-rich spirulina (calcium element content in spirulina is 18.21mg / g). The organic degree of calcium is 84.17%. Spirulina growth rate K=0.0411.

Abstract

The invention provides a method for regulating and controlling accumulation of a spirulina nutrient element zinc element. The method includes the steps that 1) spirulina is inoculated into a medium, and is cultured for 3 days under the conditions that the temperature is 20 DEG C to 40 DEG C, the illumination intensity is 4 klx to 12 klx, and the pH is 8.5 to 10.5; 2) the spirulina in the step 1) continues to culture under the conditions that the temperature is 15 DEG C to 35 DEG C, the illumination intensity is 2 klx to 20 klx, and the pH is 8.5 to 11.0; the zinc element is added into an outersource in the medium, and is cultured for 3 days to 7 days, and the high-nutrient-element spirulina is obtained. According to the method, the content of the zinc element in the spirulina is increased, the nutrient element and organic matter in cells are combined, the excitation to the gastrointestinal tract is reduced, and the absorption and utilization rate of the human body is increased. The content of the zinc of spirulina cells cultured with the method is increased by 87% than the content of zinc of spirulina cells cultured with a traditional culturing method, and the organization degreeof the zinc is 58.28% in sequence.

Description

[0001] The present invention is a divisional application of the Chinese patent application with the application number CN201611267287.X and the title of the invention is "A Method for Regulating the Accumulation of Nutrient Elements in Spirulina". technical field [0002] The invention relates to the technical field of directional cultivation and extraction of biological cells, in particular to a method for regulating the accumulation of spirulina nutrient element zinc. Background technique [0003] In recent years, supplementation of nutritional elements has attracted more and more attention. According to the data of the third national nutrition survey, the calcium intake of Chinese people is only 20%-50%, the zinc deficiency rate of children is as high as 60%, the average rate of iron deficiency anemia in China is about 20%, about 2 / 3 Selenium deficiency areas. The traditional methods to solve these nutritional deficiencies are severe cases through drug treatment, mild ca...
