Culture medium capable of promoting growth of desert alga and method for culturing growth of desert alga by adopting culture medium

Abstract

The invention relates to the technical field of culture media of desert alga, and provides a culture medium capable of promoting the growth of desert alga and a method for culturing the growth of thedesert alga by adopting the culture medium. In the culture media, soluble salt ions comprise Na+, K+ and Mg<2+>, and the concentration of the soluble salt ions is 10<-6>mM to 10<-2>mM. The method forculturing the growth of the desert alga comprises the following steps: inoculating activated desert alga cells to the culture medium of the desert alga, and carrying out static culture on the culturemedium under the light condition, wherein during static culture, a small amount of the culture solution is taken from the culture medium each day, when the number of cells of the desert alga or the optical density value at 540nm of the culture solution is measured to be stable, the culturing of the desert alga is completed. According to the technical scheme, the culture medium capable of promotingthe growth of the desert alga is obtained through allocation, so that an excellent method for culturing the growth of the desert alga is obtained, the number of the cells of the desert alga is improved by 30%-50% compared with the prior art, the yield of the desert alga is effectively improved, and the large-scale culture of the desert alga is facilitated.

Description

technical field [0001] The invention relates to the technical field of desert algae culture medium, and relates to a medium for promoting the growth of desert algae and a method for cultivating the growth of desert algae. Background technique [0002] Desert algae refers to a type of algae isolated from desert soil and artificially cultivated purely. Because its habitat is a harsh desert environment, people are accustomed to collectively refer to this type of algae as desert polar algae. Biological and nutritional studies on desert algae cells have found that such cells not only have unique nutritional characteristics, but also have a very ancient developmental status in biological evolution, which fully demonstrates that the Taklamakan Desert was once a vast ocean. With the disappearance of the ocean, the seaweed gradually evolved into today's desert algae. Desert algae is a specific ecological group of terrestrial algae, mainly referring to algal organisms that grow in de...

AI Technical Summary

Problems solved by technology

At present, the autotrophic culture technology of desert algae has been mature, but with the continuous proliferation of cells, the light entering the culture is blocked, resulting in weakened photosynthesis, which limits the further increase of its biomass, and the number of desert algae cells obtained Low, so that the yield of desert algae is not high
