Abstract

The invention relates to economic microalgae research and development application, and aims at providing a separation method of a chlorella species for high production of polysaccharide. The method comprises the following steps: adding glycerol, rhamnose and vitamin C to a Basal culture solution, so that a culture solution HPSC-M of the chlorella species for high production of the polysaccharide is obtained; and separating epiphytic algae from stems of wild dendrobium officinale, and conducting pressure screening in a high-temperature dry environment, so that the chlorella for high production of the polysaccharide is obtained. The method disclosed by the invention, compared with a conventional breeding method, has the characteristics of being simple and convenient to operate, low in cost, free from special requirements on the professional skills of operators, strong in applicability and the like; and a necessary technical method is provided for chlorella breeding.

Description

technical field [0001] The invention relates to the technology for the research, development and application of economical microalgae, in particular to a method for separating high-yield polysaccharide chlorella species. Background technique [0002] Chlorella (Chlorella) is one of the economical microalgae with wide distribution, fast growth, and the largest scale of cultivation and application in the world. Polysaccharide is one of the important bioactive components of chlorella, which has remarkable effects such as regulating the body's immune ability, anti-tumor, anti-virus and anti-aging [1～4] . However, biologically active polysaccharides are generally secondary metabolites, and their content in organisms is generally low and their production costs are high, which severely restricts their in-depth research and further application [6-11]. [Breeding of a new strain of Chlorella with high-yield polysaccharides and its growth-promoting and immune-regulating effects on Pe...
