Embodiment 1

[0059] Embodiment 1 stacked kudzu rice thin-layer culture device

[0060] Such as figure 1 As shown, in this example, the culture device includes a plurality of culture plates 1 distributed in layers, culture plates 1 ( figure 2 ) comprises a base plate 11 and a cofferdam 12 closely connected with the base plate 11 around the base plate 11, the cofferdam 12 is about 1-20mm higher than the base plate 11, and the base plate 11 and the cofferdam 12 form a cultivation space for Gexianmi, and two culture plates are adjacent to each other up and down 1 with a predetermined distance between them.

[0061] There is a support member 2 between two upper and lower adjacent culture plates 1 , and the support member 2 forms the predetermined distance between the upper and lower adjacent culture plates 1 . In this example, the support member 2 is a support column. The upper and lower two adjacent culture plates 1 are supported by a plurality of support columns, and the top and bottom en...

Embodiment 2

[0065] Embodiment 2 Gexianmi thin-layer static culture and comparison with traditional culture methods

[0066] In order to show the beneficial technical effects of the cultivation method and cultivation device of the present invention, the following four are directly related to industrialization benefits: "productivity per unit area of ​​light source", "energy consumption per unit mass of algal powder", "cost" and "water consumption per unit light source area" The factors are investigated and verified by experiments.

Abstract

The invention provides a culture method and culture apparatus for common nostoc, belonging to the field of microalga culture technologies. The culture method comprises a step of subjecting common nostoc to static culture in a thin-layer culture solution so as to allow the common nostoc to directly utilize CO2 adsorbed on the surface of the thin-layer culture solution. The culture apparatus is a laminated microalga thin-layer culture apparatus. The culture method and culture apparatus provided by the invention can increase biomass output per unit area of a light source. Energy consumed in carbon supply, stirring and the like can be omitted through thin-layer and static culture, so unit cost is effectively lowered.

Description

technical field [0001] The invention belongs to the field of algae biological cultivation, and relates to a cultivation method and a cultivation device of Gexianmi. Background technique [0002] Nostoc sphaeroides Kützing is a multicellular cyanobacteria belonging to Nostoc, and its scientific name is Nostoc pseudosphaeroides. Gexianmi is a kind of edible blue-green algae, named after Ge Hong, a Taoist theorist, medical scientist and alchemist in the Jin Dynasty and his experience. It is also recorded in the Compendium of Materia Medica that it has the effect of treating night blindness, rectal prolapse and other diseases. Wild kudzu rice is also rich in protein, exopolysaccharide and various trace elements. Its protein content is as high as 52% and its amino acid is complete. It also has a total sugar content of about 20% (including biologically active polysaccharides as high as 8%-12 %), so it can be widely used in food, medicine and health care and other fields; now many...
