Production process of nostoc sphaeroides

Abstract

The invention discloses a nostoc strain preparing method, selecting culture collection, washing and sterilizing, evening pulp, inoculating and cultivating, and obtaining a large number of nostoc strains. Compared with existing techniques, it has the advantages: simple operation, making aseptic purification without antibiotic, short cycle of preparing strains, high efficiency, therefore it can form a large number of strains, and meet the demand on strain preparation.

Description

Technical field:

[0001] The invention relates to microalgae, and more specifically to a preparation method of the species of S. kudzui. Background technique:

[0002] Nostoc belongs to Cyanophyta Cyanophyta Cyanophyceae Cyanophyceae segmental algae Hormogonales Nostocaceae, a class of algae with wide distribution, complex ecological environment, and diverse morphological structures. Its plants are gelatinous or leathery, and mature plants have Spherical, leafy, filamentous, vesicular and other shapes, hollow or solid, floating or growing. The original plant consists of many fine filaments with a diameter of a few microns assembled into a group, and the shape of the group varies depending on the "species", such as Nostoc flageliforme Kütz., Nostoc commune, Nostoc sphaeroides In the fresh state, they are hair-like, flat ear-shaped or small ball-shaped respectively, and they shrink to varying degrees after drying, all of which have rich nutritional value. , "Wuzhou Fuzhi", "N...
