Pollution controlling method in cultivating nostoc and nostoc commune

Abstract

The invention discloses a control method of pollution of nostoc and agaric culture mediums, firstly adopting pure cultivation in the strain production; secondly, before inoculating, washing culture tank and container; thirdly, washing or screening algae; fourthly, filtering the culture solution by gauze; fifthly, killing or eliminating planktons. It has simple and easy operation, high efficiency, convenient operation, low cost, able to effectively control the quantities of living pollutants in the culture solution within 1% during cultivating, and suitable to control production pollution in factories.

Description

technical field

[0001] The invention relates to the field of microalgae biotechnology, and more specifically relates to a pollution control method in the cultivation of Gexianmi and ground fungus. Background technique

[0002] Nostoc is a kind of algae group with wide distribution, complex ecological environment and various morphological structures in the cyanophyta Cyanophyta Cyanophyceae Cyanophyceae segmental algae order Hormogonales Nostocaceae. , leaf-like, filamentous, bubble-like and other shapes, hollow or solid, floating or growing. The protophyte consists of many fine filaments with a diameter of a few microns assembled into a group visible to the naked eye, and the shape of the group varies with the "species", such as Nostoc flageliforme Kütz., Nostoc commune, Ge Xianmi (Nostoc sphaeroides) are in the shape of hair, flat ears or small balls (beads) in the fresh state, and shrink to varying degrees after drying, all of which have rich nu...
