Immobilized algae-bacterium spheres and preparation method and application thereof

Abstract

The invention relates to immobilized algae-bacterium spheres and a preparation method, a culture method and an application thereof. The immobilized algae-bacterium spheres are composed of chlorella pyrenoidosa, photosynthetic bacteria and embedding materials. The preparation method of the immobilized algae-bacterium spheres mainly comprises the steps of adding dropwise the cultured chlorella pyrenoidosa and photosynthetic bacteria into a sodium alginate solution according to a certain ratio, performing full stirring with a glass rod so as to enable the materials to be uniformly mixed, adding dropwise the obtained mixture into a calcium chloride solution, and performing cross-linking to obtain the immobilized algae-bacterium spheres. The prepared immobilized algae-bacterium spheres by the invention are good in effects of purifying aquaculture discharged water, and have purifying functions of algae and bacteria, double purification effects, and certain density and mechanical strength, and is not easy to break, and easy to sink to the water bottom, and can play a better purification effect. The invention further provides a continuous cultivation mode of the immobilized algae-bacterium spheres, which is simple and easy to operate, low in cost, and can realize large-scale industrial production.

Description

technical field [0001] The invention relates to an immobilized algae ball and its preparation method and application. Background technique [0002] With the growth of the world's population and the development of science and technology, fishery resources that were once called "inexhaustible" have become increasingly scarce. In order to meet human demand for high-quality protein, major fishery countries have paid more attention to aquaculture, making it quickly become one of the fastest-growing industries in the world's food production. In particular, my country's aquaculture industry has seen the fastest growth in global animal food production in recent years. However, due to a series of problems such as a large amount of bait input, a large amount of medication and a large number of water changes in the breeding process, the pollution of the aquaculture water environment has become increasingly serious, the deterioration of the aquaculture environment has caused frequent d...
