Magnetotactic bacteria or magnetotactic microbe separator

Abstract

The invention relates the segregator, comprising permanent magnet components, cover (3), separating cap (4) and sample cap (5). In the separating cap (4) there is inner edge (6) which is connected with inner wall of separating cap (4); under interior extent (6) there is rubber ring (7), and between them there is filter paper; permanent magnet components comprises N magnet and S magnet; separating cap (4) is connected with sample cap (5). The invention solves the problem that the magnetic bacteria is not easy to separate, and the invention has the advantages of simple technology, low cost, easy usage and strong practicality.

Description

technical field [0001] The invention is a separator for magnetotactic bacteria or magnetotactic microorganisms, which is used for separating and purifying magnetotactic bacteria or magnetotactic microorganisms in scientific research and production applications. Background technique [0002] Magnetotactic bacteria (Magnetotactic bacteria) is a kind of bacteria that can form nano-scale magnetic particles - Magnetosomes (Magnetosome) in the body, and make directional movement under the action of an external magnetic field. Magnetosome particles synthesized in magnetotactic bacteria are a kind of natural magnetic nanomaterials (size between 30-120nm, the main component is Fe 3 o 4 and Fe 3 S 4 ), can be applied to high-tech fields such as information storage, biosensing technology, medical and health care, nano-medicine, electronics, communications, computers, etc. Japanese scholar Matsunaga predicted in 1991 that the magnetosomes of magnetotactic bacteria would be a new bio...

Problems solved by technology

[0004] As we all know, the vast majority of magnetotactic bacteria and some magnetotactic microorganisms are microaerobic or anaerobic, and it is difficult to separate and purify them. At present, conventional microbial separation methods such as enrichment culture and purification methods such as coating Separation and culture on plates, etc.

The magnetotactic bacteria culture solution obtained by enrichment culture is inevitably mixed with other microorganisms, so it is difficult to obtain a pure culture. Although the single colony of magnetotactic bacteria obtained by the repeated plating method has achieved the purpose of strain purification, it is very time-consuming , and magnetotactic bacteria easily lose the ability to synthesize magnetosomes

Therefore, the isolation and purification of magnetotactic bacteria (microorganisms) is a major problem in this research field. At present, there are very few strains that can be purely cultured, which seriously affects the research progress and application of magnetotactic microorganisms.
