METHOD FOR ENRICHING AND SEPARATING ANAEROBIC FIBER-DEGRADING BACTERIUM ON THE BASIS OF CELLULOSIC MAGNETIC NANOPARTICLES

摘要

A method for enriching and separating an anaerobic fiber-degrading bacterium on the basis of cellulosic magnetic nanoparticles. The cellulosic magnetic nanoparticles are prepared by coating cellulose on the surface of a magnetic nanomaterial. Bacteria attach to the cellulosic magnetic nanoparticles. Anaerobic fiber-degrading bacteria degrade the cellulose and then detach from the cellulosic magnetic nanoparticles, and the anaerobic fiber-degrading bacteria are obtained by means of separation using a magnet. The magnetic nano-separation technology can be used as a new technology to efficiently separate anaerobic fiber-degrading bacteria. The method for enriching and separating an anaerobic fiber-degrading bacterium has the advantages of rapid and efficient separation speed, convenient operation, low equipment costs, high bacteria capturing efficiency, a wide bacteria enrichment range, not being limited to a certain species of bacterium, high sensitivity, highly accurate results, and potential industrial applications.
