description The invention discloses a biological nanomaterial with magnetism, a preparation method and an application thereof. The biological nanomaterial adopts saccharomyces cerevisiae in saccharomyces as carriers, and is loaded with nano Fe3O4 and a crosslinking product of chitosan and epichlorohydrin; the surface of the saccharomyces cerevisiae is wrapped with calcium alginate. The method comprises the following steps: firstly preparing the nano Fe3O4 and the crosslinking product of chitosan and epichlorohydrin, then mixing with saccharomyces cerevisiae spore liquid and a calcium alginate solution, dripping the mixed solution into a calcium chloride solution dropwise, and immobilizing to obtain nano Fe3O4-saccharomyces cerevisiae-calcium alginate microspheres, and culturing, thus obtaining a biological material with the magnetism. The biological material with the magnetism has the magnetism of the Fe3O4 and the microbial performance of the saccharomyces cerevisiae, has the advantages of good removing effect, easiness
