Microorganism having an ability to elute rare earth element, elution method of rare earth element, microorganism having ability to solidify rare earth element and solidification method of rare earth element

摘要

The present invention addresses: the problem of acquiring a microorganism that has an ability to selectively elute a rare earth element contained in a low-grade mine waste material, etc. and providing a method for collecting the rare earth element with a high resource value by using the microorganism; and the problem of identifying a novel microorganism that has an ability to solidify a rare earth element and providing a method for solidifying the rare earth element by using the microorganism. Provided are: a microorganism or mixed microorganisms that have an ability to elute a rare earth element from a rare earth element-containing mineral or a rare earth element-containing waste material; and a microorganism that has an ability to solidify a rare earth element.
