The invention relates to a fungus bacterial strain A-FuO3 which can remove metallurgical waste water from rare earth mines or recover rare earth elements from low-concentration rare earth lixivium. The fungus bacterial strain A-FuO3 disclosed by the invention is taxonomically named as Aspergillus oryzae. The fungus bacterial strain A-FuO3 disclosed by the invention is good in effect of adsorbing low-concentration rare earth ions, simple to operate, low in cost and easy to culture. Microorganisms as adsorbents can be regenerated and degraded, and are environmentally-friendly and pollution-free. The fungus bacterial strain A-FuO3 can be applied to reduce the waste water treatment cost, reduce the discharge of ammonia nitrogen, avoid the waste of rare earth resources, and facilitate the water purification and the soil remediation in mineral leaching regions, and is also adaptive to enriched rare earth in the low-concentration rare earth lixivium. 本发明涉及一种能够去除稀土矿山冶金废水或回收低浓度稀土浸出液中稀土元素的真菌菌株A?FuO3，本发明的真菌菌株A?FuO3分类学命名
