Multi-heavy-metal-resistant efficient cadmium-removing bacteria stenotrophomonas sp. CD2 and application of stenotrophomonas sp. CD2

The invention discloses efficient cadmium removal bacteria stenotrophomonas CD2 with multiple heavy metal resistance and application, and belongs to the technical field of environmental microorganisms. The cadmium removal bacterium Snotrophomonas sp. CD2 disclosed by the invention is preserved in the China Center for Type Culture Collection (CCTCC) on July 20, 2023, and the preservation number is CCTCC NO: M 20231348. The cadmium removal bacterium Snotrophomonas sp. The stenotrophomonas CD2 can efficiently remove Cd (II) under various conditions such as acidity, alkalinity, high salt concentration and existence of other heavy metals, and Zn (II) can promote removal of Cd (II) by strains. The stenotrophomonas stenotrophomonas CD2 is expected to be applied to various different types of cadmium pollution environments, and plays an important role in purifying cadmium pollution. 本发明公开了一株多重重金属抗性的高效镉去除菌窄食单胞菌CD2及用途，属于环境微生物技术领域。本发明的镉去除菌窄食单胞菌(Stenotrophomonas sp.)CD2于2023年7月20日保藏在中国典型培养物保藏中心(CCTCC)，保藏编号为CCTCC NO：M 2023
