Abstract
A marine-derived nanoselenium-producing strain and a method for preparing nanoselenium by using the strain are provided in the present disclosure, belonging to the field of nano biomaterials. According to the present disclosure, a Bacillus strain capable of preparing nanoselenium is screened from sediments taken from the Arctic Ocean, named Bacillus sp. Q72, which has been deposit in the China General Microbiological Culture Collection Center, and the deposit number is CGMCC No.26355. The extracellular fluid of this strain is used to directly reduce high concentrations of sodium selenite to obtain selenium nanoparticles.
