磁选育浸矿菌种新方法的研究--磁黄铁矿选育菌种初探

here are three main species of the sulfide bioleaching bacteria. The key of raising the bio-leaching rate is how to screen the strain and improve the genetic specificity. It is a common method to screen great efficient bioleaching bacteria that to use minerals as culture medium. Pyrrhotite is usually used as mineral culture medium for including Fe and S element. The replacement of Fe atom by Ni, Co, Mn and Cu atom in the pyrrhotite space lattice made the Fe/S and magnetic different. Therefore, the different magnetic pyrrhotite can be separated by magnet and used as mineral culture to screen bioleaching bacteria, which is the best bacteria to bioleaching the different magnetic pyrrhotite. The growth condition of bacteria is analyzed and researched in the different magnetic pyrrhotite culture, domesticated the origin bacteria and gained several active bacteria with fast oxidation of Fe2+. The results show that it is a new efficient methods to screen bioleaching bacteria with using diffe
