Paper Title:
Explore the Effects of Magnetic Field Intensity Change on Acidithiobacillus ferrooxidans Growth and Magnetism
  Abstract

All the times we study a lot about Acidithiobacillus ferrooxidans (A.f) in mineral leaching, but when it is discovered that it can synthesize magnetosomes(Ms) in its body, researchers start to pay attention to its synthesis mechanism of Ms, while there is still few studies about the influence to A.f by external environment change. This article mainly aims at exploring the influence on A.f growth and magnetism under the outside magnetic field strength change. The findings show that not all A.f can synthesize magnetic substance. Under the most primary culture, there are few thalli can synthesize Ms; magnetic field at about 5mT, 10mT may promote thalli growth (quantity); magnetic field at about 25mT and 30mT may be harmful or beneficial to thalli response to time length; magnetic field at about 15mT, 20mT, 35mT, 40mT, 50mT may restrain thalli growth and reduce thalli activeness.
