ABSTRACT

The paper deals with measuring the magnetism of the metabolic products of Acidithiobacillus ferrooxidans bacteria that come from acid mine water accompanying
mining and processing of mineral resources. The aim of the paper is to characterize the
precipitates produced by the bacteria by means of magnetic quantities using a Vibrating
Sample Magnetometer (VSM), which helps to identify the magnetization of substances
in dependence on the external magnetic field. The results are related to the metabolic
activity and vitality of the bacteria.

Keywords: metabolic activity, hysteresis, magnetization, susceptibility
