Study on Effect Characteristics and Mechanism of <i>Sta</i><i>phylococcus aureus</i> on Albite

In order to more deeply understand the mechanism between microorganism and atmospheric inhaled mineral fine particles. Albite, the typical mineral fine particle in the atmosphere, was used as the research object. This study investigated the air common bacteria- Staphylococcus aureus acted on albite for 7 days. By inductively coupled plasma (ICP), zeta potentials analyzer, fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) testing means, we can analyse soluble ions, surface charge, surface groups and surface morphology of albite. The results were listed as followes: 1 Staphylococcus aureus could promote the dissolution of albite, and promote the soluble Si, Al and Fe ions; 2 Staphylococcus aureus would adsorb on albite surface, gave its some characteristics to albite, changed surface charge, and made the zeta potential move in the positive direction. The above results are important for the establishment of the inhaled fine particles of mineral environmental and health impact assessment system.
