The Reciprocity between Atmosphere Dusts and S. epidernidis

In order to compare the chemical compositions and physical characteristics of different atmosphere dusts on S. epidernidis, chemical compositions of five kinds of atmosphere natural dropping dusts have been analyzed and the changes of pH value, glucose (GLU), electrolyte before and after the dusts reacted with S. epidernidis have been measured. The SEM analysis has been used to study the bacterial surface morphology and interface action status in the course of reaction between dusts and bacteria. The results illustrated that Major chemical composition of atmosphere dusts and dissolution quantity of ions after the aced with S. epidernidis were different. The atmosphere dusts containing high Ca²⁺ or Mg²⁺ could increase the number of S. epidernidis and the use quantity of GLU. The dust granules´ adhered degree is increasing with the granularity´s decreasing, and the abnormity figure could increase the adhering degree between the bacterial membranes and dust surfaces.
