Effect of thermal power plant dusts to the growth of some body normal strains
(0) This paper studied the growth effect mechanism of thermal power plant dust on three body normal flora. The physics properities, major chemical composition and granularity distributing of the experiment dust were analysis and the change of number of index bacterial colonies, pH, glucose (GLU) and electrolyte relative to the controls were observed. And in the same time, we studied the bacterial form and interface act in the action process of dusts and bacteria through SEM analysis. The reciprocity of thermal power dusts and three body normal strains didn’t bring obvious change on the wastage of GLU, the number of bacterial colonies, pH value and the others electrolyte et al. Compare to the bacterial control groups, the concentrations of Ca2+and Mg2+increased 0.69mmol/L (P<0.05)and 0.16mmol/L (P<0.05) respectively. The bacteria colonies of Escherichia coli and Staphylococcus epidernidis increased 1×109 CFU/mL and 12×109 CFU/mL (P<0.05). Thermal power plant dusts of proper concentration have more obvious effect to the growth of Staphylococcus epidernidis than the other strains.
