| 摘 要： | 从沈阳石佛寺自来水厂除锰滤池中分离得到7株能够催化Mn2+氧化的细菌，并就催化因子的分离作了尝试．结果表明，Mn2+诱导催化氧化能力，催化活性因子在细胞上；培养基中的有机物浓度影响活性表达，有机物浓度升高，细菌生长加快，但活性表达被抑制．

| Abstract: | Seven strains of bacteria which catalyzed Mn2+-oxidization were isolated from the Mn-removing filter of Shifosi Water Plant in Shenyang of China. Morphology and the result of the stain of these bacteria are descrided and the isolation of catalyzing factors is also discussed in this paper. The oxidizing activity was induced by Mn2+, the substrate. The catalyzing factor is located on the cell instead of being excreted into culture medium. Organic carbon source (peptone, glucose) was necessary for the growth of the bacteria. When the concentration of organics was raised to more than 0. 5%, thebacteria grew faster but the activity of the bacterium oxidizing Mn2+ was inhibited. |
