Analysis on Iron-Oxidizing Bacteria and Their Influencing Factors in Water and Soil Environment of Sewage Irrigation Area in
Iron-oxidizing bacteria were cultured and analyzed by the change of the number of iron-oxidizing bacteria in the soil and water and its relationship between environmental factors. This paper indicates that the best aqueous environment for the growth of iron-oxidizing bacteria in the study area is pH =7.4, showing in the alkaline and neutrality condition. The result shows that the shallow groundwater and the surface soil (depth <
