【摘要】 所试的民养微生物能在静止状态含蔗糖和氧化铁的培养液中生长。它们在氧化蔗糖到CO2时，伴随着Fe3+还原到Fe2+、Fe2+移动到基质表面与O2接触后，又会氧化为Fe3+培养液Fe3+被还原的适宜pH和温度分别为7.0、25℃。若培养液中加入0．1％硝酸盐时，还原Fe3+的过程会停滞或减慢。更多还原

【Abstract】 The tested heterotrophic microbe can grow in the static liqued medium containing sucrose and ferric iron (Fe3+). These organisms oxidated sucrose to CO2, with the reduction of Fe3+ to Fe2+ When Fe2+ mobilis to the surface of the medium and contacts with O2, it can be reduced again. In the course of redox, optimum pH is 7.0, temprature is 25℃. If 0.1% KNO3 was added in the medium, the rate of Fe2+ formation will bogdown or lower.更多还原
