铁氧化菌去除Fe^(2+)条件的探究

Study on Fe^(2+) Removing Conditions of an Iron-oxidizing Bacterium

对1株分离自福州地下水的铁氧化细菌的生长曲线及Fe2+去除曲线进行测定,并进一步分析不同条件对Fe2+去除效果的影响.结果表明:温度22～28℃,pH值7～8,装液量为250 mL三角瓶装20～60 mL培养液,Fe2+小于50 mg/L时,该菌株对Fe2+的去除效果最好.

A iron-oxidizing bacteria isolated from the groundwater of Fuzhou was showed its growth curve and removal curve of Fe^2＋.Experiments were accessed to analyse the removal efficiency under different conditions.The results showed that the best removal efficiency results were achieved with 20～60 mL cultivation liquid（250 mL capacity erlenmeyer flasks）,at 22～28 ℃,whill the pH range 7～8,the Fe^2＋ concentration less to 50 mg/L.
