溶磷微生物的选育及除磷研究

Study on Screening of Phosphate-solubilizing Microbes and Their Ability of Phosphorus Removal

从土壤中选育分离出8株溶磷微生物,研究了不同溶磷微生物对磷酸钙的溶解能力,其中菌株XH2对磷酸钙的溶解量最高可达415.69 mg/L。将溶磷微生物应用到高磷鲕状赤铁矿的除磷试验中,结果表明,菌株XH3的除磷最高达到79.58%的理想效果,为高磷铁矿石的脱磷技术提供了新的选择。

Eight phosphate-solubilizing microbes were isolated from soil,and different solubilizing ability of microorganisms on the dissolution of calcium phosphate has been studied,strain XH2 dissolved calcium phosphate up to 415.69 mg/L. In experiments of phosphorus removal from high phosphorus oolitic hematite,the phosphorus removal rate of strain XH3 reached up to 79.58%,which is a desired effect.The results of this study for high phosphorus iron ore dephosphorization technology provide new options.
