2种担子菌对磷矿中磷的浸提效果

Leaching effect of two species of basidiomycetes to phosphorus in rock phosphate

研究木蹄层孔菌和桦剥管菌发酵液对低品位磷的浸出效果。结果表明,木蹄层孔菌的解磷能力显著强于桦剥管菌。最佳浸磷条件为:(1)木蹄层孔菌:矿液比为1∶3,浸矿时间为4 d,初始pH 1.88,提取液中磷最大质量浓度为34.95 mg/L,最大提取率为1.6%。(2)桦剥管菌:矿液比为1∶3.5,初始pH为2.51,提取液中磷最大质量浓度为8.12 mg/L,最大提取率为0.24%。

The leaching effect of low-grade rock phosphate with the fermented liquors of Fomes fomentarius(L.∶Fr.) Kick.and Piptoporus betulinus(Bull.∶Fr.) Karst.was studied.Using monofactor experiment to study effect of different mine-liquid proportion,lixiviation time,and initial pH of fermentation broth to phosphorus leaching of cultures.Results showed that the capability of F.fomentarius was obviously stronger than that of P.betulinus.The optimum conditions being obtained in this study were:(1)F.fomentarius:mine-l...
