高磷贫碳酸锰矿石微生物的脱磷机理

The Mechanism of Biodephosphorization of Phosphorus-rich Rhodochrosite-poor

采用生尘芽孢杆菌对高磷贫碳酸锰矿石进行了微生物脱磷试验，探讨了其作用机理。结果表明，微生物脱磷过程主要是细菌代谢产物对难溶磷酸盐的解离作用和细菌的过量摄磷作用。

Dephosphorization of phosphorus-rich rhodochrosite-poor by Bacillus pulvifaciens has been investigated, the mechanism of biodephosphorization have been discussed. The result of researches show that the main processes of dephosphorization are the uptake of by microorganisms and dissociating function of the apatite by the metabolic products of microbes.
