摘　　要：研究了一种芽孢杆菌代谢产酸的生化特性．考察了其在富磷、缺磷及含磷酸钙的缺磷培养基中的生长情况及摄磷、溶磷行为．结果表明：在富磷培养基中，细菌代谢产酸明显并能过量摄磷；在缺磷培养基中，细菌代谢受到抑制；在含磷酸钙的培养基中，细菌除能过量摄磷外，其代谢产生的酸具有显著的溶解磷酸钙作用．Studies the biochemical properties of bacterial acidgenerating. Uptake and dissolving of phosphorus by bacillus were investigated in three different media. The results show that in the phosphorusrich medium, the bacteria can accumulate phosphorus within their cells; in the phosphorusdeficient medium, the bacterial metabolism is inhibited;besides accumulating phosphorus extensively, the microbc can dissolve the calcium phosphate in condition of calcium phosphate as sole phosphorus source.
