摘　　要：研究绘制了相思根瘤菌MZ菌株和解磷菌217菌株在4种培养基中的OD值生长曲线,结果表明:它们都能在BSE培养基中较好的生长;对MZ根瘤菌和217解磷菌的常规培养基进行优化,获得了它们的优化培养基,进一步绘制的生长曲线证明了优化培养基更利于菌株的生长,且活菌数更多。217解磷能力的研究也表明:菌体数量与pH值、解磷强度之间有着密切的关系。The growth curves of MZ rhizobium and 217 phosphobacteria were drawn in four media in this study. The results showed that these two strains could both grow well in BSE medium. Based on the conventional media, the optimized media of MZ rhizobia and 217 phosphobacteria were obtained from orthogonal tests. Furthermore, the optimized media were testified to be more suitable for the growth of both of the strains, with more live bacteria, by the growth curves got afterwards. The tight relationship between pH level, phosphate-dissolving and bacterial growth ability was also discussed in the study on the phosphate-dissolving ability.
