Medium Optimization of Acacia Rhizobia and Phosphobacteria and the Study of Phosphate-dissolving Ability
Abstract: 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.
