The determination of specific phosphatmobilizing activity of soil microorganisms

The study aimed to compare the phosphate-mobilizing activity of 69 strains genus Bacillus on agar and liquid Muromtsev medium identify a possible correlation between them. Research methods: microbiological, laboratory-analytical, statistical. main results study. closeness relationships phosphates dissolving nutrient media by have been determined. There is no significant size dissolution zone phosphorus removal in culture fluid has found. However, coefficients specific indicators - (the ratio total quantity dissolved amount grown biomass) phosphamobilizing dimensions colony size) considerable: for first group = 0.603; second R 0.752; third 0.864; fifth group, 0.732. coefficient an average value (0.415) fourth includes with high (museum B. subtilis 54, 72, 101s, 100), as well new isolated from soil sp. D-31 D-32. close (R3 0,670) two indicators: (Kr) FMP (Asp.). (Analysis conducted taking into account all investigated bacilli). Conclusions. indicator use will simplify screening medium.
