Eight bacteria and 8 fungi possessed solubilizing ability. Pseudomonas cepacia and Penicillium purpurogenum showed the highest activity. There was a correlation between final pH value and titratable acidity (r = - 0.29 to -0.87) and between titratable acidity and soluble phosphate (r = 0.22 to 0.99). Correlation values were functions of insoluble phosphate and of the group of microorganisms considered. A high correlation was observed between final pH and soluble phosphate only for the rock phosphates inoculated with the highest concentration of solubilizing bacteria (r = -0.73 to -0.98).567-572engBacteriafungirock phosphatesolubilizationFactors determining rock phosphate solubilization by microorganisms isolated from soilArtigo10.1007/BF00327716WOS:A1996VP45200002Acesso restrito2-s2.0-0030477447
