Abstract

Several yeasts, fungi and bacteria isolated from the rhizosphere of leguminous crops and soils of rock phosphate deposit area were found to solubilize low-grade Mussorie rock phosphate. Of the several yeasts and fungi,Schawanniomyces occidentalis, Aspergillus awamori andPenicillium digitatum were better than others in rock phosphate solubilization. Among bacterial isolates from soils of rock phosphate deposits, Gram-negative motile rods were more effective than Gram-negative non-motile rods in dissolving rock phoshates. The most efficient bacteria were identified as strains ofPseudomonas striata. All the microorganisms acidified the liquid medium but there was no relationship between the rock phosphate dissolved and the decrease in pH of the culture broth.
