Última Release of potassium from rock powder by the yeast Torulaspora globosa BABT Rosa-Magri,Márcia Maria; Avansini,Simoni Helena; Lopes-Assad,Maria Leonor; Tauk-Tornisielo,Sâmia Maria; Ceccato-Antonini,Sandra Regina. The alteration of minerals in rocks and the availability of elements for plant nutrition require long periods of time, and microorganisms are thought to induce the release of potassium and phosphate from rocks. In this context, this work evaluates the role of the yeast Torulaspora globosa, isolated from the sugar cane rhizosphere, in the solubilization of potassium from alkaline ultramafic rock powder. The experiments were performed in liquid medium, with or without agitation, at 30°C with the following treatments: culture medium + alkaline ultramafic; culture medium + yeast suspension; and culture medium + yeast suspension + alkaline ultramafic. The results showed that as much as 38% of the total potassium in the rock was released in the medium with the...

ABSTRACT Rock phosphate (RP) is traditionally solubilized by chemical process causing high cost and environmental pollution. To reduce process cost and protect environment, RP solubilization by Aspergillus japonicus was studied and its mechanisms were discussed. Results show that A. japonicus could effectively solubilize RP in NBRIP medium. RP solubilization by A. japonicus included direct and indirect actions of the strain on RP. Cells of A. japonicus attached rapidly to RP surface and the RP surface was seriously corroded by the strain. A. japonicus excreted multiple organic acids, and followed by a significant increase of titratable acidity and decrease of pH in the culture. A positive correlation between content of soluble phosphate and quantity of...
