Abstract
Pisolithus tinctorius (Pers.) Coker and Couch is capable of mobilizing non-mobile phosphates. Organic phosphates are broken down enzymatically by the fungal surface acid phosphatases whereas poorly soluble phosphates are solubilized by the ability of the fungus to excrete protons and organic acids. The accumulation of phosphate in the form of insoluble polyphosphate stored in the vacuoles is positively correlated with the external available phosphate pool. The major cation linked to the stored phosphate polymers in this fungus is calcium.
