Bacterial capacities to mineralize phytate increase in the rhizosphere of nodulated common bean (Phaseolus vulgaris) under P deficiency

Abstract: Abstract Phytate (a form of Inositol phosphate), which is one of the most abundant sources of organic phosphorus (Po) in soils, needs to be mineralized by microbial phosphatases to become available for plants. Phytases are the most active phosphatases for the dephosphorylation of phytate but the ecology of the phytate mineralising bacteria (PMB) remains poorly understood. The aim of this work was to determine if PMB represent an important component of the rhizosphere of legumes and if their density and their activities ...
