Abstract
Phytase is one of the identified enzymes which plays a vital role in phosphorous (P) cycle by mobilization of immobilized P from plant material. Although there is various phosphate solubilizing biofertilizer agents reported, they are majorly targeted for mobilizing rock phosphates in soil. The Phosphate solubilizing biofertilizers are required for mobilizing the immobilized form of P from plant source i.e., from phytate. The protocol is based on the principle that specific phytate agar medium contains calcium/sodium phytate, which is utilized as P source by phytase producing microorganism indicated by zone of clearance around the colony. The further quantification is executed by measuring the free phosphate by spectrophotometric method.
