Factors affecting solubilisation of insoluble phosphates Physical factors
Temperature Optimum temperature for Pseudomonas striata is 20-30°C. For fungi the temperature is 30°C. Solubilisation is drastically reduced at high temperatures.

Aeration There is significant increase in rock phosphate solubilisation in shake cultures than in static cultures of P.striata and Aspergillus awamori. This explains the importance of aeration.

Incubation period Under cultural conditions, phosphorus solubilisation takes up to 10-15 days. Generally solubilisation increases with incubation period.
