Solubilise and mobilise phosphorus.
B2655 has proven to solubilize inaccessible phosphorous in vitro, turning it accessible for plants and promoting their growth. B2655 produces, among others, alkaline phosphatase and acid phosphatase enzymes. These enzymes play an important role in solubilization of bound phosphates, making them available to plants (ability to solubilize phosphate). Moreover, B2655 is a nitrogen-fixing strain.
Pseudomonas lutea strain B2549 (1-2x10E10 CFU/ml), Azospirillum irakense strain B2655 (1-2x10E10 CFU/ml).
