Climate change significantly impacts plant growth by reducing the availability of essential nutrients, including phosphorus (P). As an alternative to chemical fertilizers, climate-smart agriculture should prioritize use beneficial microorganisms such as P-solubilizing bacteria (PSB). Here, we report ability P1.5S strain Bacillus safensis solubilize P under stress caused different pH, temperature, and salinity. Genomic data TBLASTN algorithm were used identify genes involved in tolerance solubilization. Stress was confirmed cultivation varying conditions, while mechanism solubilization investigated using HPLC. Bioinformatic analysis revealed at least 99 related tolerance, 32 responsible for organic acids synthesis, well 10 phosphatase production. B. can grow 37 °C, high NaCl concentrations (15 g/L), is tolerant alkaline acidic conditions. The primarily solubilizes releasing acids, lactic, acetic, succinic acid. Our that efficacy not affected abiotic stressors (19.54 µg P/mL). By evaluating induced represented salinity this work introduces a new avenue increasing availability, which enables endorses future development practical applications challenging agricultural environments.
