Plant growth promoting rhizobacteria (PGPR) are introduced and used in agro-ecosystems to improve plant–microbe interactions, which can affect ecosystem sustainability, agricultural productivity, and environmental quality. Microbial inoculants are being explored internationally to make the important ingredient for plant bioavailability under the current scenario of P restrictions to crop plants. Because P can be found in both organic and inorganic forms in soils, researchers should look for microbes that can solubilize both pools of P at the same time. Phosphorus (P) is one of the most critical minerals for plant growth, and it ranks high among the soil macronutrients. Phosphate fertilisers are frequently used to compensate for soil P shortage. P deficit in soils is caused by lower total P levels in the soil and the inability to fix additional P from chemical fertilisers and other organic sources such as manure. The plant's response to P stress, or even when it is present in sufficient amounts, is relatively modest. The availability of P is limited by its solubilization, as it is fixed in both acidic and alkaline soils. Only phosphate-solubilizing bacteria can dissolve soil-fixed P. (PSMs). According to the literature examined, bacteria that exhibit numerous plant growth boosting properties rather than a single attribute should be picked during screening and selection procedures. Phosphatase activity, plant growth regulator production, and/or ACC-deaminase activity are examples of numerous characteristics. This method of identifying effective PGPR for enhancing nutrient availability for plant uptake could be more effective .
