Phosphorus (P) is one of the essential macronutrients making up about 0.2% of plant dry weight. At the same time, it is the most limiting macronutrient after nitrogen for plant growth. On the occurrence of abiotic stress, the availability and uptake of phosphorus for the plants further decrease. There are diverse groups of plant and soil-associated microbes which possess the ability to release phosphates from sparingly soluble mineral phosphates. Thus, they play major roles in providing the plants with phosphorus. P-solubilizing microbes have been isolated and reported from stressed environments which included diverse genera of Acinetobacter, Aspergillus, Bacillus, Penicillium, Pseudomonas, Streptomyces, and Trichoderma. The use of P-solubilizers as bioinoculant in agricultural systems is an important approach to circumvent the application of harmful chemical fertilizers. The implementation of novel technologies is important for the development of P-biofertilizers.
