Summary: Soil microorganisms play a crucial role in maintaining ecological balance, particularly through their involvement in nutrient cycles. Phosphate-solubilizing bacteria (PSB) are of particular importance in the rhizosphere and can be used as biofertilizers in agriculture. This study identified five species of PSB, including Pseudomonas fluorescens, P. putida, P. taiwanensis, Stenotrophomonas maltophilia, and Pantoea agglomerans, through genetic sequencing. The PSB isolates exhibited varying degrees of phosphate solubilization, with P. fluorescens showing the highest solubilization ability. Additionally, all five PSB species were capable of producing the growth-promoting hormone indole acetic acid (IAA), with P. fluorescens producing the highest quantity.

Summary: This study examined the effects of three levels of bio-fertilizers (none, arbuscular mycorrhizal fungi (AMF), and phosphate solubilizing bacteria (PSB)) and three levels of phosphorus fertilizer dose on barley yield and nutrient uptake under saline soil conditions. The findings showed that the combination of AMF with 100% RDP significantly improved plant height, spike length, spike weight, number of spikes per plant, weight of 1000 grains, straw yield, grain yield, and uptake of nitrogen, phosphorus, and potassium.

Summary: The phosphate-solubilizing bacteria (PSB) isolated from the rhizosphere of intercropped soybean have the potential to promote plant growth by secreting organic acids and enhancing plant P uptake. Inoculation of PSBs significantly increases soil acid phosphatase activity and available P content.

Summary: This study assessed the solubilization capacity of PSB strains isolated from phosphate solid sludge in different forms of inorganic phosphates. The results showed that all strains were able to solubilize the three different forms of phosphates, but there were variations in their solubilization abilities.

Summary: This study develops microbial inoculants using inorganic phosphate solubilizing bacteria (iPSB) in paddy field soils, which is important for agriculture. The isolation of iPSB is influenced by different fertilizer management and soil types. Most of the isolates belong to ss-Proteobacteria. Furthermore, the genera Pleomorphomonas, Rhodanobacter, and Trinickia are identified as iPSB for the first time in this study.

Summary: This study investigated the effects of using phosphate-solubilizing bacteria (PSB) liquid fertilizer prepared from food wastewater (FWW) on soil fertility and Pakchoi growth. The results showed that the PSB fertilizer significantly improved the growth of Pakchoi and soil fertility by increasing the concentration of available phosphorus and catalase activity. The dominant bacterial phyla in the rhizosphere were positively associated with phosphatase, catalase, and the growth indices of Pakchoi.

Summary: The present study aimed to design a biofertilizer using phosphate solubilizing bacteria (PSB) and locally produced fruit waste. The evaluation of the prepared compost revealed that it was safe, beneficial for soil fertility, and could be used as a phosphatic biofertilizer. This study encourages the use of PSB-rich compost to improve and sustain soil fertility.

Summary: This study aims to investigate the impact of phosphate-solubilizing bacterial inoculation on maize growth, soil characteristics, P fractions, and the soil microbial community. The results showed that inoculation with XQP35 and SQP80 enhanced maize biomass and improved the soil nutrient status. Furthermore, the inoculation promoted the transformation of P fractions and increased soil available P content.

Summary: This review discusses the use of silicon, phosphate-solubilizing bacteria, and arbuscular mycorrhizal fungi to improve phosphorus availability in deficient soils. The combined strategy of using silicon with both microorganism groups may be highly useful in enhancing phosphorus uptake by plants. Understanding the interactions among these components is crucial for sustainable agriculture practices.

Summary: Soil microorganisms, especially P-solubilizing microorganisms (PSMs) of the genus Bacillus, can increase the availability of phosphorus for plants. In this two-year study, the ability of PSMs to release soluble P from apatite concentrates was evaluated using ryegrass as a model plant. The combination of specific Bacillus strains and standard grinding apatite concentrate had the greatest effect on plant growth and biomass accumulation.

Summary: Phosphorus (P) is a vital macronutrient for all life on Earth and plays a crucial role in plant growth and yield. However, P deficiency is a common problem in terrestrial ecosystems worldwide. The use of chemical phosphate fertilizer has limitations due to its non-renewable raw materials and adverse effects on the environment. Therefore, finding alternative strategies, such as phosphate-solubilizing bacteria (PSB), to meet plant P demand is important. This article reviews the biogeochemical P cycling in soil systems, explores the use of PSB to alleviate global P resource shortage, discusses the advances in multi-omics technologies, and analyzes the multiple roles of PSB inoculants in sustainable agricultural practices. The authors propose that further research is needed to better understand the interactive mechanisms between PSB, rhizosphere microbiota, and plants in order to maximize the efficacy of PSB as P activators.
