Summary: This study found that adding 10% or 15% rock phosphate promoted temperature rise, maturity improvement, and accumulation of dissolved phosphorus during composting. The efficiency of phosphorus solubilization was negatively correlated with the C:P ratio, and lower C:P ratios increased the solubilization ratio of rock phosphate.

Summary: In this study, the effect of different phosphate sources on the uranium biomineralization process mediated by Microbacterium sp. Be9 was investigated. It was found that the interaction mechanisms between the bacteria and uranium depended on the type of phosphate substrate. In the absence of exogenous phosphate substrate, the cells interacted with uranium through U phosphate biomineralization, achieving a 98% removal of uranium within 48 hours. However, in the presence of inorganic phosphate, the main interaction mechanism was uranium solubilization, demonstrating the phosphate solubilizing potential of the strain.

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.

Summary: The aim of this study was to investigate the solubilization of monazite and recovery of REE using Burkholderia thailandensis, and the influence of the rhamnolipids produced by the bacteria on REE mobilization. B. thailandensis grown in nutrient broth with 1% monazite (w/v) achieved a REE concentration of 8.3 mg center dot l-1 after 15 days. Rhamnolipids were produced by B. thailandensis grown in medium supplemented with 10% glycerol, and the critical micelle concentration (CMC) was determined to be 94.45 mg center dot l-1 for commercial rhamnolipids and 60.41 mg center dot l-1 for purified rhamnolipids. The maximum REE solubilization was achieved at CMC, with 9.36 mg center dot l-1 for commercial rhamnolipids and 5.13 mg center dot l-1 for rhamnolipids produced by B. thailandensis E264.

Summary: The study aimed to evaluate the phosphate-solubilizing efficiency of phosphate-solubilizing microorganisms (PSMs) using tricalcium phosphate (TCP) and Eppawala rock phosphate (ERP). A series of identified isolates were compared in phosphate solubilization using TCP and ERP as a P source. Twelve isolates with higher efficiency were selected for biofertilizer production. The pot trial with Capsicum annuum L. showed that the application of native PSMs as biofertilizer effectively increased plant height, leaf length, and width.

Summary: Rock phosphate is a natural source of phosphorus for agriculture, but its slow release can limit short-term availability to crops. P-solubilizing microorganisms were studied for their ability to improve P availability from rock phosphate. Genomic analysis of selected bacteria revealed genes related to P uptake and metabolism, showing potential for use as bioinoculants to improve rock phosphate solubilization and plant growth under field conditions.

Summary: This study investigated the effects of different aeration rates on phosphorus conversion and bacterial community dynamics in phosphorus-enriched composting. The results showed that an appropriate aeration rate enhances phosphorus solubilization efficacy and accumulation. Key bacteria such as Lactobacillus, Spartobacteria and Pseudomonas were closely associated with phosphorus solubilization. Increasing the aeration rate improves the connection and function similarity among modules, leading to an organized community organization for key bacteria to solubilize phosphorus. The study suggests that indirectly biotic phosphorus solubilization, mainly by phosphate-solubilizing bacteria, contributes more than directly biotic solubilization.

Summary: Soil microbes, such as Bradyrhizobium sp. LSBR-3 and Pseudomonas oryzihabitans LSE-3, were found to improve the symbiosis, nutrient accumulation, and yield of soybean. Dual inoculation with LSBR-3 and LSE-3 resulted in higher plant growth-promoting traits and significantly increased nodulation, phosphatase and dehydrogenase activities, and nutrient uptake in soybean.

Summary: The continuous application of phosphate mineral to soil leads to the addition of apatite during each crop growing season, which is a significant concern for sustainable agriculture. This study identified and characterized efficient phosphate solubilizing microbes from hydroxyapatite mines to solubilize apatite in the soil. Results showed that the isolated bacterial and fungal strains, particularly when combined with compost, increased plant phosphorus uptake and soil phosphorus content. This highlights the potential of efficient P solubilizers for sustainable agriculture by utilizing indigenous phosphate reserves of soil in combination with organic amendments.

Summary: Soil history plays a crucial role in shaping the structure and biodiversity of soil bacterial communities. This study evaluated the impact of different soil histories on the bacterial communities associated with five Brassicaceae host plants. The results showed that the Brassicaceae hosts consistently influenced the bacterial community structure, while the previous year's soil history only had a significant effect when the host plant feedback was weakened. Understanding soil history is essential for utilizing microbiome technologies to improve agricultural systems.
