[Objective] Multipurpose bioorganic fertilizers contribute to the sustainable development of the Carya cathayensis Sarg. industry. This work aims to explore the resources of phosphorus (P)-mobilizing bacteria (PMBs) with plant growth-promoting effects from the rhizosphere soil of C. cathayensis Sarg. [Methods] PMBs were isolated with the dilution-plate coating method and identified based on 16S rRNA gene homology. Moreover, plate and liquid culture tests were conducted to determine their biological functions. [Results] A total of 34 strains of PMBs were isolated from the rhizosphere soil of C. cathayensis Sarg. These PMBs belonged to 10 genera of four phyla: Bacillota, Proteobacteria, Actinobacteriota, and Gracilicutes. Among them, Bacillus (12 strains), Burkholderia (9 strains), and Pseudomonas (5 strains) were the dominant genera, with the strains accounting for 76.47% of the total isolated PMBs. After inoculation of PMBs, the content of soluble P produced by PMBs was 7.01–49.97, 3.61–27.11, 4.56–342.82, 27.71–544.53, and 3.28–27.17 mg/L in the culture media with AlPO4, FePO4, Ca3(PO4)2, sodium phytate, and lecithin as the sole P source, respectively. Twenty-three strains were capable of simultaneously mobilize insoluble inorganic and organic P components. Additionally, 20, 7, 23, 12, 10, 14, and 13 strains of PMBs could produce indole-3-acetic acid (IAA), siderophores, extracellular protease, β-1, 3-glucanase, cellulase, phosphatase, and lipase, respectively, among which strains S3-6L and S3-22L exhibited five biological functions. [Conclusion] The PMBs identified in this study possess high P mobilization capability and multiple biological functions, enriching the resources of PMB strains and laying a foundation for the development of efficient, green, and composite microbial fertilizers for C. cathayensis Sarg.
