Abstract

AbstractPhosphorus (P) availability in soil is often limited, posing a challenge for sustainable agricultural production. Phosphate solubilizing microorganisms (PSMs) have emerged as a promising biological approach to enhance soil P availability while minimize negative environmental impacts. Exploring the impact of PSMs on increasing soil available P is crucial for optimizing the utilization of insoluble P in soil and promoting sustainable agricultural practices. In this article, we provide a comprehensive review on the dynamics of soil available P, including its input, loss and transformation processes. Additionally, we draw a conclusion about how PSMs increase the availability of P in soil, including solubilizing inorganic P (Pi) and organic P (Po) by secreting substances such as protons, organic acids, inorganic acids, exopolysaccharides, hydrogen sulfide, siderophores and phosphatases. Notably, the factors influencing the P solubilizing activity of PSMs in soil are thoroughly discussed. Moreover, practical applications of PSMs for increasing soil P availability are summarized. Future research should focus on exploring novel PSM isolates, conducting long-term field experiments to assess the effects and potential risk of PSMs under diverse conditions, and investigating synergistic approaches with other P activators or beneficial microorganisms. This review will advance our understanding of PSMs and their practical application, enabling their widespread adoption in agricultural systems.Keywords: Potential riskpractical applicationsustainable agricultural production Author contributionsFeng Liu: Writing-original draft preparation.

增磷微生物提高土壤磷有效性的研究进展

摘要土壤中磷的有效性往往是有限的，这对农业可持续生产提出了挑战。磷酸盐增溶微生物(psm)已成为一种有前途的生物方法，以提高土壤磷有效性，同时尽量减少对环境的负面影响。探索土壤磷素对提高土壤速效磷的影响，对于优化土壤不溶性磷的利用和促进可持续农业实践具有重要意义。本文对土壤有效磷的输入、流失和转化过程进行了综述。此外，我们还得出了psm如何通过分泌质子、有机酸、无机酸、外多糖、硫化氢、铁载体和磷酸酶等物质来溶解无机磷(Pi)和有机磷(Po)的结论。特别讨论了影响psm在土壤中溶磷活性的因素。此外，还总结了psm在提高土壤磷素有效性方面的实际应用。未来的研究应侧重于探索新的PSM分离物，进行长期的现场实验以评估PSM在不同条件下的效果和潜在风险，并研究与其他P激活剂或有益微生物的协同方法。这一综述将促进我们对psm及其实际应用的理解，使其在农业系统中得到广泛采用。关键词:潜在风险实际应用可持续农业生产作者贡献刘峰:写作-原稿准备金谦:监管。朱跃明、王培芳、胡静:述评与编辑。陆汴河，何宇轩，唐思静:数据策展。沈俊伟，刘寅，李凤铎:可视化。作者声明没有潜在的利益冲突。本研究由国家自然科学基金资助[No. 5];51779078]，江苏省六大人才高峰工程项目[No. 51779078];国家水污染控制与治理技术重大专项[JNHB-012];2017ZX07204003]，江苏省高等学校重点学科建设项目(PAPD)。

期刊介绍： Geomicrobiology Journal is a unified vehicle for research and review articles in geomicrobiology and microbial biogeochemistry. One or two special issues devoted to specific geomicrobiological topics are published each year. General articles deal with microbial transformations of geologically important minerals and elements, including those that occur in marine and freshwater environments, soils, mineral deposits and rock formations, and the environmental biogeochemical impact of these transformations. In this context, the functions of Bacteria and Archaea, yeasts, filamentous fungi, micro-algae, protists, and their viruses as geochemical agents are examined. Articles may stress the nature of specific geologically important microorganisms and their activities, or the environmental and geological consequences of geomicrobiological activity. The Journal covers an array of topics such as: microbial weathering; microbial roles in the formation and degradation of specific minerals; mineralization of organic matter; petroleum microbiology; subsurface microbiology; biofilm form and function, and other interfacial phenomena of geological importance; biogeochemical cycling of elements; isotopic fractionation; paleomicrobiology. Applied topics such as bioleaching microbiology, geomicrobiological prospecting, and groundwater pollution microbiology are addressed. New methods and techniques applied in geomicrobiological studies are also considered.
