磷是植物必需的营养元素之一。It is second only to nitrogen and is considered one of the most growth-limiting macronutrients of plants. Soil is rich in insoluble phosphates. But it is deficient in soluble phosphates, which can be absorbed by plants. Plants absorb phosphorus in the form of orthophosphate. Phosphorus deficiency severely restricts plant growth, development, and yield. In order to overcome P scarcity in the agricultural soil, phosphorus fertilizers are added. In fact, phosphorus is the second most applied nutrient in agriculture. Soil microorganisms play an essential role in the P cycling and phosphorus nutrition of plants. Some microorganisms participate in mineral phosphate solubilization and facilitate phosphate mobilization in the soil.

什么是磷酸盐溶解?
磷酸盐溶解微生物是有机和无机磷具有矿化和溶解潜力的微生物。磷溶解活性取决于微生物释放的能力metabolites如有机酸, through which their hydroxyl and carboxyl groups chelate the cation bound to phosphate, the latter being converted to soluble forms.
Phosphate solubilization takes place through various microbial processes/mechanisms, including organic acid production and proton extrusion. A wide range of microbial P solubilization mechanisms exist in nature, and much of the global cycling of insoluble organic and inorganic soil phosphates is attributed to bacteria and fungi. Phosphorus solubilization is carried out by a large number of saprophytic bacteria and fungi acting on sparingly soluble soil phosphates. Among different microbes, bacterial species from genera芽孢杆菌,假单胞菌,and根瘤菌, fungal species from genera青霉and曲霉, actinomycetes, and arbuscular mycorrhizae are popular phosphate solubilizing microbes inhabiting the soil.
磷酸盐溶解的微生物是分离出来的,并在称为Pikovaskaya(PVK)培养基的培养基上进行了表征。该培养基包含不溶性三氯磷酸盐(TCP)/羟基磷灰石作为唯一的P来源。磷酸盐溶解的微生物在其菌落周围产生清晰的光环。磷酸盐溶解微生物在土壤中溶解不溶性磷酸盐的能力是为了增强农业增强生物肥料的良好属性。因此,它们在农艺实践中被广泛应用为生物量化剂,因为它们在更环保,具有成本效益和可持续性的方式中起着重要作用,而不是化肥。
什么是磷酸盐动员?
磷酸盐动员微生物是参与土壤中磷的微生物。大多数磷酸盐动员微生物是磷酸盐溶解的微生物。他们从土壤中的不溶性和固定形式的磷释放磷。结果,土壤P的可用性增加,植物能够以可持续的方式吸收磷。
磷酸盐通过更改pH和产生螯合物质动员磷动员磷。磷酸盐溶解和磷酸盐动员的术语可互换用于指磷酸盐溶解微生物。磷酸盐动员微生物参与土壤的转化过程。

摘要 - 磷酸盐溶解与磷酸盐动员
磷是植物所需的主要大量营养素之一。微生物是磷循环的组成部分。大多数土壤磷都以不溶性磷酸盐的形式存在。磷酸盐动员微生物有助于动员土壤中不溶性和固定形式的磷。磷酸盐溶解的微生物溶解不溶的无机磷酸盐将磷酸盐溶解和动员微生物都非常重要,因为农业中的生物含水剂会增加植物的土壤P的可用性。因此,这总结了磷酸盐溶解和磷酸盐动员之间的差异。
