Phosphorus is one of the main macronutrients for plant development. Despite its large deposits in soils, it is scarcely available for plants. Phosphate-solubilizing bacteria, belonging to the group of plant growth-promoting rhizobacteria (PGPR), are capable of mobilizing deposits of insoluble phosphates in the soil. The use of PGPR as inoculants provides an environmentally sustainable approach to increase crop production. The effectiveness of inoculants depends on their proper production, formulation and storage in order to ensure the application of the required number of viable microbial cells. In order to develop inexpensive technology, low-cost compounds for biomass production and protection should be used. After the biomass production process, the product should be formulated in a liquid or a solid form, taking into account required storage time, use of protectors/carriers, storage conditions (temperature, humidity, etc.), ease of application and maintenance of beneficial effects on crops. Careful determination of these optimal conditions would ensure a low-cost efficient inoculant that would promote the growth and yield of various crops.

磷是植物发育的主要主要营养素之一。尽管其在土壤中有大量沉积物，但几乎无法用于植物。促磷酸盐的细菌属于促进植物生长的根际细菌（PGPR）类别，能够动员土壤中不溶性磷酸盐的沉积。PGPR作为接种剂的使用为提高作物产量提供了一种环境可持续的方法。接种剂的有效性取决于其适当的生产，配制和储存，以确保应用所需数量的活菌细胞。为了开发廉价的技术，应该使用用于生物质生产和保护的低成本化合物。在生物质生产过程之后，应将产品制成液体或固体形式，考虑到所需的储存时间，保护剂/载体的使用，储存条件（温度，湿度等），易于施用和对作物有益的影响。仔细确定这些最佳条件将确保使用低成本高效的孕育剂，以促进各种作物的生长和单产。
