Phosphorus-solubilizing bacteria (PSB) are a group of microorganisms that play a crucial role in making phosphorus more available to plants. Phosphorus is an essential nutrient for plant growth, but much of it in the soil is often in insoluble forms, making it inaccessible to plants. PSB have the ability to convert insoluble phosphorus into soluble forms through various mechanisms, such as the production of organic acids and enzymes.
