Indogulf BioAg is a Manufacturer & Global Exporter of Phosphorous solubilising, Bacillus Megaterium, Aspergillus, Pseudomonas & other Bacterias. Contact us @ +1 437 774 3831 < Microbial Species Phosphorous Solubilizing Bacteria Phosphorous Solubilizing Bacteria convert insoluble phosphates into soluble forms that plants can absorb, improving phosphorus availability and promoting stronger root development. Product Enquiry What Why How FAQ What it is Phosphorus solubilizing bacteria (PSB) are a group of beneficial microorganisms that enhance the availability of phosphorus in the soil. Phosphorus is a crucial nutrient for plants, playing a key role in energy transfer, photosynthesis, and nutrient movement within the plant. However, much of the phosphorus in soil exists in insoluble forms that plants cannot absorb. PSB convert these insoluble forms into soluble phosphorus that plants can utilize. Why is it important Phosphorus is essential for plant growth, yet it is often a limiting nutrient in many soils due to its low solubility. The importance of phosphorus solubilizing bacteria includes: Enhanced Nutrient Availability : PSB increase the availability of phosphorus, promoting healthier and more robust plant growth. Improved Soil Fertility : By converting insoluble phosphorus compounds into forms accessible to plants, PSB contribute to overall soil fertility and ecosystem health. Sustainable Agriculture : Utilizing PSB can r educe the dependence on chemical phosphorus fertilizers , leading to more environmentally friendly and sustainable farming practices. How it works Phosphorus solubilizing bacteria employ several mechanisms to convert insoluble phosphorus into soluble forms: Organic Acid Production : PSB secrete organic acids such as citric acid, gluconic acid, and oxalic acid. These acids lower the pH around the bacteria, dissolving insoluble phosphate compounds and releasing soluble phosphorus ions that plants can absorb. Enzymatic Activity : Some PSB produce enzymes like phosphatases that break down organic phosphorus compounds into inorganic forms, making phosphorus available to plants. Ion Exchange Reactions : PSB can exchange ions in the soil , such as hydrogen ions (H+), with phosphate ions (PO4^3-), effectively mobilizing phosphorus from soil particles into the soil solution. By employing these mechanisms, phosphorus solubilizing bacteria play a vital role in enhancing phosphorus availability in the soil, supporting plant nutrition, and contributing to sustainable agricultural practices. FAQ What are examples of phosphate-solubilizing bacteria? Phosphate-solubilizing bacteria (PSB) represent a diverse group of microorganisms distributed across multiple bacterial genera. The most commonly isolated and commercially utilized PSB include: Primary PSB Genera Bacillus Species: Bacillus megaterium – One of the most efficient and widely used PSB, known for high phosphate solubilization rates and production of organic acids and phosphatase enzymes Bacillus firmus – Enhances phosphorus availability and promotes root growth Bacillus polymyxa – Combines phosphate solubilization with nitrogen fixation capability Bacillus subtilis – Effective phosphate solubilizer with biofilm formation ability Bacillus licheniformis – Produces multiple organic acids for phosphate dissolution Pseudomonas Species: Pseudomonas fluorescens – Widely researched PGPR producing gluconic acid and multiple plant growth-promoting compounds; increases crop yields in various crops Pseudomonas putida – Produces indole-3-acetic acid (IAA) promoting root architecture and contains 195.42 mg/mL soluble phosphorus production capacity Pseudomonas striata – Improves soil health and plant drought tolerance Pseudomonas aeruginosa – Enhanced plant growth parameters under various fertilization levels Various Pseudomonas isolates (PsT-04c, PsT-94s, PsT-116, PsT-124, PsT-130) – Isolated from tomato rhizosphere with solubilization indices (SI) ≥2 Other Important PSB Genera Arthrobacter Species: Arthrobacter sp.
