Sulphur is essential for high yield and is involved in the formation of proteins, vitamins, and enzymes. Sulphur oxidizers work to convert elemental sulphur into plant-available sulphate. All sulphur transformations are propelled by the soil microbial biomass. Through the oxidation process in the soil, they produce sulphate from elements or reduced forms of sulphur. Sulphur-solubilizing bacteria containing bio-fertilizer improves the microbial load of sulphur-solubilizing bacterial strains in the soil. Hence, it induces sulphur conversion in the soil and increases crop yield.

Mechanism of action of Sulphur Solubilizing Bacteria

Sulphur bacteria form a variety of mutualistic interactions depending on whether they interact with oxidised or reduced sulphur compounds. The bacterial strains produce active cells that grow, multiply, and mobilize the insoluble sulphur present in the soil. Hence, it ultimately increases and improves the uptake of sulphur and makes it readily available to the plant.

Benefits of Sulphur Solubilizing Bacteria

  • It helps in the chlorophyll formation that allows photosynthesis, by which plants produce starch, sugars, oils, fats, vitamins and other compounds.
  • Sulphur improves plant’s winter hardiness.
