Applied Biotech Industries manufactures Bacillus mucilaginosus (formerly Paenibacillus mucilaginosus) with advanced fermentation technology. Our fermentation process ensures maximum microbial viability and potency, resulting in a superior biostimulant product that helps to transform modern farming approaches.

This naturally-occurring biostimulant enhances soil fertility and crop growth. Its ability to solubilize potassium, phosphates, and silicates makes it an important tool for boosting plant nutrition while reducing reliance on synthetic fertilizers. Additionally, this plant growth-promoting rhizobacteria (PGPR) significantly enhances micronutrient availability, unlocking essential elements including Silicon, Calcium, Iron, Zinc, Manganese, Copper, Magnesium, Sulfur, and Molybdenum. This supports optimal plant metabolism and defense mechanisms against environmental stressors.  Key benefits include:

Potassium Solubilization

Bacillus mucilaginosus functions as a potassium-solubilizing bacterium, releasing plant-available potassium from minerals like feldspar and mica. This natural process enhances soil fertility, strengthens root systems, and builds plant resilience against drought and environmental stressors. Growers incorporating our B. mucilaginosus biofertilizer into their soil management practices reduce chemical fertilizer dependence while improving soil health and crop performance.

Phosphate and Silicate Solubilization

Bacillus mucilaginosus is a bacterial biostimulant that functions as both a phosphate-solubilizing and silicate-solubilizing microorganism, offering significant benefits for agricultural applications. By breaking down insoluble phosphate and silicate minerals in the soil, it makes these critical nutrients available to plants.

This soil probiotic releases phosphorus from bound soil minerals, promoting robust root development while simultaneously unlocking silicon from insoluble compounds, enhancing plant cell wall strength. Crops experience improved disease resistance, enhanced structural integrity, and greater stress tolerance through increased silicon uptake.

Enhanced Macro and Micronutrient Availability

The soil inoculant supports organic and sustainable farming by improving the transport and availability of many key nutrients, including:

Improved Soil Structure

This soil probiotic secretes polysaccharides that enhance soil aggregation, promoting better water retention, aeration, and microbial diversity, creating optimal conditions for plant growth.

Stress Tolerance (Drought & Heavy Metal Detoxification)

Bacillus mucilaginosus enhances plant resilience to drought stress by improving water retention and root development. It also helps detoxify heavy metals in contaminated soils by binding and transforming toxic elements, reducing their uptake by plants and promoting healthier growth in challenging environments.

Plant Growth Promotion

This plant growth-promoting rhizobacteria (PGPR) naturally stimulates plant growth by producing growth hormones (IAA, gibberellins), leading to stronger roots, faster development, and higher crop productivity.

Eco-Friendly and Sustainable
By enhancing nutrient cycling, B. mucilaginosus reduces reliance on chemical fertilizers, supporting sustainable and organic farming.

Bacillus mucilaginosus is a natural biofertilizer that enhances both macronutrient and micronutrient availability, leading to stronger, healthier, and more productive crops—all while promoting a sustainable farming future.
