How Does Bacillus megaterium Support Plant Growth and Enhance Soil Fertility?

Technical Introduction

Bacillus megaterium is a large, Gram-positive, spore-forming bacterium widely recognized for its role as a plant growth-promoting rhizobacterium (PGPR).
It produces various enzymes, vitamins, and phytohormones that facilitate nutrient availability and stimulate plant development.
B. megaterium is also utilized in biotechnological applications for enzyme production and bioremediation.

Applications

1. Agriculture and Horticulture

• Enhances nutrient solubilization, especially phosphorus, improving plant nutrient uptake.

• Produces growth-promoting substances such as indole-3-acetic acid (IAA) and vitamins.

• Suppresses soil-borne pathogens by producing antimicrobial compounds.

2. Environmental and Industrial Uses

• Produces enzymes like amylase and protease for industrial applications.

• Used in biodegradation and bioremediation processes due to its metabolic versatility.

Advantages

• Robust and Resilient: Forms spores, enabling survival under harsh conditions.

• Multi-Functional: Combines plant growth promotion with pathogen suppression.

• Safe and Eco-Friendly: Non-pathogenic and widely used in organic farming.

• Cost-Effective: Easily cultured and formulated for various applications.
