Bacillus polymyxa is an anaerobic nitrogen-fixing Gram-positive bacterium that is rod-shaped, 0.6 by 3.0 μm in size, and produces pale colonies on agar. For reproduction it differentiates into ellipsoidal spores which distinctly swell the mother cell. The endospore can germinate when conditions are more suitable. Spore germination of P. polymyxa can be influenced by many factors including heat activation and nutrients such as fructose plus L-alanine . Organic acids can also affect the heat resistance of spores. When P. polymyxa isn’t in an endospore form, it has peritrichous flagella that aid in motility and swarming.

Natural Phosphorus solubilization improves both plant and soil health.
Increase root expansion and plant growth through producing hormones like cytokinins, auxins, ethylene and gibberellins.
Decrease the activity of pathogenic fungis by producing antibiotics and promoting immunity of rhizosphere.
Nitrogen fixing ability that can produce a form of nitrogen (ammonia NH3) that is usable by plants from atmospheric N2.
Improve soil fluctuation and porosity due to organic compounds released from bacillus polymyxa into the soil.
As a facultative anaerobe, it can perform aerobic respiration in the presence of oxygen or switch to fermentation when oxygen levels are low. It can use a variety of organic carbon sources such as glucose, sucrose, maltose, and arabinose and can produce a number of metabolites such as acetoin, lactate, and ethanol.
Baciullus polymyxa has the unique capability of synthesizing antibiotics/antifungal compounds. Three of these compounds include polymxin, paenibacillin , and fusaricidin.
Bacillus polymyxa has a unique capability of protecting tomato seedlings from bacterial wilt. Bacterial wilt is caused by Ralstonia solanacearum, a bacterium found in the soil that infects plants . R. solanacearum invades the plant through the roots and colonizes in the vascular bundles in the xylem vessels. As it grows and multiplies, it blocks the transportation of water and nutrients. P. polymyxa can prevent this bacterial wilt by colonizing and forming a biofilm around the roots of the tomato seedling, preventing the entrance of R. solanacearum.
Bacillus polymyxa also has potential uses in bioremediation. It surrounds itself with a compound called exopolysaccharide (or extracellular polymeric substance), which is important for biofilm formation and adhering to plant roots and soil particles. This exopolysaccharide can be used as an inexpensive and easily cultivable compound to remove cadmium (Cd2+) from aqueous solutions. This is achieved by the absorption of cadmium in the aqueous solution into the exopolysaccharide of Bacillus polymyxa.
Fermentation organic fertilizer: cooperate with other microbial powder are used together, adding amount of 100-200 g/ton
Seedling treatment : Mix 100 g. of Bacillus polymyxa with sufficient quantity of water and organic manure to form a slurry. The seedlings are dipped in this slurry for 30 minutes prior to planting so that the bacteria get attached to the roots.
Soil application : Mix 3-5 Kg/ acre of B acillus polymyxa with compost and apply to an acre of soil.
Drip Irrigation : Mix 3 Kg/ acre of Bacillus polymyxa in drip stream.
