Bacillus Polymyxa 
Catalog Number A-1034
Description Bacillus polymyxa is a rod-shaped, Gram-positive bacterium that fixes nitrogen anaerobically. It measures 0.6 by 3.0 μm and forms pale colonies on agar. Reproduction involves the formation of ellipsoidal spores that cause the mother cell to swell noticeably. These endospores can germinate under favorable conditions. Spore germination can be influenced by factors such as heat activation and the presence of nutrients like fructose and L-alanine, while organic acids can impact the spores' heat resistance. In its vegetative state, P. polymyxa possesses peritrichous flagella that facilitate motility and swarming.

• Natural phosphorus solubilization enhances both plant and soil health.
• Promotes root expansion and plant growth by producing hormones such as cytokinins, auxins, ethylene, and gibberellins.
• Reduces pathogenic fungal activity by generating antibiotics and boosting rhizosphere immunity.
• Fixes nitrogen by converting atmospheric N₂ into ammonia (NH₃), which is usable by plants.
• Improves soil structure and porosity through organic compounds released by Bacillus polymyxa.
• Bacillus polymyxa is effective against taro soft rot, Chinese cabbage soft rot, pepper root rot, flower root rot, Polygonatum root rot, Adenophora root rot, tomato damping-off, tomato wilt, pepper blight, and other soil-borne diseases, providing effective control.
• Bacillus polymyxa is a versatile bacterium with several key functions:
• Metabolic Flexibility: It can perform aerobic respiration or switch to fermentation depending on oxygen availability. It utilizes various organic carbon sources and produces metabolites such as acetoin, lactate, and ethanol.
• Antibiotic Production: It synthesizes antibiotics and antifungal compounds, including polymyxin, paenibacillin, and fusaricidin.
• Disease Protection: It protects tomato seedlings from bacterial wilt caused by Ralstonia solanacearum by forming a biofilm around the roots, which prevents pathogen entry and colonization.
• Bioremediation: It uses exopolysaccharides for biofilm formation and can absorb cadmium (Cd²⁺) from aqueous solutions, aiding in environmental cleanup.
• Fermentation Organic Fertilizer with Microbial Powders:
• Use 100-200 grams per ton of fermentation organic fertilizer when cooperating with other microbial powders.
• Seedling Treatment:
• Mix 100 grams of Bacillus polymyxa with sufficient water and organic manure to create a slurry.
• Dip the seedlings in the slurry for 30 minutes before planting to ensure the bacteria attach to the roots.
• Soil Application:
• Mix 3-5 kg of Bacillus polymyxa with compost.
• Apply this mixture to 1 acre of soil.
• Drip Irrigation:
• Mix 3 kg of Bacillus polymyxa with the drip irrigation stream per acre.
