Bacillus Megaterium

Bacillus megaterium for plant growth promotion and phosphate solubilization in agriculture

Bacillus megaterium is a gram-positive, spore-forming facultative bacterium, it’s widely used as plant growth promotion and organic soil enhancer in agriculture. It works as tree growth regulator that dissolve insoluble forms of phosphate into a more usable form for crops, leading to improved plant growth and development. Moreover, the plant fungicides also act as microbial soil amendments by producing antimicrobial compounds that suppress plant pathogenic bacteria and fungi. Where to buy the best soil inoculant, Novobac is a top manufacturer of bacteria and fungi for fermentation.

Antagonistic activity

Antagonistic activity of Bacillus MegateriumThe probiotic inhibits some pathogenic fungal diseases:

•   Coniellavitis (CV)

•   Gloeosporiumfructigrum (GF)

•   Botrytis cinerea (BC).

•   Diaportheeres (Pe).

•   Alternariaviticola (Av).

•   Fusariumoxysporum (Fo).

•   Aspergillusniger (An).

•   Pestalotiopsisclavispora (Pc).

•   Allorhizobiumvitis (Agv).

Mode of Action

The plant fungicide uses in agriculture as organic soil enhancer and plant growth promotion as following:

  • Phosphate solubilization: Dissolve insoluble forms of phosphate into a form that is more readily available to crops. This ability makes it uses biofertilizer to increase the availability of phosphate in soil and improve plant growth and development.
  • Plant growth promotion: Produce hormones, such as auxins and gibberellins, and enzymes, such as cellulases and proteases, that can improve plant growth and health.
  • Antagonistic activity against plant pathogens: Work as biocontrol agent and secrete antimicrobial compounds that can prevent the development of soil borne disease.
  • Ogranic soil enhancer: Improve soil structure and nutrient uptake, as the tree growth regulator can produce enzymes that can break down organic matter and increase the availability of nutrients in soil. This ability can help to improve soil fertility and support crops growth and development.



  • Improving fertilizer effectiveness and promoting absorption of phosphorus:
  • Increasing crop yield and improving crop quality:
  • Increases flowers and fruits, making fruit expand fast and taste good
  • Accelerates the growth of rhizobia and root system development
  • Biocontrol small plant root, yellowing, mosaic leaves, fallen leaves and flowers
  • Improves plant abiotic stress resistance to cold, drought, lodging, premature aging
  • Organic soil enhancer to improve soil fertility and support plant growth

Application Rate

  • Preparation: Mix it with water to create an inoculum solution.
  • Application: Apply the inoculum solution the earth around the base of the plants, either through watering or drenching.
  • Rate and frequency: Apply at rate of 3 kg the tree growth regulator per hectare if use alone, reapply after 4~8 weeks for season-long control, For sustainable agriculture, suggest to use it with other beneficial bacteria together.
  • Incubation: After application, incubate the soil for a few days to allow its endospore to colonize the soil and begin its beneficial activities.


What are the growth requirements for Bacillus megaterium in soil?

It is a versatile bacterium that can grow over a wide range of environmental conditions.. Optimal growth conditions typically occur at temperatures between 25-30°C. The minimum temperature is around 10°C, while the maximum temperature is around 40-45°C. It can also tolerate a wide range of pH conditions, with an optimal pH range of 7.0-7.5. It requires a variety of essential nutrients including carbon, nitrogen, sulfur, and phosphorus, as well as micronutrients such as iron and magnesium. At last, it is a facultative anaerobe, meaning that it can grow both in the presence and absence of oxygen. However, optimal growth typically occurs in the presence of atmospheric levels of oxygen.
