Introduction:

Bacillus subtilis, is also called as hay bacillus or grass bacillus it is a gram +ve bacteria, rod shaped , found in the soil, and found in the gastrointestinal tract of the human. It survives in hard environment because it has a hard endospore allowing them to sustain them in extreme conditions.

Uses of Bacillus subtilis 

Probiotic supplements It is commonly used as probiotic supplements because of the gut health enhancing properties and it boosts the immune system by competing with harmful bacteria found in the gut

Production of industrial enzyme It is used to produce various type of enzymes like proteases, amylases and lipases. This type of enzymes are important in food processing industries, detergent and textile industries.

Used as Bio control agent To control pathogens in agriculture field it is used as a biocontrol agent as an biological method of management, it is also used to produce antibiotics and metabolites which is used to reduce the growth of bacteria and fungi.

Applications in agriculture

Used in disease management It plays a major role in managing of diseases in plants. It act in controlling various things like pathogens, fungi, bacteria and nematode as an biocontrol agent. It reduce the ability of the pathogens by colonizing and make it inability to cause damage.

Promotion of plant growth It also promotes plant growth, by it produce phytohormones like gibberellin, cytokinin, and auxin which can help in improving the development of root. It also has the properties like solubilizing phosphate and make it absorbed for plants

Improvement of Soil health It decomposes the organic matter and recycle the nutrients that improves the soil organisms to improve. The present in microbiome in soil diverse the microbial community which is very Important for sustainable agriculture, it breaks down into simpler form that plants absorb.

Used as Biofertilizers The eco friendly and it is seen as the alternative for the chemical fertilizers the Bacillus subtilis is gaining popularity now that it enhances the fertility of the soil by reducing the synthetic inputs it can be more sustainable farming in future for a unharmful way to safe the environment

Conclusion

Bacillus subtilis is a unique and a beneficial micro organism plays an important role in agriculture. It’s ability to improve soil health and controlling diseases of plants makes them as a valuable to farmers, they found it very useful. In sustainable agriculture the role of the Bacillus subtilis is vital and it is important in making environment healthy and ensuring food security in farming
