Bacillus Licheniformis Application in Agricultural Planting

Bacillus licheniformis is one of the potential strains of Bacillus. It is a gram-positive rod-shaped bacteria that can produce endophytic spores, has a strong heat resistance and stress resistance, and is ubiquitous in soil and plant surfaces. It is a common endophytic bacteria in plants and is non-toxic and harmless to humans and animals.

In recent years, the research and application of Bacillus licheniformis have become more and more in-depth. Next, the application of Bacillus licheniformis in agricultural cultivation will be described. 

Bacillus Licheniformis application

1. Effect on Crop Growth

Can produce a variety of active substances to stimulate crop growth. Regulating life activities, Bacillus licheniformis can promote the growth of crop roots, increase fibrous roots, and strengthen roots.

2. Control of Plant Diseases

The metabolites of Bacillus licheniformis contain a variety of effective protein antibacterial substances, such as chitinase, antibacterial proteins, polypeptides, and phenylacetic acid. In our experiments on tomatoes, we found that Bacillus licheniformis has a strong colonization ability, competes with Botrytis cinerea for nutrition and space, and has a good inhibitory effect on Botrytis cinerea. On rice, Bacillus licheniformis has a strong inhibitory ability to the rice blast fungus, and the field control effect reaches more than 50%.

Antibacterial substances inhibit plant pathogenic bacteria by acting on the cell wall and cell membrane of pathogenic bacteria; interacting with membrane-related receptor proteins; acting on the energy metabolism system; improving plant disease resistance.

3. Effect on Soil Microbial Community

After being applied to the soil, it rapidly multiplies and multiplies, produces a large number of beneficial bacteria, inhibits the growth of harmful bacteria, and can coexist with beneficial bacteria for a long time, which is the balance of soil microorganisms.

4. Pesticide Degradation

It has a certain degradation effect on fenvalerate, cypermethrin, and fenvalerate, with degradation rates of 53%, 41%, and 60%.

5. Improve Fertilizer Efficiency

Bacillus licheniformis can produce a large number of plant endogenous enzymes in the metabolic process, which can significantly improve the mutual coordination and absorption rate of beneficial factors such as nitrogen, phosphorus, potassium and middle and trace elements. Under the same conditions, the yield can be increased by 15% to 30 %.
