Bacillus amyloliquefaciens

It is well known that Bacillus amyloliquefaciens belongs to a type of bacterial strain, which has powerful effects such as antagonizing boats, releasing antibacterial substances, improving soil, and reducing pesticide residues. It is precisely because of this that Bacillus amyloliquefaciens has played a widespread role in scientific research, experimental testing and other related fields. So what other mechanisms of action does Bacillus amyloliquefaciens have?

Bacillus amyloliquefaciens is a Gram-positive bacillus that can contaminate hospitals' 75% alcohol disinfectant, moisture-damaged houses, and food, causing infections in special populations with low immunity, such as newborns and infants, and housing contamination health syndrome.

【Mechanism of action】

The mechanism of action of Bacillus amyloliquefaciens mainly includes secretion of antimicrobial substances, antagonism, competition for nutrients and space, induction of host resistance and promotion of plant growth.

1. Secretion of antibacterial substances: Produces low molecular weight antibiotics and active substances such as antibacterial proteins or peptides to inhibit plant diseases

It can also promote plant growth as a rhizobacterial. It is synthesized by non-ribosomal pathway, has small molecular weight, good thermal stability, and contains D-amino

Lipopeptide antibiotics, which are resistant to protease hydrolysis and organic solvents, play a major role in the inhibition of plant pathogenic bacteria, fungi, viruses and nematodes in biological control applications.

2. Antagonism: Microorganisms produce antimicrobial substances through assimilation to inhibit the growth or development of harmful pathogens or directly

Kill pathogens. Directly interact with pathogens. In addition to producing secondary metabolites such as antibiotics, it also produces a series of extracellular hydrolases that play an important role in inhibiting pathogens.

This prevents pathogens from obtaining suitable nutrition and space conditions and from reproducing, thus inhibiting the occurrence of diseases.

4. Induce host resistance: When plant tissues suffer mechanical damage or infection by pathogens, a series of physiological and biochemical reactions will spontaneously occur in the body to resist the damage caused by these factors to itself.

Bacillus amyloliquefaciens can induce this natural defense mechanism in plants.

5. Promote plant growth: Bacillus amyloliquefaciens can produce gibberellins, indoleacetic acid, cytokinins and other bioactive substances.

It contains physiologically active substances and amino acids, which promote the growth of plant roots and plants, enhance plant disease resistance, and thus indirectly reduce the occurrence of diseases.

1. Broad-spectrum and high efficiency in disease resistance and antibacterial inhibition: Experiments have shown that this product has significant preventive effects on soil-borne diseases such as tomato leaf mold, early blight, gray mold, cucumber wilt, anthracnose, melon wilt, pepper late blight, wheat, rice sheath blight, corn leaf spot, and soybean root rot.

2. Resistance to stress, anti-aging and growth promotion: Bacillus amyloliquefaciens can induce crops to produce superoxide dismutase (SOD), polyphenol oxidase (PPO), peroxidase (POD), etc., to improve crop resistance to stress; it can induce plants to quickly secrete endogenous auxin, promote rapid rooting of crops, improve root development ability, and promote healthy growth of plants.

3. Improve soil and increase fertility: Bacillus amyloliquefaciens can improve the rhizosphere microecology of crops, activate potential nutrients such as insoluble phosphorus and potassium in the soil, improve soil, loosen soil compaction, curb soil degradation, and improve soil fertility.

4. Reduce pesticide residues and increase yields: Bacillus amyloliquefaciens can degrade residual pesticides in the soil and fruits, reduce nitrite content, increase the vitamin and sugar content of fruits and vegetables, improve the quality of agricultural products, increase crop yields, and facilitate storage and transportation. Improve and prolong fertilizer effectiveness and reduce the use of chemical fertilizers.
