Microbial Solutions

1. 
   Special treatments including sporulation enhancement and microencapsulation are applied to the strain, giving it excellent stability in spore form. It is resistant to oxidation, compression, and high temperatures — capable of tolerating prolonged exposure to 140°F (60°C) and surviving at 248°F (120°C) for up to 20 minutes. It is also tolerant to acidic and alkaline conditions, remains active in acidic environments, and can withstand exposure to saliva and bile.

2. After entering the soil in spore form, Bacillus subtilis rapidly revives from dormancy and multiplies into a high-density dominant population within a short period. During this process, it consumes large amounts of oxygen in the soil and produces hydrogen peroxide and bacteriocins, establishing a microbial ecological balance, promoting the growth of beneficial anaerobic microorganisms, and suppressing harmful bacteria such as Escherichia coli and Salmonella.

3. During rapid proliferation, it produces a wide range of vitamins, organic acids, amino acids, and enzymes — including proteases (particularly alkaline protease), saccharifying enzymes, lipases, and amylases. These metabolites help decompose complex organic matter in the soil, promoting crop nutrient absorption and improving fertilizer use efficiency.

4. Safe and highly effective — no pesticide residues, no toxic side effects. It reduces reliance on antimicrobial pesticides and enhances plant immunity.

5. It demonstrates strong control efficacy against soil-borne diseases in fruit trees, melons, solanaceous crops, ginger, potato, Chinese yam, Panax notoginseng, and ginseng — including Fusarium wilt, Verticillium wilt, and root rot, as well as potato late blight and banana Panama disease (Fusarium wilt). The variant Bacillus methylotrophicus shows particularly strong preventive and curative effects against various soil-borne diseases, especially powdery mildew, root rot, and continuous-cropping disorders.

Bacillus amyloliquefaciens has strong disease-suppressive and antimicrobial activity. It can secrete more than a dozen antifungal substances, including lipopeptide antibiotics, antifungal proteins, and surfactin. These secretions interact physically and chemically with the lipid membranes of pathogens, disrupting membrane structure, causing leakage of intracellular contents, and ultimately leading to cell death. It can effectively inhibit plant pathogenic fungi and strongly suppress their activity, while also preventing sclerotial germination and mycelial growth in Sclerotinia species.

It can effectively suppress or alleviate a wide range of plant diseases, including wheat sharp eyespot, cotton wilt, cotton red rot, cotton Verticillium wilt, cucumber gray mold and blight, rapeseed and celery sclerotinia, rice blast, pepper wilt, yam root rot, apple anthracnose, ring rot, canker, brown spot, and many other crop diseases.

After application, concentrated Bacillus amyloliquefaciens powder can rapidly multiply and colonize the soil in large numbers, effectively excluding and blocking pathogenic microorganisms from infecting plants. At the same time, it secretes extracellular metabolites that directly kill or inhibit pathogen growth and reproduction. By attaching to pathogen cells, it can produce lytic substances that break down hyphae and cell walls, causing cell rupture, disintegration, perforation, and deformation. It can also induce the plant’s own disease-resistance potential, enhance plant immunity, stimulate the secretion of growth-promoting substances, and thereby support crop growth, yield improvement, and income increase.

In addition, Bacillus amyloliquefaciens shows a clear degradation effect on butachlor. The higher the initial concentration of butachlor, the higher the degradation rate and efficiency. Degradation is significantly better under alkaline conditions than under acidic conditions. The addition of humic acid not only adsorbs butachlor, but also promotes its microbial degradation and influences the resulting degradation products.

1．Improves the soil microecological environment.

2．Enhances thickening, lignification, and strengthening of plant tissue cell walls. It can also help form a cuticle–silica double layer on the epidermis, creating a barrier against pathogen invasion.

3．Converts insoluble phosphorus into available phosphorus, thereby improving phosphorus uptake efficiency in soil.

1. Metabolites produced by methylotrophic Bacillus—especially antifungal lipopeptide compounds—have strong antimicrobial activity against fungal plant diseases. They show remarkable control effects against cucumber and tomato gray mold, late blight, cotton yellow wilt and Fusarium wilt, and apple canker, and can also help control citrus canker, cucumber angular leaf spot, and rice bacterial leaf streak.

2. This strain can also produce aminopeptidase-like substances and act as a PGPR (plant growth-promoting rhizobacterium) to promote plant growth.

1．Competitive action

Endophytic Bacillus cereus competes with pathogens for colonization sites and nutrients, thereby suppressing plant diseases. Since its route of entry into the plant is similar to that of pathogens, it can occupy infection sites first and compete directly with pathogens for resources.

2．Antagonistic action

   Through metabolic activity, it produces antimicrobial substances that inhibit pathogen growth or kill pathogens directly. It can secrete a variety of antifungal and antibacterial antagonistic compounds, including novel cyclic antifungal polypeptides (APS), which have a broad antimicrobial spectrum and persistent inhibitory activity, significantly suppressing spore germination and hyphal growth of pathogenic fungi.

3．Induction of plant resistance

（1）It can induce physical resistance structures in host plants, leading to the accumulation of lignin and phenolic substances at attempted infection sites, thereby thickening cell walls and effectively blocking pathogen invasion.

（2）It can also trigger physiological and biochemical changes in host plants, including the accumulation of related proteins and the production of hydrolytic and oxidative enzymes such as chitinase, β-1,3-glucanase, and peroxidase, thus suppressing pathogen growth.

（3） Bacillus cereus can secrete superoxide dismutase (SOD), helping plants develop enhanced resistance to pathogens.

Biological Control of Diseases

1.Control of multiple fungal and bacterial diseases
This strain has been studied for its potential role in managing a range of fungal and bacterial diseases, including banana wilt, rice blast, cucumber wilt, pepper blight, root rot, damping-off, and other crop-related diseases.
