      Currently, 90% of the bacterial fertilizers on the market will add this Bacillus subtilis! Because it has the following 8 benefits.目前市场上90%的细菌肥料都会添加这种枯草芽孢杆菌!因为它有以下8个好处。

1. Antibiotic effects. 1. 抗生素的影响。

      Antibiotic effect refers to the inhibitory effect of antibiotics on the growth and metabolism of pathogenic microorganisms by producing metabolites at low concentrations, thereby affecting their survival and activity. Over the past half century, various effective antibacterial substances have been isolated and purified from the metabolites of different strains of Bacillus subtilis.抗生素效应是指抗生素通过产生低浓度的代谢物来抑制病原微生物的生长和代谢，从而影响病原微生物的生存和活性。半个多世纪以来，人们从枯草芽孢杆菌不同菌株的代谢产物中分离纯化出多种有效的抗菌物质。

2. Bacteriolysis. 2. 溶菌作用。

      The bacteriolytic effect of Bacillus subtilis is mainly manifested by adsorbing on the mycelium of pathogenic bacteria, growing with the growth of the mycelium, and then producing bacteriolytic substances that cause protoplast leakage and mycelium breakage; Alternatively, the production of antibacterial substances can inhibit spore germination by dissolving the cell wall or membrane of pathogenic spores, leading to perforation and deformity of the cell wall.枯草芽孢杆菌的溶菌作用主要表现为吸附在致病菌的菌丝上，随着菌丝的生长而生长，然后产生溶菌物质，造成原生质体渗漏和菌丝断裂;或者，抗菌物质的产生可以通过溶解致病孢子的细胞壁或膜来抑制孢子的萌发，导致细胞壁穿孔和变形。

3. Induce plant resistance and promote plant growth.3. 诱导植物抗性，促进植物生长。

     Among them, Bacillus subtilis has the strongest stress resistance, the most functions, the widest adaptability, and the most stable effect. Bacillus subtilis can produce substances similar to cytokinins and plant growth hormones, promoting plant growth and resisting the invasion of pathogens.其中枯草芽孢杆菌抗逆性最强，功能最多，适应性最广，效果最稳定。枯草芽孢杆菌能产生类似细胞分裂素和植物生长激素的物质，促进植物生长，抵抗病原体的侵袭。

4. Protect the environment.4. 保护环境。

     Bacillus subtilis is widely used in biological fertilizers. When used for crops or soil, it can colonize in the rhizosphere or body of crops and have a specific fertilizer effect. At present, microbial fertilizers are used to enhance soil fertility, improve fertilizer utilization efficiency, inhibit the absorption of nitrate nitrogen, heavy metals, and pesticides by crops, purify and repair soil, reduce crop diseases, and promote the maturation and utilization of crop straw and urban waste. The improvement of crop product quality and food safety has played an irreplaceable role.枯草芽孢杆菌在生物肥料中应用广泛。当用于作物或土壤时，它可以在根际或作物体中定植，并具有特定的肥效。目前，微生物肥料用于增强土壤肥力，提高肥料利用效率，抑制作物对硝态氮、重金属和农药的吸收，净化修复土壤，减少作物病害，促进作物秸秆和城市废弃物的成熟利用。对提高农作物产品质量和食品安全起到了不可替代的作用。

5. The adsorption and biodegradation functions of Bacillus subtilis on phenanthrene and benzopyrene in soil.5. 枯草芽孢杆菌对土壤中菲和苯并芘的吸附和生物降解作用。

     The water environment connected to the soil is called the soil water environment system, which contains a large number of inherent soil microorganisms and biofilms on the surface. Because biofilms form an isolation layer, organic pollutants must first reach and pass through this isolation layer before coming into contact with the solid substrate supporting the biofilm. This strongly changes the adsorption behavior of mineral particles or substrates, and has a significant impact on adsorption.与土壤相连接的水环境称为土壤水环境系统，土壤水环境系统含有大量固有的土壤微生物和表面的生物膜。由于生物膜形成了一个隔离层，有机污染物必须首先到达并通过这个隔离层，然后才能与支撑生物膜的固体基质接触。这强烈地改变了矿物颗粒或底物的吸附行为，对吸附有显著的影响。

     Research has shown that using Bacillus subtilis as inoculum microorganisms, both phenanthrene and benzopyrene can be adsorbed or biodegraded. When the liquid phase PAHs concentration reaches equilibrium after 48 hours, the microorganisms eliminate 98% of phenanthrene and 85% of benzopyrene. The adsorption isotherms of the inoculated samples after 48 hours are all linear, which can well fit the linear equation.研究表明，以枯草芽孢杆菌作为接种菌，对菲和苯并芘均可吸附或生物降解。当液相多环芳烃浓度在48小时后达到平衡时，微生物可去除98%的菲和85%的苯并芘。接种样品在48h后的吸附等温线均为线性，可以很好地拟合线性方程。

6. The effect of Bacillus subtilis on the respiratory intensity of soil microorganisms.6. 枯草芽孢杆菌对土壤微生物呼吸强度的影响。

     As one of the indicators of soil biological activity, soil respiration intensity can reflect the transformation and supply capacity of soil nutrients to a certain extent. The change and direction of its respiration rate also reflect the sensitivity and response mode of the ecosystem to stress. It is an important indicator for environmental safety assessment. When the soil is polluted by foreign pollutants, microorganisms may need more energy to maintain their survival, leading to varying degrees of response in the metabolic activity of soil microorganisms.土壤呼吸强度作为土壤生物活性的指标之一，可以在一定程度上反映土壤养分的转化和供给能力。其呼吸速率的变化和方向也反映了生态系统对胁迫的敏感性和响应方式。它是环境安全评价的重要指标。当土壤受到外来污染物污染时，微生物可能需要更多的能量来维持其生存，从而导致土壤微生物的代谢活动出现不同程度的响应。

7. The effect of Bacillus subtilis on soil urease activity.7. 枯草芽孢杆菌对土壤脲酶活性的影响。

    The application of soil enzymes as monitoring indicators to evaluate the ecotoxicological effects of pesticides has become one of the research hotspots in the field of environmental science. Urease belongs to a type of hydrolase that has been extensively studied in soil, and is the only enzyme that has a significant impact on the conversion and utilization of urea in soil.应用土壤酶作为监测指标评价农药的生态毒理学效应已成为环境科学领域的研究热点之一。脲酶是一种在土壤中被广泛研究的水解酶，是唯一一种对土壤中尿素的转化和利用有重要影响的酶。

    After urea is applied to the soil, it rapidly decomposes into carbon dioxide and ammonia under the catalytic action of urease. Therefore, the decrease in soil urease activity not only slows down urea hydrolysis, but also allows more of its hydrolysis products to be adsorbed by the soil, effectively reducing the volatilization loss of urea hydrolysis product ammonia, and may correspondingly reduce the potential for NH nitrification of hydrolysis products.尿素施于土壤后，在脲酶的催化作用下迅速分解为二氧化碳和氨。因此，土壤脲酶活性的降低，不仅减缓了尿素水解，而且使其水解产物更多地被土壤吸附，有效降低了尿素水解产物氨的挥发损失，也可能相应降低水解产物NH硝化的潜力。

8. Improvement of saline alkali land by Bacillus subtilis.8. 枯草芽孢杆菌改良盐碱地。

     The hazards of salt accumulation in soil include soil structure viscosity, poor aeration, high bulk density, rising soil temperature, poor activity of aerobic microorganisms, slow nutrient release, low permeability coefficient, and strong capillary action, which further exacerbate surface soil salinization and cause soil cold, hard, and flat phenomena. Generally speaking, when the accumulation of water-soluble salts in the surface or sub surface of soil exceeds 0.1%, or the alkalinity of the soil alkaline layer exceeds 5%, it belongs to saline soil.土壤中盐分积累的危害包括土壤结构黏性、通气性差、容重高、土壤温度升高、好氧微生物活性差、养分释放缓慢、渗透系数低、毛细作用强等，进一步加剧土壤表层盐碱化，造成土壤冷、硬、平现象。一般来说，当土壤表层或亚表层水溶性盐的积累量超过0.1%，或土壤碱性层的碱度超过5%时，属于盐渍土。
