Ect-S, as a new type of biological protective agent, has attracted extensive attention in the field of agricultural microbial preparations because of its unique protective mechanism. It can not only protect plant cells from the impact of stress, but also significantly improve the activity and stability of microbial agents, known as "microbial protection God". In this paper, the mechanism of action of Ect-S and its application in maintaining the activity of bacteriotics will be introduced in detail.

　　Mechanism of action of Ect-S

　　Stable cell membrane structure: Ect-S can interact with the cell membrane of the microbial agent, enhance the stability of the cell membrane, and reduce the damage caused by changes in the external environment. This helps maintain the integrity of the membrane of the bactericide and ensures that the bactericide remains active under adverse conditions.

　　Protect protein structure: Ect-S helps maintain the correct folded state of the protein by interacting with the proteins in the bactericide to avoid protein denateration. This is essential for maintaining the bioactivity of the bactericide, as proteins are the basis for performing multiple biological functions.

　　Formation of hydration layer: Ect-S is able to associate more water molecules to form a hydration layer around the bactericide. This hydration layer not only provides a stable microenvironment for the bactericide, but also prevents the bactericide from losing its activity due to drying or temperature fluctuations.

　　Application of Ect-S in the protection of bacteriotics

　　Improve the antimicrobial resistance: In the harsh environment such as drought, high temperature, salt and alkali, Ect-S can help the antimicrobial resistance to these adverse factors, thereby improving the survival rate and antimicrobial resistance.

　　Prolonging the shelf life of bactericide: Ect-S can effectively delay the inactivation process of bactericide and extend the shelf life of bactericide. This is important for the storage and transportation of bactericide products, ensuring that the bactericide maintains a high biological activity when used.

　　Ensure the efficacy of the bactericide: By stabilizing the membrane and protein structure of the bactericide, Ect-S helps to ensure the effectiveness of the bactericide. This means that in practical applications, bactericides can work more efficiently, such as promoting plant growth and increasing crop yields.

　　Ect-S, as a highly effective bioprotective agent, has shown outstanding ability in protecting microbial inoculants. By stabilizing the cell membrane, protecting the protein structure, and forming a hydration layer, Ect-S not only enhances the resistance and shelf life of the bactericide, but also ensures its effectiveness. In the future, with the further exploration of its mechanism of action and the continuous progress of application technology, Ect-S is expected to play a greater role in the field of agricultural microbial preparations and contribute to the sustainable development of modern agriculture.
