Classification and mechanism of fungicides
Different agents have different sterilization mechanism, which can realize the effect of sterilization, but also avoid the re-pollution of water quality, fully maintain the water quality, to bring benefits to the enterprise. The following is a general information about the classification and action of fungicides.
Nonoxidizing fungicides are toxic agents applied to a specific part of a microorganism, and then damage the cells or life parts of the microorganism to achieve the purpose of sterilization?
Containing bromine: dibromocyanopropanamide, etc., after joining water, immediately release bromine atom, use bromine atom to attack electrophilic material containing sulfur amino acid, so that amino acid protein inactivation. This type of fungicide kills bacteria, molds, yeasts, and algae very quickly. Our K-Bio DB20 is a formula product developed based on this active substance. The product has good stability and is welcomed by customers in different industries。
Chlorophenols: such as dichlorophenol, pentachlorophenol; Sterilization MECHANISM: Chlorophenols can be adsorbed on the microbial cell wall, and then dispersed into the cell structure, the formation of colloidal solution in the cell, so that protein deposition, and then damage the protein to kill bacteria.
Quaternary ammonium salts: quaternary ammonium salts belong to cationic surfactants. Because their hydrophobic groups contain water-soluble groups, the dispersion of quaternary amine salts in water is improved, the surface activity is increased, the adsorption of fungicides in bacteria is strengthened, and the respiration and glycolysis of bacteria are blocked. Quaternary amine salts can also denature proteins, allowing chlorine and phosphorus compounds to leak out of cells and cause cell death.
Quaternary phosphine salts: mainly rely on the active part of the heterocyclic ring, such as N, H, O and the DNA base in the bacteria protein to form oxygen, adsorption on the cell, and then damage the structure of the DNA in the cell, resulting in the loss of DNA reproduction ability, and then make the cell death.
Heterocyclic compounds: organic sulfur compounds, organic amine compounds: mainly rely on the active part of the heterocyclic ring, such as N, H, O and the DNA base in the bacteria protein to form oxygen, adsorption on the cell, and then damage the structure of the DNA in the cell, leading to the loss of DNA reproduction ability, and then make the cell death
Organic ALDEHYDES, SUCH AS GLUTARALDEHYDE, FINISHED product concentration 50% or 25% : STERILizing effect is the aldehyde group, the aldehyde group of oxygen with a negative charge, carbon with a positive charge. The positively charged carbon reacts with the amino group NH: and the sulfur group SH: of the bacterial protein, which then damages the bacterial protein and leads to the death of the bacteria.
