Disinfectant Mechanism Of Action

Disinfectants are also commonly referred to as chemical disinfectants. Disinfectant used to kill the pathogen on the media, to achieve harmless requirements, the pathogenic microorganisms eliminated from the human body, cut off the transmission of infectious diseases, to control the purpose of infectious diseases. Disinfectant in accordance with the level of its role can be divided into sterilizers, highly effective disinfectant, in the disinfectant, inefficient disinfectant.

Disinfectant mechanism of action

(A) the role of the cell wall Many low concentrations of disinfectant microbial cell wall can be dissolved to achieve the purpose of sterilization; such as phenolic disinfectant can dissolve the breeding period of E. coli, because the bacteria at this time the membrane fragile and low phospholipid content , And easy to be destroyed; and glutaraldehyde can be cross-linked with the cell wall lipoprotein, wall wall of the esterification of ester residues in the wall to form side chains, thus blocking the cell wall, hinder the absorption of nutrients and waste of microorganisms The

(B) the role of the cell membrane studies have shown that: to change the permeability of the cell membrane, so that the contents of the membrane leakage. Surfactants and other disinfectants can penetrate a large number of microcellular cell walls into the cell, and membrane and phospholipid-protein complex reaction, destruction of local or the entire organizational structure so that low molecular weight (such as nucleotides, Amino acids) escape from the cytoplasm, and even induce autolysis caused by cell wall dissolution.

(C) the effect of disinfectants on intracellular components of the cytoplasmic protein and enzyme irreversible degeneration, coagulation, resulting in structural proteins and functional proteins are severely damaged; at the same time involved in a variety of physiological metabolic activity of the enzyme structure and function is destroyed , So that bacteria are in a state of paralysis and rapid death. Affect the biosynthesis and function of nucleic acids. Many disinfectants can react with nucleotides, such as purine and pyrimidine ring amino groups are often the target of disinfectant, causing a series of adverse consequences. Disinfectants can also destroy the structure and function of ribosomes, hinder the synthesis of protein.
