Mechanism of anti-mold agent
Anti-mildew agent refers to an additive to prevent the growth of mold. Food, fruit, feed, cosmetics, coatings, adhesives, leather, aquatic products, plastics, etc., are prone to mold contamination during use and storage, making the finished products deteriorate. In order to prevent the growth of mold, it is necessary to add anti-mold agents to the product. What is the mechanism of anti-mold agent? The following:
The moulds of corrosion coatings and coating films belong to fungi, including Aspergillus sari, Aspergillus aflatus, Aspergillus Niger, Aspergillus albicans, Aspergillus nidulus, Penicillium purpurea, Penicillium diffusum, Penicillium dermoides, trichoderma, cephalosporus, cladomyces spore, cladomyces transversarii, Staphylosporus staphylospore, etc.
Molds are a vast group of microorganisms that are found almost everywhere in soil, water, plant and animal life, or air. Mold depends on absorbing nutrients from other objects, to survive in a parasitic or saprophytic way, can secrete a variety of enzymes, break down organic matter into easily ingested nutrients. As long as there is very little nutrition, under the appropriate temperature (26 ~ 32 ° C) and relative humidity (>85%), mold can grow and reproduce. The killing effect of anti-mildew agent on mold is to enter the cell through the membrane of the spores and hinder the spore germination or kill the spores.
The toxic action of anti-mildew agent on mold includes the following ways: eliminate or inhibit the activity of various metabolic enzymes in mold cells; React with amino or sulfhydryl groups of enzyme proteins to inhibit or destroy their functions; Inhibit RNA synthesis during spore germination, thus preventing spore germination; Accelerate the promotion of phosphoric acid oxidation-reduction system to destroy cell function; Destroy the energy release system in mold cells; Inhibition of electron transfer system and transaminase system.
