Quenching Enzyme

Quenching enzyme is a special feed additive for aquatic animals produced by liquid submerged fermentation. This product contains active protein factors (AHLs), probiotics, antiviral factors, immune boosters and other biologically active substances, which can reduce and eliminate the pathogenicity of pathogenic bacteria and improve animal health. The quenching enzyme has good tolerance and stability, and can adapt to the digestive tract environment of aquatic animals and the special processing technology of aquatic feed.


Quorum sensing is widespread in nature. Quenching enzymes can hydrolyze the lactone ring of AHL to acylated homoserine, thereby interfering with bacterial quorum sensing, disrupting bacterial biofilm formation, regulating gene expression, and reducing exotoxin production. The application of quenching enzymes in feed can reduce the use of antibiotics in aquaculture, especially for diseases caused by Aeromonas hydrophila. A large number of aquatic animal experiments have shown that quenching enzymes can reduce freshwater aquaculture diseases, improve the survival rate and the economic benefits of aquaculture.
