STUDY ON DISINFECTION EFFICACY OF A COMPOUND CHINESE HERBS DISINFECTANT AND ITS GERMICIDAL MECHANISM

Objective To study the disinfection efficacy of a compound Chinese herbs disinfectant and its germicidal mechanism. Methods Field disinfection test and molecular biological technique were used to research the disinfection effect on seafood and mechanism of disinfectant. Results The average killing rate of natural bacteria in seafood exposed to the components of disinfectant for 15 minutes was above 90%; while the average killing rate of manual bacteria in dinner set was above 99%. After exposure to the components of disinfectant for 15 minutes,both bacteria showed leakage of protein and the amount of leakage added with increasing concentration. Conclusion The compound Chinese herbs disinfectant has good bactericidal efficacy against bacteria in seafood and dinner set. The disinfectant can enhance permeability of cell wall and cell membrane to show leakage of protein,and ultimately results in the death of bacteria.
