Definition of fungus control

"Antibacterial" in antimicrobial processed products that are currently on sale is "a state that suppresses the growth of bacteria (including fungi) on the surface of products." It is a function different from "sterilization" which kills microorganisms and "bacteria removal" which removes microorganisms.
Below is a summary of differences in antibacterial, sterilization, sterilization, disinfection, and eradication.





Condition that suppresses bacterial growth on the surface of products 1) ≒ bacteria 2)


Kill or remove all microorganisms in the substance 3)


Kill some or most microorganisms in the substance 4)


A treatment method used to reduce the number of surviving microorganisms, not necessarily to kill or remove all microorganisms 5)

Removing bacteria

Reduce the effective amount of the number of bacteria (viable count) that can grow from the object.  However, fungi such as mold and yeast are not included 6)

General "antibacterial mechanism" hypothesis

Antibacterial agents have different effects on microorganisms depending on their chemical structure, but various theories have been proposed regarding the antibacterial mechanism. A typical one is any combination of the following.


Antibacterial substances. . .

1. Adsorbs on the surface of microorganisms and inhibits various functions of cell membranes

2. Destroy cell membranes and cell walls to make holes and leak intracellular material (see below)

3. Invade into cells and directly organize intracellular substances or inhibit their function

4). Inhibits respiration by destabilizing the respiratory enzymes that are retained in the cell membrane

5). Inhibits cellular DNA and RNA gene synthesis or inhibits transcriptase

(Inhibits the synthesis of various proteins in cells)

6). Other effects such as sterilization by hydroxy radicals created by photoexcitation

The above figure is an example of the mechanism of a general antibacterial agent. Antibacterial substances have an antibacterial effect by destroying cell membranes and cell walls, making holes and killing microorganisms.
