disinfection: kill or remove pathogenic microorganisms on the media, so that it can achieve harmless treatment.

sterilization: Treatment to kill or remove all microorganisms from a vector.

disinfectant: A preparation used to kill microorganisms on a vector so that they meet the requirements of disinfection or sterilization.

sterilant: A preparation that kills all microorganisms (including bacterial spores) to achieve sterilization requirements.

baxteriostasis: The process of inhibiting or inhibiting bacterial growth and reproduction and their activity by chemical or physical means.

antibacterial: bacteria living in the living environment as the object, the effect can last for years or decades; The bactericidal ability is below the sterilization level and above the static bacteria (bactericidal) level (stopping or reducing the activity of microorganisms, and inhibiting the propagation of microorganisms is called bactericidal or static bacteria); Can maintain the health of the living environment (microbiology) for a long time.

antisepsis: methods to prevent or inhibit the growth and reproduction of bacteria in vitro.

asepsis: The absence of live bacteria.

The above concept of "antibacterial" is very broad, can be popularily defined as: first control the activity and reproduction of microorganisms, create a clean environment, and gradually kill it a long-term bactericidal effect. Therefore, "antibacterial" contains a variety of definitions such as sterilization, bacteriostasis, disinfection and bacteriostasis, but it is not exactly what is commonly referred to as "sterilization" or "disinfection", and its antibacterial objects are bacteria, actinomycetes, fungi and viruses in protists, and the target microorganisms are mainly pathogenic bacteria.

The antibacterial is a preparation used to kill or inhibit the above pathogenic microorganisms on the transmission medium to make it harmless. That is, a chemical that is highly sensitive to some microorganisms, which cannot develop or inhibit their growth through physical or chemical reactions, and which can be added to the material in small amounts to give the material antimicrobial properties.
