Mycoplasma is sensitive to 75% ethanol, due to the fact that 75% ethanol can coagulate and denature the proteins within the mycoplasma, leading to complete killing of the mycoplasma. Mycoplasma can be disinfected with coal phenol soap solution, 2.5% coal phenol soap solution is also known as Lysol clinically, often used to kill a variety of pathogenic bacteria, including Mycobacterium tuberculosis, Mycoplasma, Chlamydia and so on, so it also has a better disinfection of Mycoplasma. 84 solution due to the fact that it has hypochlorite, hypochlorite has an oxidizing and reducing effect, hypochlorite can penetrate deep into the cells to act on the enzymes within the mycoplasma, making the Mycoplasma mycoplasma enzyme denaturation, so that mycoplasma kill, the same hypochlorite root has oxidizing, can penetrate into the mycoplasma mycoplasma enzyme oxidation, so that mycoplasma mycoplasma kill. All of the above disinfectants have good killing effect on mycoplasma, but they can not be used in the body, and can only be used for instrument disinfection.
