A natural biocide that kills microorganisms on your hands?

Ginger and garlic. If you want to be efficient, mix minced ginger and garlic. This is a plant, and the pure natural is strong light and strong ultraviolet rays, what bacteria and viruses are hung up, and animal hemp, general animal saliva also has the ability to kill bacteria.

There are several commonly used Chinese herbal medicines that can be sterilized, what I will tell you in a few days, you don't rush to close the problem first.

It's too much trouble, you just pour some liquor.

Because there are many types of microorganisms, their viability is different, and it is difficult to say which disinfectant can completely kill all bacteria, and different types of disinfectants can effectively kill different microorganisms.

a. Oxidation: The sterilization mechanism is to release new ecological atomic oxygen and oxidize the active groups in the bacteria; Sterilization is characterized by fast and strong action, which can kill all microorganisms, including bacterial spores and viruses. It is mainly used for surface disinfection, such as chlorine dioxide, hydrogen peroxide, ozone, etc., and this kind of disinfectant is a sterilizing agent.

b. Aldehydes: the sterilization mechanism is to denature or alkylate proteins; Bactericidal characteristics are effective against bacteria, spores, fungi and viruses. However, the temperature has a greater effect. Such as formaldehyde, glutaraldehyde, etc. This type of disinfectant can be used as a disinfectant.

c. Phenols: The sterilization mechanism is to denature, precipitate or inactivate the enzyme system; Bactericidal characteristics are effective against fungi and some viruses.

d. Alcohols: The bactericidal mechanism is to denature proteins and interfere with metabolism; Bactericidal characteristics are effective against bacteria, but ineffective against spores, fungi, and viruses, such as ethanol, ethylene propyl alcohol, etc. This type of disinfectant is a medium-potency disinfectant and can only be used for general disinfection.

e. Alkalis and salts: the sterilization mechanism is to denature, precipitate or dissolve proteins; Bactericidal is characterized by killing bacterial propagules, but not bacterial spores, viruses and some microorganisms that are difficult to kill. The bactericidal effect is weak and has strong corrosiveness, such as nitric acid, caustic soda, salt, etc.

Can only be used as a general preventive disinfectant.

f. Halogens: The bactericidal mechanism is the active gene in the oxidized bacterium, which binds to the amino group to denature the protein. It is characterized by being able to kill most microorganisms, mainly surface disinfection, unstable in nature, and the sterilization effect is greatly affected by environmental conditions, such as sodium hypochlorite, "84" disinfectant, euchlorine, etc.

This type of disinfectant is a medium-effect disinfectant and can be used as a general disinfectant. g. Surfactants: The sterilization mechanism is to change the permeability of the cell membrane, so that the cytoplasm leaks, hinders respiration or denatures proteases.

Bactericidal characteristics are that it can kill bacterial propagules, but has poor effect on spores, fungi, viruses, and tuberculosis bacteria. The effect is good under alkaline and neutral conditions, such as Xinjieer, 100 poison killing, etc. This type of disinfectant is a low- to medium-efficiency disinfectant and can be used as a general disinfectant.

Several kinds of strong oxidizing water, such as 84 and hydrogen peroxide, can be used.

The chemical formula of hydrogen peroxide is H2O2, pure hydrogen peroxide is a light blue viscous liquid, which can be mixed with water in any proportion, and is a strong oxidant. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. In general, it will decompose into water and oxygen, but the decomposition rate is extremely slow, and the way to speed up the reaction is to add catalysts such as manganese dioxide or irradiate them with short-wave rays.

Chlorine-containing disinfectants (such as 84 disinfectant), peracetic acid, glutaraldehyde and other commonly used disinfectants are highly effective disinfectants, which can kill common infectious disease pathogens and are used to treat items contaminated by bacteria and viruses, and the effect is reliable.

However, peracetic acid, glutaraldehyde, etc., are mainly used by health professionals, and for the general population, 84 disinfectant can be selected, which is relatively simple to use and easy to purchase (generally sold in large supermarkets).

Just boil in boiling water for about ten minutes, safe and residue-free.

10.Which disinfectant is the best sterilization effect? The sanitizer with this ingredient is simply invincible!

The commonly used methods of sterilization include chemical reagent sterilization, radiation sterilization, dry heat sterilization, moist heat sterilization and filter sterilization. According to different needs, different methods can be used, such as medium sterilization, which is generally sterilized by moist heat, and air is sterilized by filtration. Heat sterilization Heat sterilization uses high temperature to denature all proteins in microbial cells, and enzyme activity disappears, resulting in cell death.

Usually there are dry heat, moist heat and intermittent heating to kill Mycomycetes. Dry heat sterilization directly uses flames to burn microorganisms to death (such as burning inoculation loops, glass slides, test tube mouths, etc.).Items that cannot be sterilized by flame are sterilized with hot air, and the items are heated to 160 170 for 90 minutes in an oven for 90 minutes, and this method is suitable for glass, metal and wood utensils.

Moist heat sterilization is sterilized by boiling water, steam, and vapor under pressure. Pasteurization is moist heat sterilization, this method has two ways, low temperature and long-term treatment: under the treatment for 30 minutes; High temperature short time treatment:

Treat at or slightly higher for 15 min. Among the above methods, the best effect is steam pressure sterilization, which can be sterilized by atmospheric steam or sterilized in a high-pressure steam pot (generally using 1 kg cm2), and its vapor temperature can reach 121, which can kill the heat-resistant spores within 30 minutes. However, for some substances that are easily destroyed by high pressure, such as some sugars or organic nitrogenous compounds, it is advisable to sterilize them under a pressure of 110 cm 2 (110) for 15 to 30 minutes.

Intermittent sterilization Intermittent sterilization is a method of steam sterilization once a day for 3 consecutive days. This method is suitable for substances that cannot withstand temperatures above 100 degrees and some sugars or proteins. Generally, it is sterilized with steam at normal atmospheric pressure for 1 hour.

The sterilization temperature does not exceed 100, which will not cause the destruction of sugars and other substances, and can kill the spores germinated during the intermittent culture, so as to achieve the purpose of complete sterilization. Radiation sterilization Radiation sterilization is a method of sterilization by using radiation under a certain branch. Ultraviolet rays are more commonly used, and others include ionizing radiation (rays accelerating neutrons, etc.).

Lasers with wavelengths between 25,000 and 80,000 nm also have a strong germicidal ability, with wavelengths of 26,500 nm being the most effective. Radiation sterilization is limited to a certain material, and it is difficult to use it widely due to the complexity of the equipment required. Osmotic Sterilization Osmotic sterilization utilizes a high osmolality solution for sterilization.

In a high concentration of salt or sugar solution, the cells are separated from the plasma wall due to dehydration, and cannot carry out normal metabolism, resulting in the death of microorganisms. Chemical Sterilization Most chemical agents have an antibacterial effect at low concentrations and bactericidal effects at high concentrations. 5% carbolic acid, 70% ethanol and ethylene glycol are commonly used.

Chemical sterilants must be volatile in order to remove residual drug residues from the sterilized material.

Microorganisms are divided into eukaryotic cells and prokaryotic cells, but most of them are aimed at prokaryotic cells, because if they are harmful to health, they are basically prokaryotes, and this fire extinguishing method is summarized in **. If it is a microbial fire extinguishing in the space, it can be sterilized with ultraviolet light, phenol fumigation, alcohol can be killed, high temperature can be killed, and chemicals are various antibiotics.

Inactivation refers to the use of physical or chemical means to kill viruses, bacteria, etc., without damaging their useful antigens in the body.

method. Inactivating the virus will destroy the high-level structure of the virus egg staring at Xunbai, and the protein no longer has physiological activity, so it loses its ability to infect, cause disease and reproduce, but the conventional inactivation does not affect the primary structure of the virus protein, which means that the sequence of the virus protein has not changed.

Immune system. There are two types of antigen recognition, one is a conformational epitope and the other is a linear epitope. Conformational epitopes are the three-dimensional structure of a protein, while linear epitopes are the sequence first-order structure of a protein. T cells.

It only takes the recognition of the linear epitope to receive the signal sent by the immune-presenting cells to Sun Ze, triggering an immune response.

So the inactivated virus is antigenic, but loses its infectivity. This is actually the manufacturing principle of many vaccines.

Sterilization. The basic microbiology technology that kills microorganisms in a certain substance by physical and chemical methods. The thoroughness of sterilization is limited by the sterilization time and the strength of the sterilant.

The resistance of the microorganism to the sterilant depends on the resistance of the original population density, the strain, or the environment. Sterilization is necessary to obtain a pure culture.

It is also an essential technology in the food industry and in the pharmaceutical field.
