What is the difference between bactericidal and bacteriostatic effect?

Sterilization: The function of killing microbial trophic bodies and propagules is called sterilization.

Fungicide: The preparation used to kill or inhibit the growth of microorganisms is called fungicide. The "sterilization" in biocides does not necessarily need to kill microorganisms.

Most fungicides only inhibit the growth and proliferation of microorganisms; The magnitude of the effect depends on the concentration of the biocide and the sterilization time.

bacteriostatic; The effect of preventing or inhibiting the growth and reproduction of microorganisms is called bacteriostatic.

Antiseptic: It can prevent or inhibit the growth of microorganisms under the action of certain chemical substances and physical factors.

Prevent food spoilage or mildew of other substances.

Bacteriostatic agents or preservatives: drugs used to suppress bacteria.

Antibacterial: The antibacterial and bactericidal effects are collectively called antibacterial.

Antimicrobials: Chemicals that keep the growth or reproduction of certain microorganisms (bacteria, fungi, yeasts, algae, viruses, etc.) below the necessary level for a certain period of time. Anti-insulants are a new type of additives with antibacterial and bactericidal properties.

Antimicrobial agents should have the following characteristics: antibacterial ability and broad-spectrum antibacterial properties; Special effect, that is, washing resistance, wear resistance, long life; Weather resistance, that is, heat resistance, sun resistance, should not be decomposed and failed; Good compatibility or processability with the substrate, that is, easy to add to the substrate, no discoloration, no reduction in product value or aesthetics; It is safe, harmless to health, and does not cause pollution to the environment; Cells are less susceptible to drug resistance.

Antibacterial: antibacterial and bactericidal properties; It is antibacterial. The quality of antimicrobial activity depends mainly on the antimicrobial agent used.

The effect of antimicrobial agents on microorganisms is closely related to the concentration of antimicrobial agents and the length of time of action. Many drugs only have an antibacterial effect at low concentrations, and can have a bactericidal effect when the concentration increases or the action time is long.

Broad-spectrum antibacterial: Antibacterial materials and products should have antimicrobial effect on a variety of microorganisms. Such as:

Escherichia coli, Staphylococcus aureus, Bacillus gunweed, Garcinia cambogia, Rhodococcus purpurococcus, Candida albicans, Pyogenes aeruginosa, Aspergillus niger, Aspergillus flavus, Aspergillus terraformis, Budding Brachypoccus, Penicillium wansei, Penicillium cylinformis, Trichoderma viridus, Bulbous shell, Plum Qinglei and other harmful microorganisms have a strong inhibitory effect.

Commercial sterility: refers to the fact that canned food does not contain pathogenic microorganisms after moderate sterilization, nor does it contain non-pathogenic microorganisms that can multiply in it at normal temperatures. This state is called commercial sterility.

What is the difference between bactericidal and bacteriostatic effects of fungicides? : The virulence of fungicides to viruses is manifested in two ways: bactericidal effect and bacteriostatic effect.

Fungicides have many functions, and the simple explanation is to kill some bacteria and avoid the impact of bacteria on crops. There are many types of bacteria, and different bacteria can have different effects on crops, such as root rot, which is also a disease caused by bacteria and fungi. If the bacterium is not killed in time and is not treated with fungicides, it is likely to cause the entire crop to wilt, and the crop will cause direct economic losses to the grower after the crop wilts.

If there is a fungicide at this time to effectively kill some bacteria and avoid crop rot and death, then economic losses can be avoided, after all, after the bacteria are killed, it can continue to grow, and even flowering and fruiting will not cause economic losses. <>

Fungicides can effectively protect crops and recover faster. Some crops suffer from some bacterial diseases, then there will be some leaf wilting, or the leaves appear hollow, if spraying some fungicides to kill some bacteria, then the leaves of crops will not continue to be invaded by this bacteria, so that the growth of crops can be restored faster, otherwise it will affect the appearance, affect the flowering and fruiting of crops. <>

The early use of fungicides can effectively protect crops from harm。Fungicides have two effects, one is a protective fungicide, and most of us will use a protective fungicide when we use it for early prevention. The use of this protective fungicide in advance can effectively avoid the breeding of some bacteria, and the so-called prevention is greater than **, so the use in advance can reduce the damage of crops.

As a grower, planting crops is nothing more than hoping that crops can grow more luxuriantly, so that there will be no pests and diseases, so that there can be fruits to harvest. If there is a bacterial disease, it will not only affect the appearance of the crops, but also directly affect the income of their pockets.

According to the personal information, there are two modes of action of fungicides: one is a protective fungicide, and the other is a systemic fungicide. Fungicides are divided into **, except for agricultural antibiotics, which are bio-derived fungicides, the main varieties are chemically synthesized fungicides, and fungicides are a class of agents used to prevent and control plant diseases.

Fungicides can cause damage to many different sources, including the agent itself, different crop sensitivities, the growth stage of the crop and climatic conditions.

The difference between sterilization and disinfection is as follows:

1. Different degrees:

Disinfection: Disinfection only needs to kill or remove disease-causing microorganisms so that their number is reduced and they no longer cause human diseases.

Sterilization: Sterilization requires the killing or elimination of not only pathogenic microorganisms, but also all microorganisms, including non-pathogenic microorganisms.

2. Different methods:

Disinfection: Disinfection treatment methods include ultraviolet disinfection, ozone disinfection, chlorine-containing disinfectant, pasteurization, etc.

Sterilization: Sterilization treatment methods include physical and chemical methods, including heat sterilization, radiation sterilization, microwave sterilization, plasma sterilization, dry heat sterilization and autoclave sterilization, and chemical methods include aldehydes, alkylating agents, etc.

3. Differences in application:

Sterilization is mainly used in hospitals for the treatment of medical supplies and industrial products that enter the sterile tissues and organs of the human body. Disinfection is used in daily life and workplaces, and is also used in the treatment of general places and items in hospitals.

Choose two different treatment methods. Sterilization is more demanding than disinfection, and it is difficult to handle. When sterilizing, it is necessary to choose physical methods or chemical sterilizers, which can kill the most resistant microorganisms (bacterial spores), and only physical methods, chemical disinfectants or biological disinfectants need to be selected when disinfection, which have a certain bactericidal effect.

The use of sterilization treatment methods to disinfect is not only unnecessary for killing chickens with cattle knives, but also produces *** friends that should not have happened; If the sterilization treatment method is used for sterilization, it may result in sterilization failure.

Sterilization, bacteriostaticSterilizationThe concept of antibacterial should be clearly distinguished

Sterilization: The use of strong physical and chemical factors to make all microorganisms inside and outside any object permanently lose their ability to grow and reproduce.

Sterilization: Sterilization refers to the killing of objectsPathogensThe object also contains spores, non-pathogenic bacteria such as spores, and the difference between sterilization and sterilization lies in this.

Antibacterial: Inhibition of the growth and reproduction of bacteria and fungi through a series of physical and chemical methods.

Antibacterial: It is a general term for bactericidal and bacteriostatic. In fact, it is a general noun, including sterilization, sterilization, disinfection, bacteriostatic, mildew, antiseptic, etc., the process of using chemical or physical methods to kill bacteria or hinder the growth and reproduction of bacteria and their activity.

Sterilization: basically equivalent to sterilization.

After reading the above introduction, is it a bit messy, in fact, it can also be understood so simply: sterilization, sterilization, and sterilization basically mean the same thing, that is, to kill bacteria; Bacteriostatic only inhibits the growth and reproduction of bacteria, and does not necessarily kill bacteria; Antimicrobial is a general term for bactericidal and bacteriostatic.

The sterilization rate is as high as the sterilization data has been rigorously tested

Manufacturers advertise that the sterilization effect of the product is good, and the sterilization rate is generally noted at the back, for example, the more 9 after the decimal point, the better the sterilization effect. Note that the number of "9" is not something that can be added casually, and there are strict tests and inspection standards. Don't look at the back of only one more 9, but for hundreds of millions of bacterial families, the difference is quite considerable, a fairly large number, indicating that its sterilization effect is not in the same order of magnitude.

Above. Modern home life has long been inseparable from all kinds of household appliances, many household appliances have brought great comfort and convenience to people's lives, liberating their hands, saving time and energy, and enjoying quality life. Among them, health is always the first priority, whether it is a refrigerator related to dietDishwasherI believe that in the future, there will be more advanced sterilization technology integrated into various household appliances to bring all-round care for physical health!

Generally, disinfection can be divided into two categories: epidemic-source disinfection and preventive disinfection.

Types of disinfection.

There are two types of disinfection of the source of the epidemic and preventive disinfection, and the disinfection of the source of the epidemic is divided into two types: disinfection at any time and disinfection at the end of the day. It can also be divided into high-level disinfection, medium-level disinfection and low-level disinfection according to the level of disinfection.

Disinfection of epidemic foci refers to disinfection of areas where there are infectious agents (patients or pathogen carriers) to avoid the spread of pathogens. The disinfection of the foci of the epidemic is divided into two types: disinfection at any time and terminal disinfection. Disinfection at any time refers to the timely killing and elimination of pathogenic microorganisms discharged from pollution sources.

Terminal disinfection refers to the thorough disinfection of the original place of residence of the infectious agent after hospitalization and isolation, recovery or death, in order to completely eliminate the pathogenic microorganisms left behind by the infectious disease. After the source of infection in the hospital is isolated and discharged, the disinfection of items and wards is also terminal disinfection.

Preventive disinfection refers to the disinfection of items, places and human bodies that may be contaminated with pathogens without the detection of the source of infection. For example, disinfection of public places, disinfection of means of transport, disinfection of drinking water and utensils, and washing hands before and after using the toilet are all acceptable. In hospitals, the operating room is disinfected, and the hole of patients with severe immune compromise is raised, such as the preventive isolation and disinfection measures of bone marrow transplant patients.

Ordinary cleaning products can often see the words antibacterial, sterilization, etc., what is the difference between bacteriostatic and sterilization?

Bacteriostatic means to inhibit the growth of bacteria, bacteriostatic is to inhibit bacteria from continuing to multiply, and sterilization is to destroy the structure of bacterial cells and let bacteria die. Bacteriostatic and sterilization are just one word difference, which can be understood literally, one is to kill bacteria, and the other is to inhibit the growth of bacteria.

The difference between bacteriostatic and bactericidal is well understood, and the difference between inhibiting the growth of bacteria and killing bacteria. For bacteriostatic agents, it has an effect on pathogenic bacteria in the body, inhibits the growth of bacteria, solves the environment for its growth, and eliminates pathogens, while sterilization is only to kill the new bacteria that grow. Bactericide is a drug that kills bacteria, bacteriostatic is to inhibit the growth and reproduction of bacteria, so that bacteria are in a dormant state, once bacteria wake up from a dormant state, they will grow and multiply again, sterilization is to eliminate the root of the disease, and bacteriostatic is only to eliminate**.

The difference between the twoThe differences between disinfection and bacteriostatic are as follows.

1. The mode of action is different. Disinfection is used to kill microorganisms on the vector to disinfect or sterilize, but not necessarily to kill bacterial spores. Bacteriostatic works by inhibiting the reproduction of bacteria.

2. Different fields of use. Disinfection is often used for wound disinfection or sterilization of the human body to prevent infection and achieve the effect of antibacterial from the side. Due to its high safety and antibacterial effect, bacteriostatic is widely used in many fields such as antibacterial, antifungal, and disinfection.

3. The difference between ingredients. Disinfection is usually achieved by chemical methods, and antibacterial is mainly natural plant ingredients to achieve the effect of inhibiting bacterial reproduction.

Difference Between Fungicide and Bacteriostat:

First, the mode of action is different.

Bacteriostatic agents work by inhibiting the growth of bacteria. Fungicides destroy the cell structure of bacteria and cause bacteria to die. One is to kill bacteria, and the other is to inhibit growth.

Second, the field of use is different.

Due to its high safety and antibacterial effect, antibacterial agents are widely used in many fields such as antibacterial, mildew, disinfection, etc., and are ideal antibacterial agents for lotions, wet wipes, sanitary napkins, oral products, hand sanitizers, melon and fruit preservation and disinfection, environmental disinfection, etc.

Whereas, biocides can control or kill microorganisms, bacteria, fungi, and algae in water systems. The main areas are agricultural fungicides and industrial fungicides.

3. The difference between ingredients.

Bacteriostatic agents are mainly natural plant ingredients to inhibit the reproduction of bacteria, while fungicides are mainly used to destroy bacteria through their chemical components.
