Beg! Examples of microbes around us at work

Yeast: used to make bread, steamed bread, wine (red wine, white wine......）

How it works: Sugars are converted by yeast into water, carbon dioxide and alcohol (alcohol is volatilized when steaming steamed buns and baking bread).

Lactic acid bacteria: to make yogurt and kimchi.

Principle: Glucose is converted into lactic acid by the action of lactic acid bacteria.

Aspergillus: to make fermented bean curd and soy sauce.

Principle: Starch is converted to glucose by aspergillus.

Acetic acid (bacillus): to make vinegar.

In addition, a variety of molds are required to make the sauce, and koji is used to make sweet sake.

In medicine, E. coli is used to produce drugs in large quantities (e.g., E. coli to produce insulin (a protein), and some fungi can kill certain disease-causing bacteria (e.g., penicillin, tetracycline).

E. coli in the human body lives in the large intestine of the human body and provides the body with some vitamins (such as vitamin D).

In terms of environmental protection, there are a large amount of organic matter such as organic acids and amino acids in some sewage, which can be used as food for bacteria. In the absence of oxygen, some bacilli and methane are fermented to break down these substances, and the methane produced can be used for lighting, heating or power generation, while wastewater is also purified, and some bacteria also help these substances survive in the presence of oxygen, breaking down organic matter into carbon dioxide and water.

Further afield, people use Beauveria bassiana and Bacillus thuringiensis to control insect pests, reduce the use of pesticides, and reduce environmental pollution.

In short, bacteria and fungi decompose organisms into carbon dioxide, water, and inorganic salts, which can be absorbed and utilized by plants, and then produce organic matter, and microorganisms play an important role in the circulation of carbon dioxide and other substances in nature.

To give three examples: 1. Yeast is used to make wine or make wine, etc., 2. Lactic acid bacteria are used to make yogurt or kimchi, etc., 3. Corynebacterium glutamate is used to make monosodium glutamate or chicken essence.

The MSG is fermented by microorganisms, and there are also yogurt, beer, etc., and the effect of microorganisms is called big!!

Dead bodies will decompose.

Ferment. He's going to make you sick. Wait a minute.

The microbes in your gut are mutually beneficial and symbiotic with you.

Such as: profit. 1.Microorganisms are used to ferment liquor, vinegar, bread, steamed bread and other foods.

2.Cosmetology using metabolites of microorganisms: toxins of Clostridium botulinum;

3.Oral liquid that uses probiotic microorganisms to regulate human immunity and increase resistance: bifidobacteria, etc.

4.To make yogurt and cheese: lactic citrus;

5.Protease produced by bacillus: plus enzyme laundry detergent.

Generally, there are 5 types.

1 Mutual: two organisms that can live alone, when they are together, through their respective metabolic activities in favor of each other, or in favor of one of the other's way of life. "It can be divided and combined, and the score is good".

Examples of mutualism: normal microflora in humans and intestines, normal microflora hinders and inhibits foreign pathogenic bacteria; Produces amylase, protease that aid digestion; decomposition of toxic substances; nutrients, which provide a good environment and nutrients such as inorganic salts.

2. Symbiosis: Two organisms live together, divide labor and cooperate with each other, and become one in an extremely close mutual relationship. "Interdependence is fate, inseparable".

Examples: Lichens: fungi and algae; rhizobia and plants; Ruminants (bovine) and rumen microorganisms.

3 Parasitism: A kind of interrelationship in which a small organism lives in the body or body surface of another larger organism, takes nutrients from it to grow and reproduce, and causes the latter to suffer losses or even be killed.

Examples: Humans and pathogenic microorganisms.

4 Antagonism: A kind of interrelationship in which specific metabolites produced by one organism can inhibit the growth of other organisms or even kill them.

Examples of antagonism: Penicillium produces penicillin; Lactic acid bacteria produce acid.

5 Predation: The interrelationship between one large organism directly catching and devouring another small creature to meet its nutritional needs.

Examples of predation: Protozoa engulf bacteria.

Parasitism: such as making people and animals sick.

Symbiosis: such as microorganisms in the intestines of animals, Chlamydomonas and fungi, legumes and rhizobia.

Escherichia coli, a beneficial bacterium in the human intestines, microorganisms in the soil promote soil fertility, and Vibrio cholerae can cause illness in humans.

There is a parasitism of E. coli in the rectum of humans.

Rhizobia in the roots of soybeans.

Food: brewer's yeast fermentation produces beer, bread, etc.

Drugs: antibiotics, interferons, vaccines, etc.

Cosmetics: collagen, botulinum toxin, etc.

Metallurgy: the use of microbial respiration.

Environmental remediation: megalophiles deal with pollution caused by oil spills.

Fungi mushrooms.

Bacteria milk.

Viruses infectious diseases.

Application of genetically transgenic animals, plants, microorganisms, and technologies.
