Elaborate on the yeast family
In the long history of human civilization, genealogy is the most direct testimony of the continuation of a family. You may not know that microbes also have their own family tree. According to a series of classification indicators such as morphological characteristics, physiological and biochemical characteristics, genetic characteristics, and reproductive characteristics, these little guys that we cannot see with the naked eye belong to different circles, phylums, classes, orders, families, genera, and species. Microorganisms can be divided into two systems: prokaryotes and eukaryotes. We often say that bacteria belong to the world of prokaryotes, and eukaryotes mainly include all kinds of fungi, such as molds and yeasts. In the fungal world, mycophyta, ascomycetes, yeast order, yeast family, yeast genus, there are a group of yeasts-some bring delicious taste on the tip of the tongue for humans, while others cause no small trouble for humans . Today, I, Sherlock Holmes, will unveil the mystery of the yeast family and take you in-depth understanding of the stories behind the members of the family.
Yeast is a type of single-cell eukaryotic microorganism that can ferment sugars. It is rich in amino acids, vitamins, enzymes and other substances, and has been widely used in animal husbandry production. Yeast cells have a width of about 2 to 6 microns and a length of 5 to 30 microns. The individual morphology includes spherical, oval, and oval shapes. They are homes all around the world, they are wandering everywhere, and do not have high requirements for the living environment. They can survive in the air, soil, water, human and animals. In a sugar-rich environment, such as some fruits (grapes, apples) and some plant secretions, they can quickly “fall into the ground” as if they fell into a honeypot. The presence or absence of oxygen cannot limit the survival of yeasts. Under anaerobic conditions, yeasts can change from aerobic to anaerobic respiration.
Contributing delicious baking yeast and Saccharomyces cerevisiae
Speaking of the yeast that contributes the most to our human beings, there is no yeast commonly used in fermented products. The baker’s yeast we are referring to here refers to a class of yeasts for fermented rice noodle products, not a professional classification in microbial taxonomy. Baker’s yeast is essential in almost every home kitchen, and is widely used in some fermented foods such as buns, breads, and cakes. The baker’s yeast can cause the dough to produce a large amount of carbon dioxide. Due to the formation of the gluten mesh structure, these gases are retained in the mesh structure, thereby forming the soft taste and unique aroma of the fermented food.
Saccharomyces cerevisiae is a yeast used for brewing and converting sugars into alcohol. In the absence of oxygen, Saccharomyces cerevisiae obtains energy by converting sugars into carbon dioxide and ethanol (alcohol), and the fermentation products are various wines-beer, white wine, red wine, etc. The carbon dioxide produced by beer yeast during the brewing process is the cause of foam in the wine.
Bladder yeast for intestinal health
Bladder yeast is the only intestinal fungus currently known to be beneficial to the human body. Blairella is a non-pathogenic yeast belonging to the genus Saccharomyces cerevisiae, which was isolated from the peel of tropical fruit in 1923. Blax does not exist in the human intestinal flora. Usually the drug is taken continuously for 3 days, and the intestine can reach a stable concentration. It is completely cleared from the feces 2 to 5 days after stopping the drug, and there is no genetic material transmission with bacteria in the intestine.
The intestinal system of a healthy human body contains trillions of microorganisms. The dynamic balance of different types of microorganisms can form a natural protective barrier against external invasions and maintain intestinal health. Bladder yeast can temporarily act as beneficial bacteria in the intestinal tract, help the gastrointestinal tract to re-establish and maintain a balanced micro-ecological environment, which is beneficial to the early repair of the gastrointestinal mucosa. Therefore, it has a certain effect on the treatment of inflammatory bowel disease. Inflammatory bowel disease is a chronic intestinal inflammatory disease, mainly including ulcerative colitis and Crohn’s disease.
Some studies have pointed out that in the treatment of pediatric rotavirus enteritis, Bladder yeast can reduce antidiarrheal time, length of hospital stay, and improve the efficiency of treatment. Rotavirus is a common clinical pathogen. At present, there is no effective therapeutic drug. The clinical treatment is mainly antiviral and corrects water and electrolyte disorders.
In addition, the bacteria can inhibit the growth and reproduction of intestinal pathogenic bacteria, promote the intestinal epithelial cells to mature, accelerate the weight gain, and also have an effect on improving the intestinal microbial barrier and anorexia symptoms in children with anorexia.
Candida albicans causing vaginitis
Candida albicans, the scientific name of Candida albicans, has low nutritional requirements and can grow on general bacterial culture media. The morphology of colonies varies greatly depending on the culture media. The bacteria particularly love “eat sugar”. When the bacteria is cultured in the laboratory, the glucose content in the medium can reach more than 60%. The bacterium is notorious in the microbiological world, and when humans are weak, it takes the opportunity to cause trouble.
Among the diseases caused by Candida albicans, the most common is vaginal inflammation in women. The disease is mainly caused by Candida infection in the vulva and vagina. It is relatively common in the clinic. About 75% of women have had the disease in their lifetime, and 40% to 50% of women have relapsed. Studies have shown that vaginal irrigation, prolonged use of contraceptives or antibiotics, diabetes and pregnancy are closely related to the occurrence of the disease. Patients with this disease will experience itching of the vulva, severe pain, restlessness, leucorrhea that is egg white-like, bean dreg-like, or thick white curd-like, and increased; if the urethral infection occurs, it is accompanied by dysuria, frequent urination, and even hematuria . Gynecological examination showed redness and swelling of the vulva, often with scratches, and clinical symptoms such as superficial ulcers in the acute stage. The bacteria can also cause skin and soft tissue and abdominal infections, as well as sepsis, endocarditis, and meningitis.
Candida is the most common deep fungus, and it is also a flora that is normally distributed in the human body. Candida is present in the vagina of about 10% to 30% of women, but the amount of bacteria is relatively small and will not Cause symptoms. Candida genus will multiply after encountering a suitable environment. It changes from yeast state to mycelium state, the virulence increases, and the patient’s immune function is impaired, and eventually a series of pathological reactions occur.
Microbes are very smart. If the environment is not suitable for its growth, the microorganisms choose to enter a dormant state. When the environment is suitable, microorganisms can multiply. Therefore, if our body is in poor condition, such as the hot and humid betting and the cold and cold betting from the perspective of traditional Chinese medicine, and the local environment of the body becomes suitable for the growth of Candida albicans, they will accelerate the reproduction, which will cause the corresponding symptoms in the human body. . According to the Chinese medicine treatment idea, patients can use some Chinese medicine to clear the heat, dryness and dampness to remove the dampness, heat, and coldness in the body. When the local environment of the body changes, which is not conducive to the survival of Candida albicans, they will be driven away, and we have achieved the goal of healing.
