When it comes to bacteria, many people equate it with pathogenic bacteria and sterilize as much as possible. However, not all bacteria are harmful. There are many microorganisms such as bacteria that are beneficial to human health.
When it comes to bacteria, many people equate it with pathogenic bacteria and "sterilize" as much as possible. However, not all bacteria are harmful. There are many microorganisms such as bacteria that are beneficial to human health. They are generally divided into two categories:
The probiotics mainly refer to the screening of some functional lactic acid bacteria and yeasts.
Antibiotics are drugs that inhibit and kill all living substances at very low concentrations. For example, the various drugs we use to resist bacteria, viruses, and parasites, as well as anti-tumor drugs, all belong to the category of antibiotics. So antibiotics can kill probiotics.
Antibiotics are also medicines. After they enter the human body, they exert their therapeutic effects and also cause many adverse reactions. The most obvious is the increase in bacterial resistance. The intake of probiotics does not need to consider the issue of drug resistance, and there will be basically no side effects.
It's not. Bifidus factors or probiotic factors are substances that promote the proliferation of bifidobacteria or probiotics in the intestinal tract and belong to the category of prebiotics.
It can withstand the corrosion of gastric juice and bile, and reach the intestines in a living state. It can multiply in the intestine, and it has been proven by scientific experiments to improve the intestinal flora. It can also ensure safety, which is originally a kind of intestinal flora. Survive in food and can maintain effective bacterial count; inexpensive and easy to handle. Only when the above conditions are met can it be called a probiotic.
We live in an era of fierce competition, with heavy pressure, worsening environment, serious pollution, unreasonable diet structure, excessive consumption of meat and fats, and insufficient intake of cereals, over-exquisite food processing, etc. These changes in diet and environment have caused great changes in the flora in our body, including their composition, quantity and balance. Put us in a sub-healthy state. The imbalance of the intestinal flora in the body will cause a series of potential diseases. Therefore, it is very necessary for us to supplement beneficial bacteria.
Vulnerable groups: middle-aged and elderly people, babies, children and women
People in urgent need of supplementation: 1. People who use antibiotics 2. People who smoke and drink regularly 3. People who have habitual constipation 4. Office workers, computer workers 5. People with cardiovascular disease, liver disease, cancer chemotherapy and other diseases
The Naming and Characteristics of Restriction Endonucleases
Restriction enzymes, also known as restriction endonucleases, are enzymes that cut double-stranded DNA. Its cutting method is to cut the bond between the carbohydrate molecule and the phosphoric acid, and then create a nick on each of the two DNA strands without damaging the nucleotides and bases.
Introduction to Classification and Application of Cellulase
The optimum pH of cellulase is generally 4.5 to 6.5, which acts on cellulose and products derived from cellulose. Microbial cellulase is of great significance in converting insoluble cellulose into glucose and destroying cell walls in fruit and vegetable juice to improve the yield of juice.
Which Enzyme Preparations Are Often Used in Fruit and Vegetable Processing?
The so-called fruit and vegetable processing means to maximize the nutrient content of the fruit and vegetable through various processing methods, improve the edible value, and make the color, aroma and taste of the processed product more perfect.
