Question

Write the names of 5 beneficial bacteria and state their benefits .

Answer 1

Answer:

1. Lactobacillus acidophilus

These are the most friendly bacteria. Lactobacillus is the genus name and acidophilus is the particular strain. They are naturally present in dairy products, and are added to miso, tempeh, yogurt, and other dietary supplements for better results. They produce vitamin K, lactate, and hydrogen peroxide. In the human body, they are found in the oral cavity, intestine, vagina, etc. These areas have slightly acidic pH because of these microbes. This helps curb the overgrowth of pathogens. In the vagina, these bacteria produce lactic acid that prevents fungal growth. They are used to treat diarrhea too. Thus, the microorganisms help strengthen the immune system.

2. Tobacillus acidophilus

They belong to the genus Lactobacillus and are acid-loving bacteria. These are found in buttermilk, yogurt, sour cream, and frozen desserts. They convert sugar and carbohydrates into lactic acid, and hence are called "lactic acid bacteria." By lowering the pH and reducing the risk of growth of other organisms in the food through this process, they generate a fermented taste. This process is beneficial for people, as it prevents gastrointestinal infections. Anaerobes, that do not need oxygen to live, are helpful in the fermentation of vinegar, and also in the cheese-making process.

3. Acidophilus bifidus

They produce lactic acid and hydrogen peroxide. They help curb the growth of pathogens. Some lactic acid bacteria help reduce cholesterol levels by breaking down bile, thus restricting its reabsorption. They prevent the growth of hostile yeasts like Candida albicans. They cleanse the bloodstream by removing toxins and boost the immune system. While killing pathogens, antibiotics also kill helpful bacteria. Consumption of Bifidobacterium when on antibiotics can minimize the risk.

4. Lactobacillus reuteri

These are found in breast milk and gut flora. Milk products like yogurt and cheese are fortified with these.

5. Escherichia coli

They are present in the intestine, and are also known as enteric bacteria. Probiotic Escherichia coli Nissle 1917 is used to treat bowel diseases like ulcerative colitis, Crohn's disease, chronic constipation, irritable bowel syndrome, etc.
