Question

Which of the following plays a significant role in our stomach in checking disease-causing microbes?

• A. Penicillium notatum
• B. Monascus purpureus
• C. Trichoderma polysporum
• D. Lactobacillus

Answer 1

The Correct Option is D

Lactobacillus plays a significant role in our stomach in checking disease-causing microbes. Here's why: 

• Lactobacillus is a type of bacteria found in the human gut and is known as a good bacterium or probiotic.
• It helps maintain the natural balance of microorganisms in the intestines, crucial for proper digestion and immune function.
• By producing lactic acid, Lactobacillus creates an acidic environment that inhibits the growth of harmful pathogens.
• This not only helps in digestion but also prevents gastrointestinal infections.

Therefore, among the options provided, Lactobacillus is the key microorganism aiding in the control of disease-causing microbes within our stomach.

Answer 2

Lactobacillus is a genus of bacteria that plays a significant role in microbiology, particularly in the fermentation process. These bacteria are known for their role in producing lactic acid by fermenting sugars, which is essential for the production of foods like yogurt, cheese, and sauerkraut. Lactobacillus is considered beneficial for gut health, contributing to a balanced microbiome.

• Penicillium notatum is a mold that produces the antibiotic penicillin, which is used to treat bacterial infections, not for causing microbes.
• Monascus purpureus is a fungus that is used in the production of red yeast rice, but it is not associated with causing microbes.
• Trichoderma polysporum is a fungus used in biocontrol, not in causing microbes.
