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 is a type of beneficial bacteria that inhabits our gut and plays a role in maintaining a healthy digestive system. It helps in keeping disease-causing microbes in check by producing lactic acid and maintaining an acidic environment.

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.
