Applied Microbiology
A branch of biology that studies the commercial and practical uses of microorganisms in areas like food, medicine, and agriculture.
Dairy Products
Products like yogurt, butter, and cheese produced through the fermentation of milk using specific bacteria such as Lactobacillus.
Antibiotics
Carbon compounds produced by bacteria and fungi that destroy or inhibit the growth of harmful disease-causing pathogens.
Probiotics
Preparations containing live, useful bacteria (like Lactobacillus acidophilus) that improve gut health and immunity.

Frequently Asked Questions
What is the main difference between useful and harmful microbes?
Useful microbes help in food production, medicine, and environmental cleanup (e.g., Lactobacillus in curd), while harmful microbes cause diseases in humans, animals, and plants.
Why is yeast added during bread making?
Yeast ferments sugars in the dough to produce carbon dioxide gas, which gets trapped and makes the bread rise, becoming spongy and soft.
What are probiotics and why are they good for health?
Probiotics are dietary supplements containing live friendly bacteria that improve digestion, maintain gut flora, and boost the immune system.
