Show Hint

Updated On: Oct 22, 2026
- Lactobacillus and Yeast
- Penicillium and Yeast
- Microspora and E.coli
- Rhizopus and Lactobacillus
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Think of kitchen processes that need microbes:
Milk is set into curd, and dough for bread, idli and dosa batter is made to rise.
Each process uses a known microbe.
Step 2: Match the microbes:
Lactobacillus is a lactic acid bacterium. It turns milk into curd by making lactic acid.
Yeast (Saccharomyces cerevisiae) ferments sugar and releases carbon dioxide, which puffs up dough.
Step 3: Check the wrong options:
(B) Penicillium is a mould used to make the antibiotic penicillin and to ripen some cheeses. It is not a common kitchen microbe.
(C) Microspora is not a kitchen microbe, and E. coli lives in the gut and is not used in cooking.
(D) Rhizopus is a bread mould that spoils food, so it is not used in the kitchen. Only Lactobacillus in it is right.
Final Answer:
Lactobacillus (curd) and yeast (dough) are used in the kitchen. The correct option is (A).
