- Streptomyces erythreus
- Saccharomyces cerevisiae
- Rhizopus arrhizus
- Lactobacillus
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding dhokla fermentation.
Dhokla is a fermented food product prepared from gram flour. Fermentation improves taste, texture, and nutritional value.
Step 2: Role of Lactobacillus.
Lactobacillus is a lactic acid bacterium that ferments carbohydrates in gram flour, producing lactic acid and causing the batter to rise.
Step 3: Evaluation of options.
(A) Streptomyces erythreus: Incorrect — known for antibiotic production.
(B) Saccharomyces cerevisiae: Incorrect — commonly used in bread and alcohol fermentation.
(C) Rhizopus arrhizus: Incorrect — a fungus used in other fermentations.
(D) Lactobacillus: Correct — responsible for fermentation in dhokla batter.
Step 4: Conclusion.
The organism that brings about fermentation of gram flour in dhokla dough is Lactobacillus.
Dhokla is a fermented food product prepared from gram flour. Fermentation improves taste, texture, and nutritional value.
Step 2: Role of Lactobacillus.
