Question

Which one of the following pairs is wrongly matched?

• A. Coliforms - Vinegar
• B. Methanogens - Gobar gas
• C. Yeast - Ethanol
• D. Streptomyces - Anitbiotics

Answer 1

The correct option is A

Coliforms - Vinegar

Coliform bacteria are defined as rod-shaped Gram-negative non-spore forming and motile or non-motile bacteria which can ferment lactose with the production of lactic acid and gas when incubated at 35–37°C.
Methanogens play a major role in the production of gobar gas or Biogas, whereas yeast and Streptomyces are essential for the production of ethanol and antibiotics, respectively.
