Question

Which of the following bacteria are used to degrade the fermented products?

(a) Methanogenic bacteria

(b) Sulphate reducing bacteria

(c) Carbon degrading bacteria

(d) Hydrogen producing bacteria

This question was posed to me in an interview.

I'd like to ask this question from Anaerobic Bacterial Degradation of Biopolymers in portion Biodegradation of Organic Pollutants of Environmental Biotechnology

Answer 1

Right answer is (a) Methanogenic bacteria

The explanation is: Methanogenic bacteria and acetogenic bacteria can further degrade the fermented products to methane, Sulphate reducing bacteria reduce Sulphur, Carbon degrading bacteria degrade carbon, and Hydrogen producing bacteria forms hydrogen.
