Question

i)     Which bacteria transform acetic acid into biogas?              ​

Answer 1

Answer:

acidogenic bacteria transform the products of the hydrolysis into short chain volatile acids (acetic acid, propionic and butyric acid), ketones, alcohols, hydrogen and carbon dioxide. Acetic acid, hydrogen and carbon dioxide will be directly utilized by methanogenic bacteria.

Answer 2

Methanococccus and Methanobacillus are two species of bacteria that transform acetic acid into biogas.              ​

• Methanococcus and Methanobacillus have the ability to convert organic acids like acetic acid into biogas.

• The conversion requires the action of enzymes produced by these bacteria.

• Biogas is a mixture of methane and carbon dioxide. This is the main reason why the bacteria that have the ability to convert are named after 'methane'.

• The main use of this biogas is that it is a renewable resource that can be used in generating electricity, fuel for vehicles, etc.
