Question

• A. Acidogenesis $ \rightarrow $ Solublisation $ \rightarrow $ Methanogenesis
• B. Solublisation $ \rightarrow $ Acidogenesis $ \rightarrow $ Methanogenesis
• C. Methanogenesis $ \rightarrow $ Solublisation $ \rightarrow $ Acidogenesis
• D. Acidogenesis $ \rightarrow $ Methanogenesis $ \rightarrow $ Solublisation

Answer 1

Answer: (B)

Biogas is a type of biofuel having a mixture of gases which is naturally produced by decomposition of organic matter by anaerobic process. It mainly contains methane and carbon dioxide.
The biogas production involves the following three proceses:
$1.$ Anaerobic digestion: The species of Clostridium and Pseudomonas anaerobically digest the waste and the complex insoluble polymers are convered into monomers. This step is also called solubilization.
$2.$ Acidogenesis: The monomers from previous step is changed to organic acids by acidogenic bacteria
$3.$ Methanogenesis: The last step of biogas production. Methane is produced from the organic acids along with carbon dioxide
