Microbial fuel cells are considered a source of sustainable energy. Why?
1) They use living organisms as catalysts to generate electricity from certain substrates.
2) They use a variety of inorganic materials as substrates.
3) They can be installed in waste water treatment plants to cleanse water and produce electricity.
Which statement(s) given above is/are correct?
Explanation:
1st statement is correct regarding Microbial fuel cells i.e. They use living organisms as catalysts to generate electricity from certain substrates.
A microbial fuel cell (MFC), or biological fuel cell, is a bio-electrochemical system that drives an electric current by using bacteria and mimicking bacterial interactions found in nature. MFCs can be grouped into two general categories: mediated and unmediated.
