Answer the Following. Which Fuels Can Be Obtained by Microbial Processes? Why is It Necessary to Increase the Use of Such Fuels? - Science and Technology 2

Short Note

Which fuels can be obtained by microbial processes? Why is it necessary to increase the use of such fuels?

Solution

There are different kinds of fuel which can be produced with the help of microbes. Some of the examples of such fuels are:

1. Ethanol- It is a byproduct which is produced during fermentation of molasses by Saccharomyces. It is a type of alcohol and is a clean (smokeless) fuel. It is mixed with petrol and diesel to prevent vehicular emission.

2. Methane- Methane is a gaseous fuel which is obtained by microbial anaerobic decomposition of urban agricultural and industrial waste.

3. Hydrogen fuel: Hydrogen is released during bio-photolysis of water in which bacteria perform photoreduction. It is considered as the fuel of future as it is non polluting and an efficient fuel.

Fuels which are obtained from fossil fuels are non renewable and also polluting. These fuels like hydrogen, ethanol, methane are the future fuels as they burn cleaner with more less same efficiency and are renewable. Thus, their use needs to be promoted further.
