Cyanobacteria have been engineered to produce isobutanol directly. what advantage does this have over other alternative biofuels?

Multiple processing steps can be avoided if the fuel is obtained directly.

Explanation:

Cyanobacteria can be used to derive the fuel like isobutanol directly. This process avoids many processing steps which lies in between.

By avoid so many steps we can save the time, money and other resources which is required in production of other alternative biofuels.

This is a very economical way by which fuel is produced with very less efforts. This will also help in production of more and more fuels without spending much on its processing.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
