Which biochemical pathway did the researchers modify to produce higher alcohols in E. coli

Answer: Amino acid metabolism

Explanation:

Biosynthesis approaches for the production of the higher higher alcohols as a source of alternative fuel. There are various types of method by which the alcohol production can be done in laboratory conditions.

The name of the method is amino acid metabolism. In this case the synthesis of the alcohol can be increased in the bacteria named E. coli.

In invivo conditions the whole cell mutagenesis is done in E. coli to increase the synthesis of alcohol.
