Scientists are using Escherichia coli bacteria to make fuels and chemicals from renewable sources like plants and waste. They have engineered E. coli to produce various products efficiently. The goal is to shift from using petroleum to more sustainable resources. This research shows that E. coli can be improved to use different renewable materials, like gases and methanol, for making fuels and chemicals. This work helps us understand how E. coli can help create a greener economy by using renewable resources effectively.
