Apparently, there are good and bad e-coli bacteria, according to the New Scientist this week:
CO2-guzzling bacteria made in the lab could help tackle climate change
Bacteria have been rewired to live off carbon dioxide and they could be used to produce biofuels in a more sustainable way.
Specific strains of Escherichia coli bacteria are often used to make biofuels and other chemicals, but they normally feed on sugar. Ron Milo at the Weizmann Institute of Science in Israel and his colleagues have managed to make E. coli consume CO2 instead…

And there are many more such ideas being developed:
