Over the course of several months, researchers created Escherichia coli strains that consume carbon dioxide for energy instead of organic compounds. This achievement in synthetic biology highlights the incredible plasticity of bacterial metabolism and could provide the framework for future carbon-neutral bioproduction. The work appears November 27th in the journal Cell.

“Our main aim was to create a convenient scientific platform that could enhance CO2 fixation, which can help address challenges related to sustainable production of food and fuels and global warming caused by CO2 emissions,” says senior author Ron Milo, at systems biologist at the Weizmann Institute of Science. “Converting the carbon source of E. coli, the workhorse of biotechnology, from organic carbon into CO2 is a major step towards establishing such a platform.”

The biosynthetic diversity of the animal world

Secondary metabolites are often considered within the remit of bacterial or plant research, but animals also contain a plethora of these molecules with important functional roles. Classical feeding studies demonstrate that, whereas some are derived from diet, many of...
