Proteomics and metabolic modeling revealed that the 'knallgas' bacterium Cupriavidus necator utilizes only a fraction of its proteome and keeps large enzyme reserves as an adaption to variable environments.

The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO₂ fixation.

A bacterial CO₂ concentrating mechanism enables Escherichia coli to fix CO₂ from ambient air into biomass.

Achieving autotrophy in E. coli by introducing a small number of genetic changes crosses a milestone in engineering major metabolic transitions and paves a way for sustainable bio-production from CO₂.

An unexpected new biological function was discovered for the universally conserved cofactor lipoate, as lipoate-binding proteins proved essential for a novel wide-spread prokaryotic sulfur oxidation pathway.

Phylogenomics reveals the timeline over which marine bacteria and archaea colonized the oceans and shows the geological context of their diversification.
