Researchers from the @biomedizin.unibas.ch, at the @unibas.ch, present an antimicrobial single-cell microscopy-based method that measures antibiotic lethality in individual bacteria. 🔗 doi.org/10.1038/s415... @natmicrobiol.nature.com

In our new paper, we use structures, MD and kinetics to show that metformin inhibits by a distinct mechanism that more hydrophobic, less well tolerated, biguanides. www.nature.com/articles/s41...

We achieved this by using the enzyme Huc to oxidize ambient hydrogen. This results in a continuous low-level power from air and higher outputs with industrial waste gases.
