The paper reports the functional expression of a Mo-dependent formate dehydrogenase in E. coli under aerobic conditions, showing growth on formate as sole energy source and identifying mutations in a formate transporter gene as key to adaptation.

This paper investigates the pleiotropic effects of the AcrAB efflux pump in Photorhabdus laumondii, showing it influences secondary metabolite biosynthesis, motility, and bioluminescence by exporting signaling molecules like stilbenes.
