Hydrogen sulfide production distinguishes Salmonella from close relatives, but its biological significance remains obscure. This study uncovers the secret: Salmonella uses hydrogen sulfide production as a weapon to outcompete E. coli and gain a foothold in the gut.

Microbes that oxidize toxic sulfide while reducing iron minerals have been identified as key drivers of sulfide detoxification in oxygen-free environments, accelerating this process beyond chemical reactions. doi.org/g9zqq2
Bacteria that 'breathe' iron minerals while detoxifying sulfide outpace chemical reactions
An international team of scientists led by microbiologists Marc Mussmann and Alexander Loy from the University of Vienna has discovered a new microbial metabolism: so-called MISO bacteria "breathe" iron minerals by oxidizing toxic sulfide.
