This study investigates how horizontal gene transfer and selection drive microbial adaptation in Antarctic soils, finding widespread HGT of aerotrophy-related genes and strong purifying selection.

The paper shows that catabolite repression regulates hydrogen consumption in Mycobacterium smegmatis by modulating the expression of the huc operon in response to glycerol availability.

This study identifies the group B [FeFe]-hydrogenase as the primary enzyme driving fermentative H2 production in the human gut, linking it to gut health and disease.

This study shows that 3-NOP reduces methane emissions in ruminants by altering microbial communities and fermentation pathways, but limits productivity gains due to shifts in hydrogen-cycling microbes.
