This study shows that bacterial fermentation, not respiration, dominates in upland soils during hypoxia, challenging the assumption that respiration is the primary metabolic strategy.

This study reveals how Mycobacterium smegmatis adapts to hypoxia by combining fermentative hydrogen production with carbon storage through lipid droplets.

This study identifies aridity as the primary driver of microbial community structure and biogeochemical activities in deserts across seven continents.

This study investigates microbial colonization in glacial forelands, finding that metabolically flexible bacteria drive early succession and create hospitable conditions for later colonizers.

The paper identifies Flavobacteria in coastal sediments that reduce nitrous oxide emissions by having low substrate affinity, contradicting prior assumptions and suggesting they buffer nitrogen cycling.

This study identifies aerotrophy as a primary energy source in caves, revealing microbial use of atmospheric trace gases for continuous primary production.

The paper shows bark-associated diazotrophs fix significant nitrogen in forests, contributing up to 3.8 Tg N yr-1 globally.

The paper shows that aerotolerant methanogens in oxygenated marine sediments produce methane using seaweed and seagrass metabolites, linking eutrophication to increased methane emissions.

This study shows that chemosynthesis significantly contributes to carbon fixation in microbialite ecosystems, enhancing their productivity beyond photosynthesis.
