Nitrogen cycling activities during decreased stratification in the coastal oxygen minimum zone off Namibia

The paper investigates nitrogen cycling in the Namibian coastal oxygen minimum zone under decreased stratification, identifying key microbial taxa and metabolic activities involved in nitrogen transformations.

Genome evolution in bacteria isolated from million-year-old subseafloor sediments

This study examines genome evolution in Thalassospira bacteria from million-year-old subseafloor sediments, finding reduced recombination, increased pseudogenes, and genetic drift as dominant evolutionary forces.

Anaerobic metabolism of Foraminifera thriving below the seafloor

This study investigates the metabolic adaptations of Foraminifera in anoxic marine sediments using metatranscriptomics, revealing fermentation, nitrate reduction, and phagocytic mechanisms that enable their survival and proliferation.

Chloroflexi persisting for millions of years in oxic and anoxic deep-sea clay

This study examines Chloroflexi in deep-sea sediments, showing their activity and metabolism differ between oxic and anoxic conditions over millions of years.

Lokiarchaeon exhibits homoacetogenesis

This paper shows Lokiarchaeon exhibits homoacetogenesis by coupling fermentative H2 production with the Wood-Ljungdahl pathway under anoxic conditions.
