Single-cell analysis reveals an active and heterotrophic microbiome in the Guaymas Basin deep subsurface with significant heterotrophic inorganic carbon fixation

The paper uses single-cell analysis to show that most subsurface microbes in the Guaymas Basin are active and heterotrophic, with inorganic carbon fixation contributing 5% to their biomass.

Abundant and metabolically flexible lineages within the SAR324 and gammaproteobacteria dominate the potential for rubisco-mediated carbon fixation in the dark ocean

The paper analyzes metagenomic data to show that rubisco-encoding organisms, particularly from SAR324 and gammaproteobacteria, dominate carbon fixation potential in the dark ocean.

Mcr-dependent methanogenesis in Archaeoglobaceae enriched from a terrestrial hot spring

This study identifies a novel Mcr-dependent methanogenesis pathway in Methanoproducendum nevadense, enriched from a hot spring, and suggests its potential role in methane production in hydrothermal environments.
