The paper investigates viral and bacterial communities in slick and non-slick sea-surface microlayers, finding distinct viral communities and metabolic profiles in slicks.

This study links sulfur metabolism in deep-sea hydrothermal plumes to microbial biogeography and biogeochemical cycling using genomic data from 37 plumes across 8 ocean basins.

This study identifies bacteria in oxic freshwater lakes that produce hydrogen sulfide through cysteine degradation, revealing a new pathway for sulfur cycling in oxygenated environments.

This study identifies 39 viral gene families involved in organosulfur metabolism across diverse ecosystems, showing their role in sulfide production and viral fitness.

The paper identifies 227 auxiliary metabolic genes in 191 phages from twelve environments, showing their role in sulfur and thiosulfate oxidation and ecological impact on biogeochemistry.

The paper characterizes novel marine Proteobacteria from hydrothermal vents using multi-omics, revealing their metabolic diversity and environmental adaptation strategies.
