TL;DR: It is demonstrated that conductive particles enable the partnership between SAO bacteria and methanogens from the coastal sediments of the Bothnian Bay of the Baltic Sea, and mineral SAO (syntrophic acetate oxidation) could be a vital pathway for CO2-reductive methanogenesis in the environment, especially in sediments rich in conductive minerals.

TL;DR: Substantial changes in microbial transcription induced by sample collection and incubation in experimental bioreactors are demonstrated, highlighting the impressive capacity for transcriptional changes within complex microbial communities.

TL;DR: In this article, anaerobic oxidation of methane coupled to denitrification (DAOM) is investigated in a simulated natural redox zonation, and the results provide the first experimental evaluation of the kinetics of DAOM in whole sediment cores and indicate that AOM can consume a substantial part of the methane flux in nitrate-rich environments.

TL;DR: The chapter reviews the ecology and phylogeny of sulfate reducers in nature and looks at the principal factors regulating the process, which focuses on the process of assimilatory sulfate reduction.

TL;DR: Biogeochemical analyses of nitrogen distributions and metabolic rates with metagenomic and metatranscriptomic analysis of summertime Shelf waters revealed a diverse microbial community, stratified over shallow (< 10 m) depth gradients, with an enrichment of ammonia-oxidizing Thaumarchaeota genes and transcripts in deeper more oxygen-depleted layers, and a comparatively low representation of sequences related to nitrite oxidation.
