Abstract
SummaryMicroorganisms are main drivers of the sulfur, nitrogen and carbon biogeochemical cycles. These elemental cycles are interconnected by the activity of different guilds in sediments or wastewater treatment systems. Here, we investigated a nitrate‐reducing microbial community in a laboratory‐scale bioreactor model that closely mimicked estuary or brackish sediment conditions. The bioreactor simultaneously consumed sulfide, methane and ammonium at the expense of nitrate. Ammonium oxidation o

Abstract
SummaryAs in many deep underground environments, the microbial communities in subsurface high‐CO2 ecosystems remain relatively unexplored. Recent investigations based on single‐gene assays revealed a remarkable variety of organisms from little studied phyla in Crystal Geyser (Utah, USA), a site where deeply sourced CO2‐saturated fluids are erupted at the surface. To provide genomic resolution of the metabolisms of these organisms, we used a novel metagenomic approach to recover 227 high‐quality

Endomicrobium proavitum, the first isolate of Endomicrobia class. nov. (phylum Elusimicrobia) – an ultramicrobacterium with an unusual cell cycle that fixes nitrogen with a Group IV nitrogenase

Abstract
SummaryThe bacterial tree contains many deep‐rooting clades without any cultured representatives. One such clade is ‘Endomicrobia’, a class‐level lineage in the phylum Elusimicrobia represented so far only by intracellular symbionts of termite gut flagellates. Here, we report the isolation and characterization of the first free‐living member of this clade from sterile‐filtered gut homogenate of defaunated (starch‐fed) Reticulitermes santonensis. Strain Rsa215 is a strictly anaerobic ultramicroba
