“…In agreement, previous studies have shown that LSHF hydrothermal fluids contain a high concentration of methane (Charlou et al, 2000;Rommevaux et al, 2019), which could sustain the presence of methanotrophic microorganisms. Furthermore, quite abundant bacterial ASVs were related to Sulfurimonas sediminis (Campylobacterota), an hydrogen-and sulphur-oxidizing bacterium (Wang et al, 2021) or to Thiogranum longum (Gammaproteobacteria), a bacterium growing by oxidizing inorganic sulphur compounds (Mori et al, 2015). Some archaeal ASVs were related to Aciduliprofundum boonei (Thermoplasmatota), which can reduce elemental sulphur (Reysenbach et al, 2006).…”

In hydrothermal environments, diffuse fluids emanations provide optimal conditions for the development of iron-rich microbial mats. Here, we present a unique spatial and temporal study of phylogenetic and chemical data from this type of mats and their associated hydrothermal fluids from two sites of the Lucky Strike Hydrothermal Field (EMSO-Azores deep-sea observatory), collected annually from 2016 to 2020. Our metabarcoding analyses reveal a completely different microbial community at each site, linked to the distinctive chemical composition of the diffuse fluids nourishing the mats. Capelinhos site is dominated by microorganisms with metabolisms related to iron, methane, and reduced sulphur compounds, coming from hydrothermal fluids, while North Tour Eiffel site presents higher abundances of microorganisms with metabolisms related to nitrogen, organic and oxidized sulphur compounds, coming from seawater. We present for the first time the yearly evolution of these mats over a five-year period. This analysis reveals similar variations of the microbial communities over time at both sites, indicating a regional Lucky Strike influence on the temporal scale. We also highlight more diversified microbial communities at both sites in 2016, pointing out the occurrence of a geological event that could have affected them during this specific year. Except for this year, our study shows that the communities of iron-rich microbial mats remain stable over time at both sites.

“…It was originally proposed after the isolation of Sulfurimonas autotrophica from sediments collected at a deep-sea hydrothermal vent 1 . Since then, 12 distinct Sulfurimonas species have been isolated from oxygen-deficient environments [2][3][4][5][6][7][8][9][10][11] . Bassed on 16S rRNA gene sequences, this mesophilic and chemolithoautotrophic bacterial genus is ubiquitous and a dominant member of microbial communities inhabiting redoxcline environments 12 , i n c l uding s u l fi dic e nv ir on ments a t d ee p-sea h yd ro th ermal v en ts 13-1 7 .…”

A hydrogenotrophic Sulfurimonas is globally abundant in deep-sea oxygen-saturated hydrothermal plumes

et al. 2023

Members of the bacterial genus Sulfurimonas (phylum Campylobacterota) dominate microbial communities in marine redoxclines and are important for sulfur and nitrogen cycling. Here we used metagenomics and metabolic analyses to characterize a Sulfurimonas from the Gakkel Ridge in the Central Arctic Ocean and Southwest Indian Ridge, showing that this species is ubiquitous in non-buoyant hydrothermal plumes at Mid Ocean Ridges across the global ocean. One Sulfurimonas species, USulfurimonas pluma, was found to be globally abundant and active in cold (<0−4 °C), oxygen-saturated and hydrogen-rich hydrothermal plumes. Compared with other Sulfurimonas species, US. pluma has a reduced genome (>17%) and genomic signatures of an aerobic chemolithotrophic metabolism using hydrogen as an energy source, including acquisition of A2-type oxidase and loss of nitrate and nitrite reductases. The dominance and unique niche of US. pluma in hydrothermal plumes suggest an unappreciated biogeochemical role for Sulfurimonas in the deep ocean.

“…The question of heterotypic synonymy for S. sediminis S2‐6 and S. hydrogeniphila might also arise. Indeed, they share similar genome wide identity (94% AAI, 92% ANI) and 16S rRNA genes that are 99.3% identical (Table S7) along with many shared biochemical and physiological features (Wang, Jiang, et al., 2021; Wang, Shao, et al., 2021).…”

“…In most anaerobic sub‐surface systems, the dominant chemolithotrophic SOBs belong to the co‐occurring Sulfurovum, Sulfuricurvum and Sulfurimonas ‐related species ( Campylobacteria formely Epsilonproteobacteria ). Sulfurimonas representatives thrive in a broad spectrum of environments (Han & Perner, 2015) including pelagic redox zones (Grote et al., 2012; Hamilton et al., 2014; Henkel et al., 2021; Salmaso, 2019), hydrothermal vents (Hu et al., 2021; Sikorski et al., 2010; Takai et al., 2006; Wang, Jiang, et al., 2021; Wang, Shao, et al., 2021), petroleum reservoirs (Lahme et al., 2019; Tian et al., 2017), groundwaters (Anantharaman et al., 2016; Probst et al., 2018) and mud volcanoes (Ratnikova et al., 2020). They are particularly abundant in oxygen minimum zones (15%–30% of all microorganisms (Callbeck et al., 2021; van Vliet et al., 2021)) and deep‐sea hydrothermal vents (up to 70% of all microorganisms (Campbell et al., 2006; Han & Perner, 2015; Wang et al., 2017)).…”

The permanently anoxic waters in meromictic lakes create suitable niches for the growth of bacteria using sulphur metabolisms like sulphur oxidation. In Lake Pavin, the anoxic water mass hosts an active cryptic sulphur cycle that interacts narrowly with iron cycling, however the metabolisms of the microorganisms involved are poorly known. Here we combined metagenomics, single‐cell genomics, and pan‐genomics to further expand our understanding of the bacteria and the corresponding metabolisms involved in sulphur oxidation in this ferruginous sulphide‐ and sulphate‐poor meromictic lake. We highlighted two new species within the genus Sulfurimonas that belong to a novel clade of chemotrophic sulphur oxidisers exclusive to freshwaters. We moreover conclude that this genus holds a key‐role not only in limiting sulphide accumulation in the upper part of the anoxic layer but also constraining carbon, phosphate and iron cycling.
