Unusual regulation of the CO2 concentrating mechanism of marine chemolithoautotroph Thiomicrospira pelophila [PDF]
Autotrophic organisms fix dissolved inorganic carbon (DIC: CO2, HCO3-, CO3-2) into biomass, introducing organic carbon into the global carbon cycle. Many lineages of autotrophs developed CO2 concentrating mechanisms (CCMs) to grapple with the catalytic ...

At deep-sea vent systems, hydrothermal emissions rich in reductive chemicals replace solar energy as fuels to support microbial carbon assimilation. Until recently, all the microbial components at vent systems have been assumed to be fostered by the ...

Comparative Genomics on Cultivated and Uncultivated Freshwater and Marine “Candidatus Manganitrophaceae” Species Implies Their Worldwide Reach in Manganese Chemolithoautotrophy [PDF]
Chemolithoautotrophic manganese oxidation has long been theorized but only recently demonstrated in a bacterial coculture. The majority member of the coculture, “Candidatus Manganitrophus noduliformans,” is a distinct but not yet isolated lineage in the ...

Chemolithotrophy in the continental deep subsurface: Sanford Underground Research Facility (SURF), USA [PDF]
The deep subsurface is an enormous repository of microbial life. However, the metabolic capabilities of these microorganisms and the degree to which they are dependent on surface processes are largely unknown. Due to the logistical difficulty of sampling

Cultivation and metabolic versatility of novel and ubiquitous chemolithoautotrophic Campylobacteria from mangrove sediments [PDF]
Chemolithoautotrophic members from the Campylobacteria class are dominant key players in sulfidic habitats, where they make up a stable portion of sulfide-oxidizing bacterial communities. Nevertheless, few isolates have so far been cultivated and studied

Diverse Sulfuriferula spp. from sulfide mineral weathering environments oxidize ferrous iron and reduced inorganic sulfur compounds [PDF]
Microorganisms are important catalysts for the oxidation of reduced inorganic sulfur compounds. One environmentally important source of reduced sulfur is metal sulfide minerals that occur in economic mineral deposits and mine waste.

Boundaries of photosynthesis: adaptations of carbon fixation in extreme environments. [PDF]
Photosynthesis faces challenges from environmental extremes of temperature, pH, and salinity, limiting gas diffusion, modifying membrane fluidity, and destabilizing photochemical and biochemical reactions. Photosynthetic organisms have evolved unique adaptations overcoming these stresses and maintaining their photosynthetic activity.

The Microbiology and Geochemistry of the Shallow-Water Hydrothermal Vents of the Gulf of Naples, Italy. [PDF]
This study investigated the interplay between fluid geochemistry and microbial diversity in the shallow‐water hydrothermal vents of the gulf of Naples, Italy. We found that hydrothermal fluid chemistry and the geological settings where the vents are hosted play a key role in shaping microbial distribution.
