Physiological and comparative proteomic characterization of Desulfolithobacter dissulfuricans gen. nov., sp. nov., a novel mesophilic, sulfur-disproportionating chemolithoautotroph from a deep-sea hydrothermal vent [PDF]

Frontiers in Microbiology, 2022
In deep-sea hydrothermal environments, inorganic sulfur compounds are important energy substrates for sulfur-oxidizing, -reducing, and -disproportionating microorganisms.

Unusual regulation of the CO2 concentrating mechanism of marine chemolithoautotroph Thiomicrospira pelophila [PDF]

Applied and Environmental Microbiology
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 ...

Prokaryotic Life Associated with Coal-Fire Gas Vents Revealed by Metagenomics [PDF]

Biology, 2023
The natural combustion of underground coal seams leads to the formation of gas, which contains molecular hydrogen and carbon monoxide. In places where hot coal gases are released to the surface, specific thermal ecosystems are formed. Here, 16S rRNA gene

Simultaneous sulfide and methane oxidation by an extremophile [PDF]

Nature Communications, 2023
Hydrogen sulfide (H2S) and methane (CH4) are produced in anoxic environments through sulfate reduction and organic matter decomposition. Both gases diffuse upwards into oxic zones where aerobic methanotrophs mitigate CH4 emissions by oxidizing this ...

Response to Nutrient Stress in the Industrial Model Bacterium Cupriavidus necator: A Thermal Proteome Profiling (TPP) Investigation. [PDF]

Proteomics
ABSTRACT The facultative chemolithoautotroph Cupriavidus necator is capable of heterotrophic growth on diverse carbon sources, or of autotrophic growth using CO2 fixation with H2 as an energy source. Under stress conditions, it produces biodegradable polyesters (polyhydroxyalkanoates, PHAs) as a storage material occupying a high proportion of the total

Thiomicrorhabdus marina sp.nov., an obligate chemolithoautotroph isolated from tidal zone sediment, and genome insight into the genus Thiomicrorhabdus

Frontiers in Marine Science, 2023
The contribution of microbes to the marine sulfur cycle has received considerable attention in recent years. In this study, a new Gram-stain-negative, aerobic sulfur-oxidizing bacterium, designated strain 6S2-11T, was isolated from tidal zone sediment of

Protein allocation and utilization in the versatile chemolithoautotroph Cupriavidus necator [PDF]

eLife, 2021
Bacteria must balance the different needs for substrate assimilation, growth functions, and resilience in order to thrive in their environment. Of all cellular macromolecules, the bacterial proteome is by far the most important resource and its size is ...

Isopropanol production from carbon dioxide by Cupriavidus necator using a zero-gap cell with culture broth as catholyte [PDF]

iScience
Summary: Microbial CO2 fixation is a promising route for sustainable chemical production. The facultative chemolithoautotroph Cupriavidus necator can convert CO2 into value-added compounds using H2 and O2.

Genomic characterization of SNW-1, a novel prophage of the deep-sea vent chemolithoautotroph Sulfurimonas indica NW79 [PDF]

Genetics and Molecular Biology
The globally widespread genus Sulfurimonas are playing important roles in different habitats, including the deep-sea hydrothermal vents. However, phages infecting Sulfurimonas have never been isolated and characterized to date.
