Asymmetry of nucleotide substitutions in tRNAs indicates common descent of modern organisms from a thermophilic ancestor [PDF]

open access: yesВавиловский журнал генетики и селекции
The nature of the last universal common ancestor (LUCA) of all living organisms remains a controversial issue in biology. There is evidence of both thermophilic and mesophilic LUCA origin.

Temporal dynamics of geothermal microbial communities in Aotearoa-New Zealand

open access: yesFrontiers in Microbiology, 2023
Microbial biogeography studies, in particular for geothermal-associated habitats, have focused on spatial patterns and/or individual sites, which have limited ability to describe the dynamics of ecosystem behaviour.

DNA repair enzymes of the Antarctic Dry Valley metagenome

open access: yesFrontiers in Microbiology, 2023
Microbiota inhabiting the Dry Valleys of Antarctica are subjected to multiple stressors that can damage deoxyribonucleic acid (DNA) such as desiccation, high ultraviolet light (UV) and multiple freeze-thaw cycles.

Anaerobic Thermophiles [PDF]

open access: yesLife, 2014
The term “extremophile” was introduced to describe any organism capable of living and growing under extreme conditions. With the further development of studies on microbial ecology and taxonomy, a variety of “extreme” environments have been found and an increasing number of extremophiles are being described. Extremophiles have also been investigated as

Thermophilic Hydrocarbon-Utilizing Bacilli from Marine Shallow Hydrothermal Vents as Producers of Biosurfactants

open access: yesJournal of Marine Science and Engineering, 2022
The exploitation of thermophilic hydrocarbon-utilizing bacilli could provide novel environmentally friendly surfactants. In this work, 80 thermophilic bacilli isolated from shallow hydrothermal vents of the Eolian Islands (Italy) were screened for their ...

Genetic Potential of Dissulfurimicrobium hydrothermale, an Obligate Sulfur-Disproportionating Thermophilic Microorganism

open access: yesMicroorganisms, 2021
The biochemical pathways of anaerobic sulfur disproportionation are only partially deciphered, and the mechanisms involved in the first step of S0-disproportionation remain unknown.

Potential for the anaerobic oxidation of benzene and naphthalene in thermophilic microorganisms from the Guaymas Basin

open access: yesFrontiers in Microbiology, 2023
Unsubstituted aromatic hydrocarbons (UAHs) are recalcitrant molecules abundant in crude oil, which is accumulated in subsurface reservoirs and occasionally enters the marine environment through natural seepage or human-caused spillage.
