Frontiers in Microbiology, 2022 For Clostridium ljungdahlii, the RNF complex plays a key role for energy conversion from gaseous substrates such as hydrogen and carbon dioxide. In a previous study, a disruption of RNF-complex genes led to the loss of autotrophy, while heterotrophy was ...

Levels of autotrophy and heterotrophy in mesophotic corals near the end photic zone [PDF]
Frontiers in Marine Science, 2023 Mesophotic corals live at ~30-150 m depth and can sustain metabolic processes under light-limited conditions by enhancing autotrophy through specialized photoadaptations or increasing heterotrophic nutrient acquisition.

Metabolic Adaptations Determine the Evolutionary Trajectory of TOR Signaling in Diverse Eukaryotes [PDF]
BiomoleculesEukaryotes use diverse nutrient acquisition strategies, including autotrophy, heterotrophy, mixotrophy, and symbiosis, which shape the evolution of cell regulatory networks.

Autotrophic growth of Thermus sp. PS18 and its genomic determinants shed light on the autotrophic lifestyle and its evolution in the Thermaceae family [PDF]
Frontiers in MicrobiologyA thermophilic bacterial strain PS18 was isolated from a hot spring on Kunashir Island under aerobic autotrophic conditions and identified as Thermus brevis. Autotrophy has never been demonstrated in representatives of the Thermaceae family or the entire

Chemoautotrophy in subzero environments and the potential for cold-adapted Rubisco [PDF]
Applied and Environmental MicrobiologyThe act of fixing inorganic carbon into the biosphere is largely facilitated by one enzyme, Rubisco. Beyond well-studied plants and cyanobacteria, many bacteria use Rubisco for chemolithoautotrophy in extreme environments on Earth. Here, we characterized

Microbial Autotrophy Recorded by Carbonate Dual Clumped Isotope Disequilibrium
Geochemistry, Geophysics, GeosystemsThe proliferation of microbial carbon fixation is a key control on the evolution of the biosphere and global carbon cycle. Most records of these metabolisms in ancient rocks come from organic matter or fossils, which are not always preserved.

Limited contributions of bacteria and fungi to coral nutrition revealed by amino acid δ13C analysis [PDF]
Communications BiologyCorals often form reef ecosystems that support diverse marine life, but they are sensitive to environmental fluctuations that can affect their nutrient acquisition.
