Presence of algal symbionts affects denitrifying bacterial communities in the sea anemone Aiptasia coral model

Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz

The coral-algal symbiosis is maintained by a constant and limited nitrogen availability in the holobiont. Denitrifiers, i.e., prokaryotes reducing nitrate/nitrite to dinitrogen, could contribute to maintaining the nitrogen limitation in the coral holobiont ...

High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the ‘greening’ of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, ...

Mitochondrial Creatine Kinase Attenuates Pathologic Remodeling in Heart Failure

Yi Zhang, Annina Stuber, Ashish Gupta

BACKGROUND: Abnormalities in cardiac energy metabolism occur in heart failure (HF) and contribute to contractile dysfunction, but their role, if any, in HF-related pathologic remodeling is much less established. CK (creatine kinase), the primary muscle ene ...

Conditional essentiality of a complex I-like enzyme in strict anaerobes: the case of Desulfitobacterium

Christof Holliger, Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Florence Armand

Respiratory complex I is a well-known player in aerobic respiration; it couples the transfer of two electrons from NADH to ubiquinone alongside with proton pumping. Bacterial complex I is usually composed of fourteen subunits forming three different module ...

Antimicrobial susceptibility testing by measuring bacterial oxygen consumption on an integrated platform

Martinus Gijs, Thomas Lehnert, Yang Liu

Cellular respiration is a fundamental feature of metabolic activity and oxygen consumption can be considered as a reliable indicator of bacterial aerobic respiration, including for facultative anaerobic bacteria like E. coli. Addressing the emerging global ...

Organohalide respiration in Firmicutes: energy metabolism and transcription regulation

Mathilde Stéphanie Willemin

Organohalides are a class of compounds often considered as persistent pollutants and harmful to environmental and human health. Some bacteria, among which are representatives from the Firmicutes phylum, are capable of using these compounds as terminal acce ...

Organohalide respiration: breakthrough towards the elucidation of the electron-accepting moiety of the respiratory chain

Christof Holliger, Julien Maillard, Adrian Schmid, Lorenzo Cimmino

Background Organohalide respiration (OHR) is a bacterial anaerobic process in which chlorinated compound, e.g. tetrachloroethene (PCE), is used as terminal electron acceptors. Dehalobacter restrictus PER-K23, a paradigmatic organohalide-respiring bacterium ...

2021

Short-term plant respiration (R) increases exponentially with rising temperature, but drought could reduce respiration by reducing growth and metabolism. Acclimation may alter these responses. We examined if species with different drought responses would d ...

Insights into the microbial reduction of pentavalent and hexavalent uranium species by Shewanella oneidensis MR-1

Margaux Camille Andréa Molinas

Decades of uranium-related activities such as ore mining, nuclear power generation, weapon manufacture, storage of nuclear wastes, have contributed to the release of U in the environment. U occurrence is concerning, since in surface environments, U is typi ...
