Maternal and infant gut microbiome

open access: yesiMeta, Volume 5, Issue 4, August 2026.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

Metagenomic evidence clarifies the texture-dependent cascading effects of organic degradation on soil hypoxia and N2O emission

open access: yesFrontiers in Microbiology
IntroductionSoil pore-scale aeration is a crucial yet often overlooked factor influencing the effectiveness of nitrous oxide (N2O) emission mitigation strategies.

How obligatory is anaerobiosis? [PDF]

open access: yesMolecular Microbiology, 2008
SummaryHistorically many bacteria have been classified as obligate anaerobes. They have been construed as wholly intolerant of oxygen, a feature that was originally ascribed to their lack of superoxide dismutases and catalases. Clostridial species were regarded as classic examples.

Crystal Structure of the Active Site Mutant Form of Soluble Fumarate Reductase, Osm1

open access: yesCrystals, 2019
Soluble fumarate reductase is essential for survival under anaerobic conditions. This enzyme can maintain the redox balance in the cell by catalyzing the reduction of fumarate to succinate.

Simulating soil organic carbon and greenhouse gas emissions in dry regions: A review of the scope and limitations of biogeochemical models

open access: yesAgronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Soil organic carbon (SOC) dynamics and greenhouse gas (GHG) emissions in dry (arid and semi‐arid) agroecosystems are regulated by low and variable moisture, episodic wet–dry cycles, and limited organic inputs. Although process‐based biogeochemical models are widely used to quantify these processes, a comprehensive assessment of their ...

Biomethane Energy Production Using Orange Hydrogen Coupled With CO2 Sequestration and Utilization

open access: yesCarbon Neutralization, Volume 5, Issue 4, July 2026.
In subsurface hydrocarbon‐simulated environments, injected CO2 follows dual transformation routes: geochemical mineralization into stable carbonates (CCS) and microbially mediated conversion into CH4 energy through anaerobic metabolic processes. ABSTRACT The escalating concerns of global warming have intensified the global demand for clean energy ...

A Chlamydomonas mutant locked in anaerobiosis

open access: yes, 2011
The soil dwelling microalga Chlamydomonas reinhardtii most likely encounters transient periods of anaerobiosis in its natural environment, for instance at night time or when photosynthesis is turned down in response to macronutrient limitation.

Anaerobiosis revisited: growth of Saccharomyces cerevisiae under extremely low oxygen availability [PDF]

open access: yes, 2018
The budding yeast Saccharomyces cerevisiae plays an important role in biotechnological applications, ranging from fuel ethanol to recombinant protein production. It is also a model organism for studies on cell physiology and genetic regulation.
