Evidence of microbial activity from a shallow water whale fall (Voghera, northern Italy) [PDF]

, 2012
The fossil bones, associated carbonate cements and enclosing concretion of a Miocene mysticete from inner shelf deposits (Monte Vallassa Formation, northern Italy) were analyzed for evidence of microbial activity. Optical and scanning electron microscopy,

Stable Carbon Isotope Values of Bacteria‐Specific Fatty Acids to Assess the Reactivity of Sedimentary Organic Matter in the St. Lawrence Estuary and Gulf

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Coastal systems have seen increasing pressure from anthropogenic activities since the beginning of the century, affecting the health of these ecosystems. This increased pressure takes the form of an increase discharge of terrestrial organic matter (OM) and nutrients, leading to a higher primary productivity in the surface waters and to higher ...

Model based analysis of the methane seeping influence on the acidification in the East Siberian Arctic Shelf waters

Frontiers in Marine Science
A giant Arctic subsea permafrost reservoir of methane (CH4) in different forms (hydrates, free gas) is leaking, likely at an increasing rate under climate warming. This is causing a massive CH4 release from sediments into the water column and atmosphere.

Genomic reconstruction of an uncultured hydrothermal vent gammaproteobacterial methanotroph (family Methylothermaceae) indicates multiple adaptations to oxygen limitation

Frontiers in Microbiology, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Draft genome sequence of Methyloferula stellata AR4, an obligate methanotroph possessing only a soluble methane monooxygenase [PDF]

, 2015
Methyloferula stellata AR4 is an aerobic acidophilic methanotroph, which, in contrast to most known methanotrophs but similar to Methylocella spp., possesses only a soluble methane monooxygenase. However, it differs from Methylocella spp.

Exploring the Potential and Evaluating Hydrocarbon Degradation by Novel Antarctic Dietzia and Pusillimonas Isolates From a Pristine Environment

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
The Antarctic Dietzia and Pusillimonas isolates were tested for bioremediation applications. Genomic analyses revealed the potential to degrade complex organic compounds, potential virulence factors and resistance genes. Physiological assays showed a wide range of adaptation to abiotic factors and sensitivity to different groups of antibiotics ...

Novel Methanotrophs of the Family Methylococcaceae from Different Geographical Regions and Habitats [PDF]

, 2015
Terrestrial methane seeps and rice paddy fields are important ecosystems in the methane cycle. Methanotrophic bacteria in these ecosystems play a key role in reducing methane emission into the atmosphere.

The Role of Soil Microorganisms in Microplastic Biodegradation: Mechanisms, Carbon Preferences, and Ecological Impacts

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This work explores the complex relationship between soil carbon availability and microplastic biodegradation, highlighting competition and symbiosis among microorganisms, the repurposing of microplastic‐derived polymers, and the impact of soil organic carbon on microbial substrate preferences and carbon use efficiency variability.

Soil Organic Matter and its Stability in Aerobic and Anaerobic Conditions

Soil and Water Research, 2006
In eight samples of organic and organomineral surface horizons we studied the stability of soil organic matter in aerobic and anaerobic conditions expressed by the rate constant of its biochemical oxidation, total biochemical oxygen demand, substrate ...
