Methanotrophic activity and diversity of methanotrophs in volcanic-geothermal soils at Pantelleria island (Italy) [PDF]
, 2014 Volcanic and geothermal systems emit endogenous gases by widespread degassing from soils, including CH4, a greenhouse gas twenty-five times as potent as CO2.

Acta Crystallographica Section D, Volume 81, Issue 11, Page 605-620, November 2025.We have studied the copper sites in three cryogenic electron‐microscopy structures of particulate methane monooxygenase with quantum refinement. We show that the CuA, CuC and CuD sites are correctly modelled and that the CuB site is mononuclear in all structures, whereas we find no support for copper in the suggested trinuclear active site or two sites

Facultative methanotrophs are abundant at terrestrial natural gas seeps [PDF]
, 2018 Background: Natural gas contains methane and the gaseous alkanes ethane, propane and butane, which collectively influence atmospheric chemistry and cause global warming.

Integrative Zoology, Volume 20, Issue 6, Page 1294-1305, November 2025.Symbiotic gill and nonsymbiotic mantle of mussel Gigantidas haimaensis responded differently to deep‐sea sampling stress caused by acute environmental changes. Sharply increased transcription factors potentially play key roles in initiating the response of sampled deep‐sea macrobenthos to the sampling stress.

Stress resistance and C1 metabolism involved in plant colonization of a methanotroph Methylosinus sp. B4S. [PDF]
, 2013 Methanotrophs are widespread and have been isolated from various environments including the phyllosphere. In this study, we characterized the plant colonization by Methylosinus sp. B4S, an α-proteobacterial methanotroph isolated from plant leaf.

Call for Standardizing Uncaria rhynchophylla as the Sole Origin of Uncariae Ramulus cum Uncis
Phytochemical Analysis, Volume 36, Issue 7, Page 1959-1973, October 2025.ABSTRACT Background Uncariae Ramulus cum Uncis (URCU) is a widely used traditional Chinese medicine (TCM) for treating neurodegenerative disorders. The Chinese Pharmacopeia recognizes five Uncaria species as authorized botanical sources of URCU; however, there is currently no established quality control method for individual species.

Aquatic plant surface as a niche for methanotrophs
Frontiers in Microbiology, 2014 This study investigated the potential local CH4 sink in various plant parts as a boundary environment of CH4 emission and consumption. By comparing CH4 consumption activities in cultures inoculated with parts from 39 plant species, we observed ...

Origin and temporal variability of unusually low δ13C-DOC values in two High Arctic catchments [PDF]
, 2016 The stable carbon isotopic composition of dissolved organic matter (δ13C-DOC) reveals information about its source and extent of biological processing. Here we report the lowest δ13C-DOC values (−43.8‰) measured to date in surface waters.
