A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

open access: yesBiotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Confounding effects of oxygen and temperature on the TEX 86 signature of marine Thaumarchaeota [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance Ammonia-oxidizing archaea (AOA) are among the most abundant microorganisms in the ocean. Apart from having a major influence on the nitrogen cycle, the glycerol dibiphytanyl glycerol tetraether (GDGT) membrane lipids of AOA are widely used to reconstruct past sea surface temperatures.

Microbial diversity in the deep-subsurface hydrothermal aquifer feeding the giant gypsum crystal-bearing Naica mine, Mexico

open access: yesFrontiers in Microbiology, 2013
The Naica mine in Northern Mexico is famous for its giant gypsum crystals, which may reach up to 11 m long and contain fluid inclusions that might have captured microorganisms during their formation.

Abundance, classification and genetic potential of Thaumarchaeota in metagenomes of European agricultural soils: a meta-analysis

open access: yesEnvironmental Microbiome, 2023
Background For a sustainable production of food, research on agricultural soil microbial communities is inevitable. Due to its immense complexity, soil is still some kind of black box.

Membrane interaction of cyanobacterial and chloroplast ESCRT‐III proteins

open access: yesThe Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY More than three decades ago, the inner membrane‐associated protein of 30 kDa (IM30), also known as Vipp1, was identified in pea chloroplasts to bind to the chloroplast inner envelope membrane. IM30/Vipp1 is a membrane‐associated and soluble stromal protein and is proposed to mediate vesicle formation.

Horizontal gene transfer of a chloroplast DnaJ-Fer protein to Thaumarchaeota and the evolutionary history of the DnaK chaperone system in Archaea

open access: yesBMC Evolutionary Biology, 2012
Background In 2004, we discovered an atypical protein in metagenomic data from marine thaumarchaeotal species. This protein, referred as DnaJ-Fer, is composed of a J domain fused to a Ferredoxin (Fer) domain. Surprisingly, the same protein was also found

Microbial regulation of global macroalgal blooms (green tides): From holobiont interactions to bloom dynamics and biogeochemistry

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Green tides caused by Ulva species have become one of the most serious marine ecological disasters, now impacting many coastal nations around the world. Although climatic and environmental drivers of these macroalgal blooms are well recognized, growing evidence identifies Ulva‐associated microbiota as potential pivotal regulators of bloom ...

Partitioning ofThaumarchaeotapopulations along environmental gradients in high mountain lakes [PDF]

open access: yesFEMS Microbiology Ecology, 2012
We investigated the spatial distribution and diversity of ammonia-oxidizing Archaea (AOA) across gradients of pH, trophic status and altitude in a set of high mountain lakes (Limnological Observatory of the Pyrenees, north-east Spain). Both phylogeny- and taxonomy-based approaches revealed well-defined AOA community patterns with pH as the main ...

The role of the gut microbiome in the regulation of high‐altitude adaptation

open access: yesiMeta, Volume 5, Issue 1, February 2026.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...

A hot origin of dissimilatory sulfite reduction catalyzed by DsrAB in the Paleoarchean Era

open access: yesmLife, Volume 5, Issue 1, Page 108-121, February 2026.
Abstract Dissimilatory sulfite reduction (DSR) has been essential to microbial energy metabolism in the biogeochemical sulfur cycle since the Paleoarchean Era. However, due to the lack of an integrated assessment of geological record and genomic data, the evolutionary origin of DSR remains elusive in terms of time, habitat, and genetic basis.
