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

Biotechnology 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.

A comprehensive census of microbial diversity in hot springs of Tengchong, Yunnan Province China using 16S rRNA gene pyrosequencing. [PDF]

PLoS ONE, 2013
The Rehai and Ruidian geothermal fields, located in Tengchong County, Yunnan Province, China, host a variety of geochemically distinct hot springs. In this study, we report a comprehensive, cultivation-independent census of microbial communities in 37 ...

Iron Sulfides Produced by Thermococcales: An Iron Detoxification Mechanism

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Thermococcales, archaea from hydrothermal vents, promote iron sulfide precipitation, enabling survival in iron‐rich environments. Some cells become encrusted in pyrite and do not survive mineralization, while surviving cells activate metal detoxification genes. This biomineralization process allows the population to withstand toxic iron concentrations,

Comparative genomic analysis reveals 2-oxoacid dehydrogenase complex lipoylation correlation with aerobiosis in archaea. [PDF]

PLoS ONE, 2014
Metagenomic analyses have advanced our understanding of ecological microbial diversity, but to what extent can metagenomic data be used to predict the metabolic capacity of difficult-to-study organisms and their abiotic environmental interactions?

Distinct Patterns of Antibiotic Sensitivities in Ammonia‐Oxidising Archaea

Environmental Microbiology, Volume 27, Issue 3, March 2025.
Antibiotic sensitivity varies between different strains of ammonia‐oxidising archaea. The results of this study will be useful for selective enrichment and development of a genetic system for ammonia‐oxidising archaea. ABSTRACT Ammonia‐oxidising archaea (AOA) are important microorganisms contributing towards the nitrogen flux in the environment. Unlike

Metagenomes from high-temperature chemotrophic systems reveal geochemical controls on microbial community structure and function. [PDF]

PLoS ONE, 2010
The Yellowstone caldera contains the most numerous and diverse geothermal systems on Earth, yielding an extensive array of unique high-temperature environments that host a variety of deeply-rooted and understudied Archaea, Bacteria and Eukarya.

Chromatin and gene regulation in archaea

Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Transcriptional and translational dynamics underlying heat shock response in the thermophilic crenarchaeon Sulfolobus acidocaldarius

mBio, 2023
High-temperature stress is critical for all organisms and induces a profound cellular response. For Crenarchaeota, little information is available on how heat shock affects cellular processes and on how this response is regulated.
