Quantitative analysis of amino acid excretion by Methanothermobacter marburgensis under N2-fixing conditions

Scientific Reports
Methanogenic archaea (methanogens) possess fascinating metabolic characteristics, such as the ability to fix molecular nitrogen (N2). Methanogens are of biotechnological importance due to the ability to produce methane (CH4) from molecular hydrogen (H2 ...

Identification of XylR, the Activator of Arabinose/Xylose Inducible Regulon in Sulfolobus acidocaldarius and Its Application for Homologous Protein Expression

Frontiers in Microbiology, 2020
The thermophilic archaeon Sulfolobus acidocaldarius can use different carbon sources for growth, including the pentoses D-xylose and L-arabinose. In this study, we identified the activator XylR (saci_2116) responsible for the transcriptional regulation ...

Lipid Biology of Archaea

Archaea, 2012
Today, there is increasing awareness of the multiple dynamic roles of lipids in cell life. Knowing how lipid molecular species are organized, interact with proteins, and change with environmental stress and metabolic state is crucial to understanding the membrane structure and the cellular functions. The present view of lipid biology arises from

H2S Is a Potential Universal Reducing Agent for Prx6‐Type Peroxiredoxins

Advanced Science, EarlyView.
We report the identification of H2S as reducing agent for Prx6‐type peroxiredoxins. In contrast to common physiological reducing agents of other peroxiredoxins, HS− is small enough to access the active site of oxidized Prx6‐type enzymes in the fully‐folded protein conformation.

“Influence of plasmids, selection markers and auxotrophic mutations on Haloferax volcanii cell shape plasticity”

Frontiers in Microbiology, 2023
Haloferax volcanii and other Haloarchaea can be pleomorphic, adopting different shapes, which vary with growth stages. Several studies have shown that H.

Graphitized Biochar Derived from Agricultural Wastes Enhances Methanogenesis via Conductivity‐Driven Direct Interspecies Electron Transfer

Advanced Science, EarlyView.
This work clarifies how feedstocks and their structural features promote methanogenesis, and identifies the key regulatory factors, reducing pollution to the global environment, and also helps to alleviate the energy crisis. This is the first study to systematically link feedstock lignin content, pyrolysis conditions, biochar graphitization, and DIET ...

Electron cryo-microscopy reveals the structure of the archaeal thread filament

Nature Communications, 2022
Pili are filamentous appendages on the surface of bacteria and archaea, and play roles in multiple processes such as adhesion, motility and horizontal gene transfer. Here, Gaines et al. describe the structure of a new type of pilus, termed ‘thread’, from

Multiple Sampling Capsule Robot for Studying Gut Microbiome

Advanced Intelligent Systems, EarlyView.
A multiple sampling capsule robot (MSCR) is developed for longitudinal gut microbiome analysis. Employing electromagnetic field control, the MSCR can locomote actively, precisely align the selected channel, and collect up to six microbiome samples with minimal cross‐contamination.

Next Generation DNA-Seq and Differential RNA-Seq Allow Re-annotation of the Pyrococcus furiosus DSM 3638 Genome and Provide Insights Into Archaeal Antisense Transcription

Frontiers in Microbiology, 2019
Pyrococcus furiosus DSM 3638 is a model organism for hyperthermophilic archaea with an optimal growth temperature near 100°C. The genome was sequenced about 18 years ago.
