Alistipes senegalensis is Critically Involved in Gut Barrier Repair Mediated by Panax Ginseng Neutral Polysaccharides in Aged Mice

Advanced Science, EarlyView.
An integral functional axis through which GPN and functional metabolites of Alistipes senegalensis can hydrolyze tryptophan into indoles. Furthermore, the Alistipes senegalensis‐indole‐AhR pathway is found to be associated with increased expression of tight junction‐associated proteins and activation of gut stem cells.

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 ...

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.

Reverse Methanogenesis and Respiration in Methanotrophic Archaea

Archaea, 2017
Anaerobic oxidation of methane (AOM) is catalyzed by anaerobic methane-oxidizing archaea (ANME) via a reverse and modified methanogenesis pathway. Methanogens can also reverse the methanogenesis pathway to oxidize methane, but only during net methane ...

A Two‐Component Pseudo‐Icosahedral Protein Nanocompartment with Variable Shell Composition and Irregular Tiling

Advanced Science, EarlyView.
The structure and assembly principles of a two‐component encapsulin nanocompartment shell are reported. The two‐component protein compartment self‐assembles from two distinct HK97‐fold shell proteins into a pseudo‐icosahedral protein shell with variable composition and irregular tiling.

Ammonia Oxidation by the Arctic Terrestrial Thaumarchaeote Candidatus Nitrosocosmicus arcticus Is Stimulated by Increasing Temperatures

Frontiers in Microbiology, 2019
Climate change is causing arctic regions to warm disproportionally faster than those at lower latitudes, leading to alterations in carbon and nitrogen cycling, and potentially higher greenhouse gas emissions.

High proportions of bacteria and archaea across most biomes remain uncultured

The ISME Journal, 2019
A recent paper by Martiny argues that “high proportions” of bacteria in diverse Earth environments have been cultured. Here we reanalyze a portion of the data in that paper, and argue that the conclusion is based on several technical errors, most notably

A Novel nor@DHB Matrix for Direct Microbial Analysis in Lung Cancer Tissues

Advanced Science, EarlyView.
Integrated matrix‐assisted laser desorption/ionization mass spectrometry workflow quantifies intratumoral microbes in lung cancer through lipopolysaccharide/lipid A extraction from biopsies. The novel ionic matrix called norharmane conjugated to 2,5‐dihydroxybenzoic acid enhances lipid A ionization, enabling direct detection of bacterial genera ...
