Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Intratumoral Fusobacterium nucleatum Drives Cancer‐Associated Fibroblasts Enrichment and Immune Exclusion in Esophageal Squamous Cell Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
Fusobacterium nucleatum contributes to the progression of ESCC by inducing NF‐κB–mediated inflammatory signaling in tumor cells and promoting CAFs activation. Its presence may facilitate immune exclusion and tumor invasion through stromal remodeling. Furthermore, F.

Candidatus Nitrosocaldus cavascurensis, an Ammonia Oxidizing, Extremely Thermophilic Archaeon with a Highly Mobile Genome

Frontiers in Microbiology, 2018
Ammonia oxidizing archaea (AOA) of the phylum Thaumarchaeota are widespread in moderate environments but their occurrence and activity has also been demonstrated in hot springs. Here we present the first enrichment of a thermophilic representative with a

Unifying the global phylogeny and environmental distribution of ammonia-oxidising archaea based on amoA genes

Nature Communications, 2018
Ammonia-oxidising archaea (AOA) are ubiquitous and abundant in nature and play a major role in nitrogen cycling. AOA have been studied intensively based on the amoA gene (encoding ammonia monooxygenase subunit A), making it the most sequenced functional ...

Diverse Asgard archaea including the novel phylum Gerdarchaeota participate in organic matter degradation

Science China Life Sciences, 2020
Asgard is an archaeal superphylum that might hold the key to understand the origin of eukaryotes, but its diversity and ecological roles remain poorly understood.

Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Identification of novel components of the Ced and Ups systems in Saccharolobus islandicus REY15A

mLife
In Sulfolobales cells, transcription of the Ups (UV‐inducible pili of Sulfolobus) and Ced (Crenarchaeal system for exchange of DNA) genes is highly induced by DNA damage, and the two systems play key roles in pili‐mediated cell aggregation and ...

Antibiotic Sensitivity of Vibrio spp. and Shewanella algae Isolated From Brood and Egg of Mud Crab Hatchery

Animal Research and One Health, EarlyView.
Vibrio alginolyticus NBRC 15630, Vibrio parahaemolyticus ATCC 17802, Shewanella algae DW01, and Shewanella algae ATCC 51192 bacterial strains were found in the Mud crab brood and egg samples. All isolates were found to be sensitive to cefotaxime, chloramphenicol, gentamicin, and nitrofurantoin antibiotics.

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, EarlyView.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

Diel Patterns in the Composition and Activity of Planktonic Microbes in a Subtropical Bay

Ocean-Land-Atmosphere Research
Planktonic microbes play a crucial role in the matter transformation and energy transfer of marine ecosystems. Marine microbial communities are profoundly influenced by various environmental factors, and their variations are typically investigated in a ...
