Comparative metagenomic analysis reveals mechanisms for stress response in hypoliths from extreme hyperarid deserts [PDF]

, 2016
Understanding microbial adaptation to environmental stressors is crucial for interpreting broader ecological patterns. In the most extreme hot and cold deserts, cryptic niche communities are thought to play key roles in ecosystem processes and represent ...

Gut Microbiota–Metabolism Axis Shapes the Individual Metabolic Phenotype of Different Microbiota‐Accessible Carbohydrates

Food Frontiers, EarlyView.
Specific MAC bioactivities are associated with gut biotransformation. ABSTRACT Increasing the intake of microbiota‐accessible carbohydrates (MACs) has emerged as a promising nutritional strategy for preventing metabolic diseases. However, the consistency of their beneficial effects remains unclear, hindering their optimized application.

Pulicaria incisa Infusion Modulates the Gut Microbiota and Improves Locomotor Activity and Exploratory Behavior in Aging Mice

Food Frontiers, EarlyView.
‐Pi infusion significantly improved locomotor activity and exploratory behavior in aging mice; its bioactive compounds may have direct effects on behavior, which may be accompanied by a putative indirect effect involving the gut microbiota. ‐Pi infusion consumption restored commensal Bacilli levels and caused a significant decrease in Clostridia levels

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

Food Frontiers, EarlyView.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.

A novel pathway producing dimethylsulphide in bacteria is widespread in soil environments [PDF]

, 2015
The volatile compound dimethylsulphide (DMS) is important in climate regulation, the sulphur cycle and signalling to higher organisms. Microbial catabolism of the marine osmolyte dimethylsulphoniopropionate (DMSP) is thought to be the major biological ...

Construction of Chronic Kidney Disease Mouse Model Induced by Diets With Different Adenine Content

Food Safety and Health, EarlyView.
By administering a 4 weeks adenine diet to C57BL/6J mice, we identified 0.2% adenine in purified feed as the optimal chronic kidney disease model. This model induces severe renal damage, gut dysbiosis, uremic toxin accumulation, and CKD mineral bone disorder, providing a clinically relevant platform for mechanistic and therapeutic studies.

Molecular Characterization of Plasmids Harbored by Actinomycetes Isolated From the Great Salt Plains of Oklahoma Using PFGE and Next Generation Whole Genome Sequencing

Frontiers in Microbiology, 2018
One of the unique features of actinomycetes, especially the genus Streptomyces, is the presence of linear plasmids. These range in size from 12 to 600 kb, and are often termed mega-plasmids.

Ribosomal RNA operon copy number: A trait‐informed framework to close the microbial cultivation gap

iMetaOmics, EarlyView.
The vast majority of microbes remain uncultured, constraining functional validation and limiting microbiome‐based applications. We show that ribosomal RNA operon (rrn) copy number—a stable, phylogenetically conserved genomic trait—is strongly correlated with cultivation outcomes across ecosystems.
