Temporal response patterns of human gut microbiota to dietary fiber

iMeta, EarlyView.
In this study, 19 overweight participants, with or without type 2 diabetes mellitus, underwent 14 days of normal‐diet observation followed by 14 days of dietary fiber intervention. Fecal samples and continuous glucose monitoring data were collected daily throughout the 28‐day period.

Stability of the human faecal microbiome in a cohort of adult men [PDF]

, 2018
Characterizing the stability of the gut microbiome is important to exploit it as a therapeutic target and diagnostic biomarker. We metagenomically and metatranscriptomically sequenced the faecal microbiomes of 308 participants in the Health Professionals

Spatio‐temporal characteristics of the gastrointestinal resistome in a cow‐to‐calf model and its environmental dissemination in a dairy production system

iMeta, EarlyView.
This study revealed spatio‐temporal characteristics of gastrointestinal resistome in a cow‐to‐calf model and the pattern of their spread to the environment and offspring in the dairy production system. The gastrointestinal tract of dairy cows is a natural reservoir of resistomes and distinguished by gut sites and regions.

Perturbation of the Human Microbiome as a Contributor to Inflammatory Bowel Disease

Pathogens, 2014
The human microbiome consist of the composite genome of native flora that have evolved with humanity over millennia and which contains 150-fold more genes than the human genome.

Metagenomics in CO2 Monitoring

Energy Procedia, 2013
AbstractLeakage from CO2 storage areas is likely to affect the microbial communities in the overlaying sediments. We have conducted a baseline characterization of the microbial communities present in the surface sediments overlaying the Johansen formation, a potential site for CO2 storage, using metagenomics.

Ecogenomics and limnological dynamics of a new Thiocapsa species blooming in the whole water column of a karstic lake

Limnology and Oceanography, EarlyView.
Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Microbial β-Glucosidase: sources, production and applications [PDF]

, 2017
Cellulose is the most abundant biopolymer in biosphere and the major constituent of plant biomass. Cellulose polymer is made up of β-glucose units linked by β-glucosidic bonds. Cellulase is an enzymatic system that catalyzes the hydrolysis of cellulose

Seasonal and spatial transitions in phytoplankton assemblages spanning estuarine to open ocean waters of the tropical Pacific

Limnology and Oceanography, EarlyView.
Abstract Islands in the tropical Pacific supply elevated nutrients to nearshore waters that enhance phytoplankton biomass and create hotspots of productivity in otherwise nutrient‐poor oceans. Despite the importance of these hotspots in supporting nearshore food webs, the spatial and temporal variability of phytoplankton enhancement and changes in the ...

Heterogeneity of Intratumoral Microbiota Within the Tumor Microenvironment and Relationship to Tumor Development

Med Research, EarlyView.
Mutual shaping of tumor microbiota and TME. Intratumoral microbiota—comprising diverse bacteria, fungi, viruses, and intracellular organisms—play critical and dynamic roles in shaping the tumor microenvironment (TME). Their spatial and compositional diversity contributes to both intratumoral and intertumoral heterogeneity, influencing immune modulation

Large Quantities of Bacterial DNA and Protein in Common Dietary Protein Source Used in Microbiome Studies

PROTEOMICS, EarlyView.
ABSTRACT Diet has been shown to greatly impact the intestinal microbiota. To understand the role of individual dietary components, defined diets with purified components are frequently used in diet‐microbiota studies. Defined diets frequently use purified casein as the protein source.
