Food Safety and Health, EarlyView.In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Basin Scale Variation on the Composition and Diversity of Archaea in the Pacific Ocean
Frontiers in Microbiology, 2017 The Archaea are a widely distributed group of prokaryotes that inhabit and thrive in many different environments. In the sea, they play key roles in various global biogeochemical processes.

Microbial communities and functional diversity in seafood
JSFA reports, EarlyView.Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Marine archaea take a short cut in the nitrogen cycle [PDF]
Proceedings of the National Academy of Sciences, 2012 Seeing “nitrification” and “Archaea” in the title of the paper in PNAS by Alonso-Saez et al. (1) will not surprise anyone following the story about the role of these microbes in an important pathway of the nitrogen cycle. What will puzzle, if not surprise, everyone is the other key word, “urea.” That nitrogenous compound never comes up in discussions ...

Structure and specificity of novel aminopeptidase from marine sediment Archaea [PDF]
Acta Crystallographica Section A Foundations and Advances, 2014 The Earth's microbial diversity remained largely unexplored until recent developments in DNA sequencing. Novel methods enabled us to access genomic information of uncultured microbial organisms and create hypotheses about their metabolic capabilities. These predictions primarily rely on the sequence similarity between a novel protein and characterized ...

Multitrophic alpha and beta diversity of lake plankton across Canada
Oikos, EarlyView.Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

Genomic ecology of Marine Group II, the most common marine planktonic Archaea across the surface ocean [PDF]
MicrobiologyOpen, 2019 AbstractPlanktonic Archaea have been detected in all the world's oceans and are found from surface waters to the deep sea. The two most common Archaea phyla are Thaumarchaeota and Euryarchaeota. Euryarchaeota are generally more common in surface waters, but very little is known about their ecology and their potential metabolisms.

Effect of the environment on horizontal gene transfer between bacteria and archaea [PDF]
PeerJ, 2017 Background Horizontal gene transfer, the transfer and incorporation of genetic material between different species of organisms, has an important but poorly quantified role in the adaptation of microbes to their environment.

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]
, 2007 The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]
, 2019 Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.
