Isolation and Complete Genome Sequence of Algibacter alginolytica sp. nov., a Novel Seaweed-Degrading Bacteroidetes Bacterium with Diverse Putative Polysaccharide Utilization Loci. [PDF]

Appl Environ Microbiol, 2016
ABSTRACT The members of the phylum Bacteroidetes are recognized as some of the most important specialists for the degradation of polysaccharides. However, in contrast to research on Bacteroidetes in the human gut, research on polysaccharide degradation by marine ...

Polysaccharide utilization loci in Bacteroides determine population fitness and community-level interactions [PDF]

, 2021
Polysaccharide utilization loci (PULs) in the human gut microbiome have critical roles in shaping human health and ecological dynamics. We develop a CRISPR-FnCpf1-RecT genome-editing tool to study 23 PULs in the highly abundant species B. uniformis (BU).

Characterization of two novel species of the genus Flagellimonas reveals the key role of vertical inheritance in the evolution of alginate utilization loci [PDF]

Microbiology Spectrum
Flavobacteriaceae is the major participant in the degradation of algal polysaccharides. With diverse polysaccharide utilization loci (PULs) and specific carbohydrate-active enzymes (CAZymes), Flavobacteriaceae strains appear to have different abilities ...

Effects of diet on resource utilization by a model human gut microbiota containing Bacteroides cellulosilyticus WH2, a symbiont with an extensive glycobiome. [PDF]

PLoS Biology, 2013
The human gut microbiota is an important metabolic organ, yet little is known about how its individual species interact, establish dominant positions, and respond to changes in environmental factors such as diet.

Revisiting Hyaluronan Catabolism in Bacteroides: Pathway Conservation, Overlooked Proteins, and Predictive Accuracy [PDF]

MicrobiologyOpen
The ability of gut microbes to degrade host‐ and diet‐derived glycans is central to microbiome ecology and host interactions, yet predicting these functions in silico remains challenging.

Novel xylan degrading enzymes from polysaccharide utilizing loci of Prevotella copri DSM18205 [PDF]

Glycobiology, 2021
Abstract Prevotella copri is a bacterium that can be found in the human gastrointestinal tract. The role of P. copri in the GIT is unclear, and elevated numbers of the microbe have been reported both in dietary fiber-induced improvement in glucose metabolism but also in conjunction with certain inflammatory conditions.

Host-driven evolution shapes the polysaccharide utilization profiles of alga-associated Flavobacteriaceae [PDF]

Microbiome
Background Marine algae represent major producers of complex polysaccharides and serve as hosts for diverse microbial communities in the phycosphere. Flavobacteriaceae are among the key bacterial taxa involved in polysaccharide degradation and carbon ...

Sift-PULs: A public repository for specific functional polysaccharide utilization loci [PDF]

, 2021
AbstractBackgroundPolysaccharide utilization loci (PULs) were bacterial gene clusters encoding genes responsible for polysaccharide utilization process. PUL studies are blooming in recent years but the biochemical characterization speed is relative slow.
