Functional exploration of in vivo and in vitro lignocellulose-fed rumen bacterial microbiomes reveals novel enzymes involved in polysaccharide breakdown

The paper identifies novel enzymes from rumen microbiomes that break down plant cell walls using a high-throughput metagenomic approach.

Within-Arctic horizontal gene transfer as a driver of convergent evolution in distantly related microalgae

The paper identifies horizontal gene transfer as a driver of convergent evolution in Arctic microalgae, highlighting ice-binding domain gene transfers between distantly related species.

The Food Additive Xanthan Gum Drives Adaptation of the Human Gut Microbiota

This study shows that xanthan gum, a common food additive, promotes the adaptation of the human gut microbiota by enabling a novel degradation pathway in an uncultured Ruminococcaceae bacterium and facilitating cross-feeding by Bacteroides species.

Microbiota-directed fibre activates both targeted and secondary metabolic shifts in the distal gut.

This study shows that a tailored acetylated galactoglucomannan fibre selectively activates butyrate-producing gut bacteria and triggers secondary metabolic shifts in neighboring microbial populations in pigs.

Proteome specialization of anaerobic fungi during ruminal degradation of recalcitrant plant fiber

This study identifies fungal-specific carbohydrate-active enzymes involved in rumen fiber degradation, highlighting their role in complementing bacterial cellulolytic activity.

A catalog of microbial genes from the bovine rumen unveils a specialized and diverse biomass-degrading environment

The paper creates a gene catalog of bovine rumen microbes, revealing high diversity and function in plant biomass degradation and methane production.
