Diversity and strain specificity of plant cell wall degrading enzymes revealed by the draft genome of Ruminococcus flavefaciens FD-1. [PDF]

PLoS ONE, 2009
BACKGROUND:Ruminococcus flavefaciens is a predominant cellulolytic rumen bacterium, which forms a multi-enzyme cellulosome complex that could play an integral role in the ability of this bacterium to degrade plant cell wall polysaccharides.

The diversity of PET degrading enzymes: A systematic review of sequence, structure, and function

Protein Science, Volume 34, Issue 10, October 2025.
Abstract Polyethylene terephthalate (PET) is one of the most significant plastic pollutants. Unlike other plastic polymers, PET can be degraded by PET‐hydrolytic enzymes (PETases). Over the past two decades, numerous publications have reported the discovery, characterization, and engineering of PETases.

Bioactive polysaccharides and their potential health benefits in reducing the risks of metabolic syndrome: A review

Food Biomacromolecules, Volume 2, Issue 3, Page 288-314, September 2025.
Abstract Metabolic syndrome (MetS) is a complex noncommunicable condition characterized by central obesity, insulin resistance, hyperlipidemia, hypertension, and hyperglycemia. Epidemiological evidence shows that MetS affects a third of the global population; however, due to its complex pathogenesis and limited drug therapy options, the increasing ...

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

iMeta, Volume 4, Issue 4, August 2025.
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.

AlphaFold-driven structural proteomics reveals extensive cellulosome machinery in human ruminococcal symbionts

mBio
Cellulosomes are large, surface-displayed enzyme complexes that enable anaerobic bacteria to degrade recalcitrant plant polysaccharides, yet cellulosome-expressing bacteria are thought to be rare in the human gut.

Grape Stalks Valorization towards Circular Economy: A Cascade Biorefinery Strategy

ChemSusChem, Volume 18, Issue 10, May 19, 2025.
A cascade protocol for grape stalks valorization has been proposed, characterized by a multidisciplinary strategy using unconventional techniques and subcritical water as a green solvent, where physical/chemical treatments synergistically interact with biological treatments to obtain added value products from all the biomass components.

Magnetizing Biotech–Advances in (In Vivo) Magnetic Enzyme Immobilization

Engineering in Life Sciences, Volume 25, Issue 3, March 2025.
ABSTRACT Industrial biocatalysis, a multibillion dollar industry, relies on the selectivity and efficacy of enzymes for efficient chemical transformations. However, enzymes, evolutionary adapted to mild biological conditions, often struggle in industrial processes that require harsh reaction conditions, resulting in reduced stability and activity ...

Diversity and Vertical Distribution of Planctomycetota in the Water Column of the Remote North Pacific

Environmental Microbiology Reports, Volume 17, Issue 1, February 2025.
In the remote regions of the Pacific Ocean, Planctomycetota diversity predominantly occupies deeper water layers ranging from 175 to 500 m. Phylogenetic analyses have identified an entire range of previously unknown genera within this group of bacteria.

A modular enzyme with combined hemicellulose‐removing and LPMO activity increases cellulose accessibility in softwood

The FEBS Journal, Volume 292, Issue 1, Page 75-93, January 2025.
This study describes a unique bi‐catalytic enzyme that combines an oxidative activity (LPMO) acting on cellulose and a hydrolase activity (Man5) acting on mannan thus facilitating the degradation of complex, co‐polymeric plant cell walls. The enzyme works by removing the most abundant cellulose‐covering softwood hemicellulose, mannan, which then allows
