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

Enhancement of Consolidated Bioprocessing for Bioethanol Conversion From Water Hyacinth Using the Wild and Mutant Bacterial Strains

International Journal of Chemical Engineering, Volume 2025, Issue 1, 2025.
Bacterial strains Hangateiclostridium thermocellum KSMK1203 and Lachnoclostridium phytofermentans KSM 1203 were subjected to physiochemical mutagenesis to improve their capacity for cellulose degradation, boost ethanol production, and enhance their resilience against various substrates and byproducts.

Molecular dynamics modelling of the cellulosome multi-enzyme complex

, 2018
The conversion of cellulosic biomass into biofuels requires degradation of the biomass into fermentable sugars. The most efficient natural cellulase system for carrying out this conversion is an extracellular multi-enzymatic complex named the ...

Deconstruction of Lignocellulose into Soluble Sugars by Native and Designer Cellulosomes

mBio, 2012
Lignocellulosic biomass, the most abundant polymer on Earth, is typically composed of three major constituents: cellulose, hemicellulose, and lignin. The crystallinity of cellulose, hydrophobicity of lignin, and encapsulation of cellulose by the lignin ...

GASdb: a large-scale and comparative exploration database of glycosyl hydrolysis systems

BMC Microbiology, 2010
Background The genomes of numerous cellulolytic organisms have been recently sequenced or in the pipeline of being sequenced. Analyses of these genomes as well as the recently sequenced metagenomes in a systematic manner could possibly lead to ...

Diverse specificity of cellulosome attachment to the bacterial cell surface [PDF]

During the course of evolution, the cellulosome, one of Nature\u27s most intricate multi-enzyme complexes, has been continuously fine-tuned to efficiently deconstruct recalcitrant carbohydrates.

Expression, purification and subunit-binding properties of cohesins 2 and 3 of the Clostridium thermocellum cellulosome

, 1995
The enzymatic subunits of the cellulosome of Clostridium thermocellum are integrated into the complex by a major non-catalytic polypeptide, called scaffoldin.

Higher order scaffoldin assembly in Ruminococcus flavefaciens cellulosome is coordinated by a discrete cohesin-dockerin interaction

Scientific Reports, 2018
Cellulosomes are highly sophisticated molecular nanomachines that participate in the deconstruction of complex polysaccharides, notably cellulose and hemicellulose.

Characterization of a Double Dockerin from the Cellulosome of the Anaerobic Fungus Piromyces equi

, 2007
The assembly into supramolecular complexes of proteins having complementary activities is central to cellular function. One such complex of considerable biological and industrial significance is the plant cell wall-degrading apparatus of anaerobic ...
