Cellulosomal hemicellulases: Indispensable players for ensuring effective lignocellulose bioconversion

Green Carbon
The bioconversion of lignocellulose has attracted global attention, due to the significant potential of agricultural and forestry wastes as renewable zero-carbon resources and the urgent need for substituting fossil carbon.

Minimalistic Cellulosome of the Butanologenic Bacterium Clostridium saccharoperbutylacetonicum

mBio, 2020
Clostridium saccharoperbutylacetonicum is a mesophilic, anaerobic, butanol-producing bacterium, originally isolated from soil. It was recently reported that C. saccharoperbutylacetonicum possesses multiple cellulosomal elements and would potentially form

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.

A two-component system (XydS/R) controls the expression of genes encoding CBM6-containing proteins in response to straw in Clostridium cellulolyticum.

PLoS ONE, 2013
The composition of the cellulosomes (multi enzymatic complexes involved in the degradation of plant cell wall polysaccharides) produced by Clostridium cellulolyticum differs according to the growth substrate. In particular, the expression of a cluster of

Comparative characterization of all cellulosomal cellulases from Clostridium thermocellum reveals high diversity in endoglucanase product formation essential for complex activity

Biotechnology for Biofuels, 2017
Background Clostridium thermocellum is a paradigm for efficient cellulose degradation and a promising organism for the production of second generation biofuels. It owes its high degradation rate on cellulosic substrates to the presence of supra-molecular
