Reassigning the role of a mesophilic xylan hydrolysing family GH43 β-xylosidase from Bacteroides ovatus, BoExXyl43A as exo-β-1,4-xylosidase

Current Research in Biotechnology
The recombinant 40 kDa BoExXyl43A glycoside hydrolase family 43 (GH43) from bacterium Bacteroides ovatus exhibited highest specific activity (U/mg) against corn cob xylan (136.8), followed by Beechwood xylan (81.1), Carbosynth xylan (69.3), 4-O-D ...

Wildfire strengthens the relationship between soil biodiversity and ecosystem multifunctionality in subtropical forests

Functional Ecology, Volume 40, Issue 5, Page 1415-1427, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildfires are disrupting and regenerating forces in nature that affect all ecosystem components. However, the impact of wildfires on soil multitrophic biodiversity and the resulting consequences for ecosystem multifunctionality (EMF) remain poorly understood.

Beech decline reshapes fine root traits, microbial composition and soil carbon–nutrient cycling

Journal of Ecology, Volume 114, Issue 5, May 2026.
This study highlights the critical role of rhizosphere interactions in nutrient cycling and tree health. It was found that tree decline triggers cascading effects that influence fine root, microbial communities and soil enzyme activities in the rhizosphere.

Conformational determinants necessary for secretion of Paecilomyces thermophila β-1,4-xylosidase that lacks a signal peptide

AMB Express, 2018
In this study, we investigated the secretion mechanism of the hyper-secretion signal peptide-lacking β-xylosidase PtXyl43, a non-classically secreted protein, from the fungus Paecilomyces thermophila in Escherichia coli BL21(DE3).

Fecal Material of Captive Wild Animals as Source of CAZymes With Application Potential

ChemBioChem, Volume 27, Issue 8, April 2026.
With the goal to identify a novel resource of enzymes, we tested for the potential of fecal metagenomes of captive wild animals to provide CAZymes. Our data show that CAZymes profiles differed between animals with varying gut physiology and diet, and that metagenomes of captive wild animals can be considered source of diverse CAZymes including rare and

Characterization of β-glucosidase activity of a Lactiplantibacillus plantarum 6-phospho-β-glucosidase

Applied Microbiology and Biotechnology
β-Glucosidases are useful for hydrolysis of glycosidically-bound volatiles (GBV), thereby facilitating the release of aroma chemicals from the fruit matrices. In this study, 10 putative glycosyl hydrolases belonging to GH1 family from Lactiplantibacillus

Diet‐Driven Divergence in Gut Microbiota Variation Between Two Sympatric Gerbil Species

Ecology and Evolution, Volume 16, Issue 4, April 2026.
ABSTRACT Gut microbiota provide various benefits to their mammalian hosts; however, knowledge regarding interspecific differences in gut microecology remains limited. This study employed 16S rRNA sequencing combined with metagenomic functional prediction (potential functions or functional potential) to conduct a comparative analysis of the gut ...
