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.

The acetyl xylan esterase II gene from Penicillium purpurogenum is differentially expressed in several carbon sources, and tightly regulated by pH [PDF]
, 2004 http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-97602004000100011&lng=es&nrm=isoThe expression of the acetyl xylan esterase II (axeII) gene from Penicillium purpurogenum is repressed by glucose and induced by xylan, as well as to a small ...

Thermostability of β‐xylosidase from Aspergillus sydowii MG49 [PDF]
FEBS Letters, 1993 Heating of Aspergillus β‐xylosidase at 85°C ± 1°C and pH 5.5–6.0 (optimum for activity), causes irreversible, covalent thermoinactivation of the enzyme, involving oxidation of the thiol groups that are required for catalysis. Exogenous addition of cysteine, DTT, GSH and mercaptoethanol stabilizes the enzyme by extending its half‐life.

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.

Beta-xylosidase activity of a GH3 glucosidase/xylosidase from yak rumen metagenome promotes the enzymatic degradation of hemicellulosic xylans [PDF]
Letters in Applied Microbiology, 2011 To characterize the duel activities of a glycosyl hydrolase family 3 β-glucosidase/xylosidase from rumen bacterial metagenome and to investigate the capabilities of its β-d-xylosidase activities for saccharification of hemicellulosic xylans. A β-glucosidase/xylosidase gene RuBGX1 was cloned from yak (Bos grunniens) rumen using the metagenomic ...

Halorhabdus tiamatea: Proteogenomics and glycosidase activity measurements identify the first cultivated euryarchaeon from a deep-sea anoxic brine lake as potential polysaccharide degrader. [PDF]
, 2014 Euryarchaea from the genus Halorhabdus have been found in hypersaline habitats worldwide, yet are represented by only two isolates: Halorhabdus utahensis AX-2T from the shallow Great Salt Lake of Utah, and Halorhabdus tiamatea SARL4BT from the Shaban ...

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

Bioinformatic characterisation of genes encoding cell wall degrading enzymes in the Phytophthora parasitica genome [PDF]
, 2016 BACKGROUND A critical aspect of plant infection by the majority of pathogens is penetration of the plant cell wall. This process requires the production and secretion of a broad spectrum of pathogen enzymes that target and degrade the many complex ...

Thermostable ?-xylosidase from Thermomonospora curvata
Journal of Industrial Microbiology and Biotechnology, 1998 produced a thermostable β-xylosidase during growth on birch xylan. The enzyme, extracted by sonication of early stationary phase mycelia, was purified by isoelectric focusing and size exclusion HPLC. The isoelectric point was pH 4.8. The molecular weight was estimated to be 102 000 by size exclusion HPLC and 112 000 by SDS-PAGE.
