Air pollution and its multifaceted effects on insect pollinators: A review

open access: yesEcological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.
Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

Effect of Alkali Lignin on Laccase Activity and Mycelial Biomass of Flammulina velutipes

open access: yesBioResources
The effect of alkali lignin on laccase activity and mycelial biomass of Flammulina velutipes was investigated under different fermentation temperature. The secretion of laccase by F. velutipes has certain specificity. Specifically, laccase activity could

Asymmetric Catalytic Hydrogenation toward a Value‐Added Chiral Building Block: Optically Active γ‐Butyrolactone Scaffold from Renewable and Synthetic Derived Feedstocks

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 3, January 22, 2026.
This brief compendium summarizes the most successful asymmetric hydrogenation strategies for the preparation of chiral monocyclic γ‐lactone derivatives from keto acids and keto esters, with emphasis on their relevance for large‐scale production and high enatioselectivities. This article provides a brief compendium on the production of chiral monocyclic

Enzyme-Based Logic: OR Gate with Double-Sigmoid Filter Response

open access: yes, 2012
The first realization of a biomolecular OR gate function with double-sigmoid response (sigmoid in both inputs) is reported. Two chemical inputs activate the enzymatic gate processes resulting in the output signal: chromogen oxidation, which occurs when ...

Induction of laccase in Basidiomycetes: the laccase-coding messenger.

open access: yesActa biochimica Polonica, 1979
Formation of the mRNA specific for the inducible forms of laccase was evidenced in Coriolus versicolor, Pleurotus ostreatus and Pholiota mutabilis. The half-life time of these mRNAs in the fungi species studied were, respectively, 30, 37 and 24 min. Molecular weight of the newly synthesized mRNA in Pleurotus ostreatus was about 4.5X10(5), consistently ...
