Biotechnol Bioeng. 2026 Sep 6. doi: 10.1002/bit.70373. Online ahead of print. ABSTRACT 28-epi-homobrassinolide (28-epi-HBL), a bioactive analog of the steroidal phytohormone brassinolide, exhibits broad biological activities and considerable application potential. However, conventional chemical routes remain limited by tetrahydroxylation step that relies on highly toxic osmium tetroxide in combination with costly chiral ligands, whereas the Baeyer-Villiger…

Harmful Algae. 2026 Nov;159:103210. doi: 10.1016/j.hal.2026.103210. Epub 2026 Aug 29. ABSTRACT As a dormant stage of the dinoflagellate life cycle, resting cysts play crucial ecological roles, particularly for bloom-forming species, as supported by abundant evidence. They can remain viable in marine sediments for decades to centuries and directly regulate seasonal population dynamics and initiate HABs…

ABSTRACT The application of chemical dispersants in marine oil spill bioremediation remains controversial due to uncertain effects on microbial activity. This study investigated how four diverse surfactants impact n-tetradecane biodegradation by the marine hydrocarbonoclastic yeast Yarrowia lipolytica. The tested agents encompassed hydrophilic…

ABSTRACT Accurate discrimination of white tea storage years is important for quality evaluation, authenticity control, and market regulation. In this study, an HP-β-CD-functionalized hydrogel surface-enhanced Raman scattering (SERS) substrate was developed for rapid storage-year discrimination of white tea. Hydroxypropyl-β-cyclodextrin-functionalized silver nanoparticles (HP-β-CD/Ag…

ABSTRACT Enzyme immobilization is generally used to improve enzyme stability and reusability for industrial applications. In this study, a novel non-covalent immobilization strategy was developed using the SH3-like domains of alternansucrase from Leuconostoc citreum ABK-1 (LcAlts). SH3-like domains contain hydrophobic surface, suggesting…

Anal Chim Acta. 2026 Nov 1;1421:346035. doi: 10.1016/j.aca.2026.346035. Epub 2026 Jul 27. ABSTRACT Since metal-based enzyme mimics can raise biosafety concerns due to potential toxicity accumulation, it is necessary to develop metal-free alternatives that exhibit high catalytic efficiency and enhanced selectivity. Herein, we report the development of bipyridine-bridged covalent organic frameworks (COFs) exhibiting peroxidase-like (POD-like)…

ABSTRACT Laccase provides a green and eco-friendly solution for the degradation of widely used anthraquinone and triphenylmethane dyes. However, its practical application remains constrained by several obstacles, including poor stability, low redox potential, and mediator leakage, which affect both dye degradation efficiency and…
