S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Efficacy of Ccombody as an Immunoprophylaxis Strategy: Impact on Immune Gene Expression of Pacific White Shrimp (Penaeus vannamei) Against Acute Hepatopancreatic Necrosis Disease (AHPND)

Journal of Fish Diseases, EarlyView.
ABSTRACT Acute hepatopancreatic necrosis disease (AHPND) is caused by a plasmid bearing strain of Vibrio parahaemolyticus (VpAHPND), which produces PirA and PirB toxins that specifically target and damage hepatopancreatic and epithelial cells of the shrimp gastrointestinal tract.

First Report of Tenacibaculum maritimum Infection in Grouper (Epinephelus spp.) Aquaculture in Taiwan

Journal of Fish Diseases, EarlyView.
ABSTRACT Between April 2024 and 2025, six independent outbreaks of ulcerative skin disease occurred in cultured groupers (Epinephelus spp.) across southern Taiwan and Penghu County during winter‐to‐spring seasonal transitions at water temperatures ranging from 19°C to 24°C.

Characterization of the Proteolytic Activity of a Halophilic Aspergillus reticulatus Strain SK1-1 Isolated from a Solar Saltern

Microorganisms, 2021
Salterns are hypersaline environments that are inhabited by diverse halophilic microorganisms, including fungi. In this study, we isolated a fungal strain SK1-1 from a saltern in the Republic of Korea, which was identified as Asperillus reticulatus. This

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...

Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...
