Revisiting small‐molecule fluorescent probes in food freshness detection

open access: yesSmart Molecules, EarlyView.
Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

Impact of Two High‐Fiber Dietary Transitions on Fecal Consistency and Microbiota Composition in Captive Dromedary Camels (Camelus dromedarius) With Chronic Recurrent Diarrhea: A Pilot Study

open access: yesZoo Biology, EarlyView.
High‐fiber dietary interventions reshaped the gut microbiota of captive dromedaries with chronic recurrent diarrhea, but responses varied among individuals. Despite taxonomic shifts, microbial metabolic functions remained remarkably stable, supporting the resilience of the dromedary gut ecosystem and the use of fiber‐based dietary management.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Photofermentative Hydrogen Production by Agar Immobilized Co-Cultures of Purple Non-Sulfur Bacteria

open access: yes, 2021
Purple non-sulfur (PNS) bacteria have the ability to produce biohydrogen via photofermentation. This study focuseson hydrogen production using co-cultures of immobilized PNS bacteria, investigates the possible synergistic effectof their co-cultures, and ...

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

open access: yesThe 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.

An Innovative Device to Convert Olive Mill Wastewater into a Suitable Effluent for Feeding Purple Non-Sulfur Photosynthetic Bacteria

open access: yesResources, 2015
A device (prototype) with a working volume of 200 L was used to deplete olive mill wastewater (OMW) of polyphenols. The OMW transformed into feedstock by means of the device was then used for feeding a lab-scale photobioreactor, just for testing the ...

Hydrothermal origin of metabolic phosphorylation

open access: yesThe FEBS Journal, EarlyView.
Serpentinizing hydrothermal vents are candidate sites for biochemical origins. They generate extremely reducing conditions, depositing phosphite (HPO32−) and transition metals, including palladium, in the native (zero‐valent) state. Schlikker et al.

The purple photosynthetic sulfur bacteria of genus Chromatium, isolated from lakes Yavorivske (Lviv region) and Sakske (AR Crimea)

open access: yes, 2010
The photosynthetic purple sulfur bacteria were isolated from lakes Yavorivske (Lviv region) and Sakske (AR Crimea). The purple sulfur bacteria use reduced sulfur compounds as electron donors for anoxygenic photosynthesis. The elemental sulfur produced by

Periodontitis and Inflammatory Bowel Diseases: Mechanistic Evidence

open access: yesJournal of Periodontal Research, EarlyView.
This review aims to provide a conceptual framework for understanding the mechanistic interplay between periodontitis and IBD, with a particular emphasis on the microbial and immunological crosstalk linking the oral cavity and the gastrointestinal tract.
