Exploring the Controllability of Microbial Metabolism on the Flavor of Chinese Baijiu

eFood, Volume 7, Issue 1, February 2026.
Regulation of flavor compounds by core functional microorganisms. ABSTRACT The flavor and quality of Baijiu are closely related to the environment and microbial metabolism. The microbial community structure is highly dynamic in time and space, making it trouble to control the flavor and quality of Baijiu. Therefore, this paper reviewed the role of core

Microbial metabolites in tumor epigenetic regulation

iMeta, Volume 5, Issue 1, February 2026.
The gut microbiome modulates tumor epigenetic regulation through bioactive metabolites derived from dietary substrates. Microbiota‐produced SCFAs, secondary BAs, one‐carbon metabolites, and tryptophan‐derived ligands regulate histone acetylation, DNA methylation, and chromatin remodeling via HDAC, DNMT, AhR, and metabolic cofactor‐dependent pathways ...

Sorbent coatings for solid-phase microextraction targeted towards the analysis of death-related polar analytes coupled to comprehensive two-dimensional gas chromatography: comparison of zwitterionic polymeric ionic liquids versus commercial coatings [PDF]

, 2020
Decomposition of bodies generates several types of polar volatile organic compounds (VOCs), whose types, patterns and ratios change during the various stages of decomposition and, therefore, their determination has huge potential to provide useful ...

Glucuronoyl Esterase of Pathogenic Phanerochaete carnosa Induces Immune Responses in Aspen Independently of Its Enzymatic Activity

Plant Biotechnology Journal, Volume 24, Issue 2, Page 602-619, February 2026.
ABSTRACT Microbial enzymes expressed in plants add new functionalities but occasionally trigger undesirable immune responses. Phanerochaete carnosa glucuronoyl esterase (PcGCE) hydrolyses the bond between lignin and 4‐O‐methyl‐α‐D‐glucuronic acid substituent of glucuronoxylan.

Photoelectron Spectroscopy of the Phosphorus Monosulfide (PS) and Phosphorus Monoxide (PO) Radicals

Small Structures, Volume 7, Issue 1, January 2026.
Sketch of the experiment to measure the photo electron spectrum of the PS radical produced in situ with a mixture of PH3, H2S and F atoms. PO and PS radicals are the smallest units of phosphorus oxides and phosphorus sulfides, respectively, two rich families of refractory compounds widely employed in industrial and technological applications. These two

Metabolomics for Age Discrimination of Ginseng Using a Multiplex Approach to HR-MAS NMR Spectroscopy, UPLC–QTOF/MS, and GC × GC–TOF/MS

Molecules, 2019
(1) Background: The ability to determine the age of ginseng is very important because the price of ginseng depends on the cultivation period. Since morphological observation is subjective, a new scientific and systematic method for determining the age of

JAXA curation for Bennu samples returned by the NASA's OSIRIS‐REx mission

Meteoritics &Planetary Science, Volume 61, Issue 1, Page 182-207, January 2026.
Abstract NASA's OSIRIS‐REx mission successfully collected and returned ~121.6 g of bulk samples from the B‐type, near‐Earth asteroid (101955) Bennu to Earth in September 2023. Upon returning to Earth, the samples were transported to the NASA Johnson Space Center where most of the samples have been stored and processed.

The Characterization of the Key Aroma Compounds in Non-Smoked Bacon by Instrumental and Sensory Methods

Foods
The aroma profiles in non-smoked bacon were investigated via GC–O–MS, GC × GC–TOFMS, and GC–IMS. GC-O-MS is advantageous for detecting aldehydes. GC × GC-TOFMS is more sensitive to hydrocarbons and alcohols, while GC-IMS detects a balanced range of ...
