Recent Progress on Enzyme Immobilization: Materials, Strategies, and Applications

open access: yesFood Bioengineering, Volume 5, Issue 2, Page 220-243, June 2026.
Enzyme immobilization technology has undergone substantial evolution driven by advances in materials science. This review systematically examines the recent advances in enzyme immobilization since 2024, with a focused analysis of five major categories of enzyme carriers including covalent organic framework, metal‐organic frameworks, polymers, carbon ...

Nuclear Magnetic Resonance–Based Urinary Metabolic Profiling for Assessing Heat Stress–Related Incident Kidney Injury in Health‐Care Workers

open access: yesGeoHealth, Volume 10, Issue 6, June 2026.
Abstract During the COVID‐19 pandemic, heat stress (HS) was a serious occupational risk for health‐care workers (HCWs) wearing personal protective equipment, which limits heat dissipation and increases the risk of kidney injury. In this exploratory study, we assessed HS‐related changes in the urinary metabolites of 38 HCWs working at mobile COVID‐19 ...

p-Hydroxybenzoic Acid Synthesis in Mycobacterium tuberculosis [PDF]

open access: yesJournal of Biological Chemistry, 2005
Glycosylated p-hydroxybenzoic acid methyl esters and structurally related phenolphthiocerol glycolipids are important virulence factors of Mycobacterium tuberculosis. Although both types of molecules are thought to be derived from p-hydroxybenzoic acid, the origin of this putative biosynthetic precursor in mycobacteria remained to be established.

Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

open access: yesThe FEBS Journal, Volume 293, Issue 11, Page 3303-3319, June 2026.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Electrochemical Sensing and Assessment of Parabens in Hydro- Alcoholic Solutions and Water Using a Boron-Doped Diamond Electrode

open access: yesSensors, 2008
In this paper, the electrochemical behaviour of several parabens preservatives, i.e. esters of p-hydroxybenzoic acid, methyl-, ethyl- and propyl-4-hydroxybenzoates as methyl-, ethyl- and propyl-parabens (MB, EB, and PB), has been investigated at a ...

Tomato plants control leaf sodium levels to limit damage by Spodoptera littoralis larvae

open access: yesNew Phytologist, Volume 250, Issue 5, Page 3417-3427, June 2026.
Summary Sodium is an essential element for animal growth and survival. Here we test the hypothesis that plants exposed to insect feeding can translocate sodium from the feeding site to other plant organs as a defense strategy against phytophagous insects, which need sodium in their diet.

Polymorphism and thermodynamics of m-hydroxybenzoic acid

open access: yesEuropean Journal of Pharmaceutical Sciences, 2006
Solution and solid-state properties of m-hydroxybenzoic acid have been investigated. Two polymorphs were found where the monoclinic modification exhibits a higher stability than the orthorhombic form. The solubility of the monoclinic polymorph was determined between 10 and 50 degrees C in methanol, acetonitrile, acetic acid, acetone, water and ethyl ...

Gap Analysis of Metabolic Conversions of Off‐Flavors and Antinutrients in Plant‐Based Substrates

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT To drastically reduce the carbon footprint of the food production chain, a major shift towards alternatives to conventional meat and dairy products is required. The use of plant‐based proteins is a promising route, but it also comes with challenges: Plant‐based proteins often contain antinutritional factors and off‐flavors, which can ...

Oxygen Reaction of 4-hydroxybenzoate Monooxygenase

open access: yesZeitschrift für Naturforschung B, 1972
4-hydroxybenzoate hydroxylase from Ps. putida has been studied with regard to the oxygen interaction with the reduced flavin. By rapid scanning spectrophotometry and EPR-measurements of rapidly frozen mixtures no intermediate could be established either in the presence of 4-hydroxybenzoate or the dead-end inhibitor 6-hydroxynicotinic acid.
