The Dairy Ruminant Gut Microbiome: Profile, Responsiveness to Seasonality and Impact on Milk Quality

open access: yesEnvironmental Microbiology, Volume 28, Issue 5, May 2026.
The dairy ruminant gut microbiome that is shaped by host and diet is affected by seasonality and rearing. These factors can impact dairy productivity and milk quality potentially through the gut microbiota. ABSTRACT The gut microbiome (GM) and particularly the rumen microbiome (RM) affect the ruminant health and they are associated with milk quality ...

Toxicity of Ethyl Formate to Tribolium castaneum (Herbst) Exhibiting Different Levels of Phosphine Resistance and Its Influence on Metabolite Profiles

open access: yesAgriculture
Ethyl formate (EF), a naturally occurring fumigant, has attracted widespread attention owing to its low toxicity in mammals. Here, Direct Immersion Solid-Phase Microextraction (DI-SPME) was employed for sample preparation in mass spectrometry-based ...

Complex organic molecules in the interstellar medium: IRAM 30 m line survey of Sagittarius B2(N) and (M)

open access: yes, 2013
The discovery of amino acids in meteorites and the detection of glycine in samples returned from a comet to Earth suggest that the interstellar chemistry is capable of producing such complex organic molecules.

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 ...

Proton Solvation in Water and Selected Organic Solvents: A Critical Assessment of Experimental and Theoretical Approaches to Extend the Solvent‐Independent Unified Acidity Scale

open access: yesChemPhysChem, Volume 27, Issue 8, 28 April 2026.
The (solvated) proton is the most elusive chemical entity, both by experimental and by theoretical means. Visit this special exhibition, explore the proton´s structure and chemical potential in water and various organic solvents. Let yourself be fascinated by its many facets and be there when it is unified.

A Three‐Step Route to Functionalized Pyrrole‐2,5‐Dicarboxylic Acids from Galactaric Acid

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
Galactaric acid (GalA) has been used as substrate for a library of N‐substituted pyrrole‐2,5‐dicarboxylic acids (PDCAs). Existing routes to N‐substituted PDCAs require many steps or lack product isolation. We present a simple, scalable three‐step synthesis from GalA via a 2‐pyrone salt, giving isolated PDCA derivatives in high yield without ...

The Relationship Between Catalyst and Solvent in Hydrogenation via Condensed Phase Heterogeneous Catalysis

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
Heterogeneous catalysis has historically been developed in the gas phase, however, we have found it pertinent to highlight solvent effects that must be accounted for in liquid environments. Condensed phase catalysis, like that in biomass, petroleum and the conversion of CO2, stands to benefit from the typically overlooked discussion regarding the ...
