Freshwater Biology, Volume 71, Issue 4, April 2026.ABSTRACT In the wet Afrotropics, information on trophic diversity and resource use in freshwaters is extremely limited. Here we used stable isotope ratios (δ13C, δ15N) from food webs along the continuum of a coastal river in the Republic of the Congo to examine seasonal and spatial patterns of trophic diversity.

Bioscience, biotechnology, and biochemistry, 2013 The isoeugenol monooxygenase (iem) gene from Pseudomonas nitroreducens Jin1, responsible for the conversion of isoeugenol to vanillin, was cloned and overexpressed in Escherichia coli. The purified Iem had a predicted molecular mass of 54 kDa. The V(max), K(M), and k(cat) values for it, using isoeugenol as substrate, were 4.2 µmol vanillin min(-1) mg ...

Depolymerisation of γ‐Valerolactone Organosolv Lignins with Unsupported Molybdenum‐Based Catalysts
ChemSusChem, Volume 19, Issue 3, February 2026.Lignins from γ‐valerolactone organosolv fractionation were depolymerised in ethanol using unsupported molybdenum catalysts. Over 90% yields of low‐molecular‐weight lignin oil were obtained with minimal char formation, yields of the aromatic monomers being 7–16 wt%.

Significant exposures to isoeugenol derivatives in perfumes
, 2008 Background: Isoeugenol, an important fragrance allergen in consumers, has been restricted to 200 p.p.m. since 1998 according to guidelines issued by the fragrance industry. However, no decline in contact allergy to isoeugnol has been detected.
