Upgrading of the bio-based platform chemical 5-hydroxymethylfurfural (HMF) into high-value derivatives is an important research topic, particularly in green and sustainable chemistry. Herein, we applied a new, highly HMF-tolerant strain, Enterobacter ludwigii YYP3, as a whole-cell biocatalyst for efficient reduction of HMF to 2,5-bis(hydroxymethyl)...

Sour beers produced by barrel-aging of conventionally fermented beers are becoming increasingly popular. However, as the intricate interactions between the wood, the microbes and the beer are still unclear, wood maturation often leads to inconsistent end products with undesired sensory properties. Previous research on industrial barrel-aging of bee...
The intestinal absorption of dietary catechins is quite low, resulting in most of them being metabolized by gut microbiota in the colon. It has been hypothesized that microbiota-derived metabolites may be partly responsible for the association between catechin consumption and beneficial cardiometabolic effects. Given the profound differences in gut...
With the advent of small-scale robotics, several exciting new applications like Targeted Drug Delivery, single cell manipulation and so forth, are being discussed. However, some challenges remain to be overcome before any such technology becomes medically usable; among which propulsion and biocompatibility are the main challenges. Propulsion at mic...
Limited information is available on arsenic (As) release from As-loaded algae precipitated from As contaminated water and its subsequently appropriate disposal. In this study, selected M. aeruginosa as algal model, changes of As concentrations and its speciation were thus investigated in the in-situ treated algae water by optimal coagulation. Meanw...

The occurrence at different trophic levels of 17 poly- and perfluoroalkyl substances (PFASs), including perfluoroalkyl acids (PFAAs) and some of their precursors (e.g., perfluoroalkane sulfonamides, 6:2 fluorotelomer sulfonate (6:2 FTSA)), was investigated in riverine freshwater food webs in Southeastern France. Two fish species (Barbus barbus and ...
The pharmacokinetics of diclofenac were investigated following single oral doses of 10 mg/kg to chimeric liver humanized and murinized FRG and C57BL/6 mice. In addition, the metabolism and excretion were investigated in chimeric liver humanized and murinized FRG mice. Diclofenac reached maximum blood concentrations of 2.43 ± 0.9 µg/mL (n = 3) at 0....
Ochratoxin A (OTA, 0.25 mg/kg body weight) was absorbed rapidly (T-max = 0.31-1.88 h) in all avian species (broiler chickens, laying hens, turkeys, and Muscovy ducks) but more slowly in broiler chickens (T-max = 1.43-4.63 h). The absolute oral bioavailability was complete in these bird species (88.0-109.6%). Ducks have a significantly higher volume...
Les PolyBromo Diphényl Éther, retardateurs de flammes, sont des substances réglementées classées substances prioritaires par la Directive-cadre sur l'eau (DCE) (2000/60/EC). Les mesures actuelles prévues par la DCE s'appuient sur des normes de qualité environnementale qui renseignent peu sur la biodisponibilité des substances. Des études de bioaccu...
