From static difference to time-resolved spectroscopy of coupled electron and proton transfer in the quinol: fumarate reductase of Wolinella succinogenes [PDF]

open access: yes, 2011
The enzyme quinol:fumarate reductase (QFR) from the anaerobic epsilon-proteobacterium Wolinella succinogenes is a membrane protein complex that couples the catalysis of the oxidation of menaquinol to menaquinone to that of the reduction of fumarate to ...

Stage‐Dependent Metabolic Reprogramming Drives a Self‐Organizing Microbial Network During Shanxi Aged Vinegar

open access: yesFood Bioengineering, EarlyView.
Metabolic shifts from growth to stress adaptation in Shanxi aged vinegar fermentation link flavor maturation and microbial cooperation, and Lactobacillus and Acetobacter form a self‐organizing metabolic network through division of labor. ABSTRACT Acetic acid fermentation (AAF) is a vital stage in the production of Shanxi aged vinegar (SAV), during ...

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

open access: yesFood Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Metabolite Profiles and Antioxidant Activity of Dendrobium catenatum Under Simulated Wild Cultivation

open access: yesFood Safety and Health, EarlyView.
Dendrobium catenatum grown under simulated wild cultivation showed significantly higher flavonoids and stilbenes, leading to enhanced antioxidant activity in both leaves and stems compared to facility‐grown plants. Integrated metabolomics, antioxidant assays, and network pharmacology identified Denbinobin as a key multi‐target antioxidant compound ...
