Exploring Different Methods for Eco‐Friendly Wool Dyeing with Natural Carmine Dye and Waste Wool Hydrolysates

open access: yesGlobal Challenges, EarlyView.
Waste wool hydrolysates (WWHs), by‐product of the alkaline hydrolysis of waste wool are employed as coadjuvant in wool fabrics dyeing with Carmine natural dye. The results demonstrate the possibility of WWHs valorization as eco‐friendly alternative to metal‐based mordants in wool dyeing.

Magnetite Nanoparticles Enhancing H2‐Driven Biomethanation in a Mixed Microbial Community

open access: yesGlobal Challenges, EarlyView.
Supplementation of magnetite nanoparticles to a mixed microbial culture accelerates H2/CO2 biomethanation by up to 13‐fold. The observed enhancement is accompanied by a marked enrichment of Paracoccus sp., suggesting the establishment of a mutualistic interaction with hydrogenotrophic methanogens via interspecies electron transfer.
