Alizarin Dye: Toxicity, Genotoxicity, and Histopathological Alterations in Model Organisms

Environmental and Molecular Mutagenesis, Volume 67, Issue 3, March 2026.
ABSTRACT Alizarin is an anthraquinone red dye from natural or synthetic sources, widely used in textiles. Effluents of this activity can contain residual dyes, which may contaminate the aquatic environment. Studies report alizarin's aquatic toxicity, mutagenic, and carcinogenic effects. This study aimed to complement the aquatic toxicity evaluation and

Novel Manufacturing of Cellulose‐Based Membranes for Energy Storage Devices: Toward a PFAS Free Future

Advanced Sustainable Systems, Volume 9, Issue 12, December 2025.
This work presents a novel, scalable method for manufacturing PFAS‐free cellulose‐based membranes for energy storage devices. By coating kraft paper with cellulose nanofibrils and optimizing barrier and ionic conductivity properties, membranes are achieved that prevent redox molecule crossover while maintaining performance.

Effect of Shear Stress on Anthraquinones Production by Rubia tinctorum Suspension Cultures [PDF]

Biotechnology Progress, 2008
Suspension cultures of Rubia tinctorum, an anthraquinones (AQs) producer, were grown both in Erlenmeyer flasks at 100 rpm and in a 1.5 L mechanically stirred tank bioreactor operating at 450 rpm. The effect of hydrodynamic stress on cell viability, biomass, and AQs production was evaluated.

Effect of organic biocolourants on lightfastness and mechanical properties of polylactic acid

Coloration Technology, Volume 141, Issue 6, Page 921-931, December 2025.
Abstract Most modern colourants are acquired from petroleum‐based sources or mining, which often causes environmental degradation. Consequently, alternative colouring solutions are sought, such as using biocolourants, which are organic colourants from bio‐based sources.
