Von-Hippel Lindau protein amyloid formation. The role of GST-tag
Biochem Biophys Res Commun. 2024 Apr 25;715:150008. doi: 10.1016/j.bbrc.2024.150008. Online ahead of print.ABSTRACTIn the last decade, much attention was given to the study of physiological amyloid fibrils. These structures include A-bodies, which are the nucleolar fibrillar formations that appear in the response to acidosis and heat shock, and disassemble after the end of stress. One of the proteins involved in the biogenesis of A-bodies, regardless of the type of stress, is Von-Hippel Lindau protein (VHL). Known also as a tumor suppressor, VHL is capable to form amyloid fibrils both in vitro and in vivo in response to th...

Silane and fluorine free facile hydrophobicization of water hyacinth biomass for oil-water separations
In this study, we extracted cellulose from water hyacinth (WH) biomass, known for its negative environmental impact, and converted it into hydrophobic cellulose. This addresses the issue of managing WH waste and creating an environmentally friendly hydrophobic material. Initially, aldehyde groups were introduced through oxidation with periodate, followed by direct octadecyl amine (ODA) grafting onto dialdehyde cellulose (DAC) via a Schiff base condensation. The resulting ODA modified cellulose (ODA-C) was dispersed in ethanol and used to coat various materials, including cotton fabric, cellulose filter paper, and packaging...

How to develop a bio-based phosphorus mining strategy for eutrophic marine sediments: Unlocking native microbial processes for anaerobic phosphorus release
This study examined the anaerobic release of phosphorus (P) from two different Baltic Sea sediments (B and F), focusing on the impact of initial concentration of externally introduced waste-derived volatile fatty acids (VFA) as the carbon source, temperature, pH, and mixing conditions. The first batch bioreactor set was operated to demonstrate the effect of VFA on anaerobic P release at different concentrations (1000-10000 mg/L as COD) at 20 °C. A notable P release of up to 15.85 mg/L PO4-P was observed for Sediment B at an initial carbon concentration of 10000 mg COD/L. However, VFA consumption in the bioreactors was min...
