Valorization of Garcinia humilis Residues in Active Collagen/Starch Films for Biodegradable Packaging Applications

Packaging Technology and Science, EarlyView.
Residues from Garcinia humilis were used to obtain a phenolic‐rich extract (GHRE) and incorporated into collagen–starch films. The addition of GHRE improved antioxidant activity, thermal stability and elasticity, while reducing water vapour permeability.

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE

Acta Crystallographica Section D, EarlyView.
This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...
