Mild extraction preserves labile structural features of Gram-positive bacterial cell wall glycopolymers

This paper introduces a mild extraction method for Gram-positive bacterial cell wall glycopolymers that preserves structural integrity and yields 17 distinct glycopolymers from 11 species.

Biodegradation of components from an oxidized polyethylene by a Rhodococcus strain isolated from the gut of Atlantic Salmon

This study identifies a Rhodococcus strain from Atlantic salmon gut capable of degrading oxidized polyethylene derivatives, revealing key enzymes and mechanisms involved in the process.

Production and evaluation of fluorophore-doped polymer substrates to screen for plastic-degrading enzymes

The paper develops a fluorescent probe-based method to screen plastic-degrading enzymes using rhodamine-doped polymer substrates and validates it with PET and polyethylene materials.

High molecular-weight polysaccharide contamination from yeast extract in semi-defined bacteriological media: Effects on exopolysaccharide production and purity

This study identifies high molecular weight polysaccharide contaminants in yeast extract that affect exopolysaccharide (EPS) purity and structural analysis, showing their removal via ultrafiltration.

Functional characterization of multi-domain LPMOs from marine Vibrio species reveals modulation of enzyme activity by domain-domain interactions

The paper functionally characterizes multi-domain LPMOs from marine Vibrio species, revealing that domain-domain interactions modulate enzyme activity by regulating copper site accessibility.

Whole genome assembly and annotation of the Bumblebee Wax Moth, Aphomia sociella

This paper presents a high-quality genome assembly and annotation for the bumble bee wax moth, Aphomia sociella, using long-read sequencing, and places it phylogenetically within the Lepidoptera order.

Discovery and characterization of bacterial unspecific peroxygenase-like heme-thiolate enzymes

The paper discovers and characterizes a new family of bacterial heme-thiolate peroxygenases, showing structural and functional similarities to eukaryotic UPOs.

Microbial degradation of a widely used model polyethylene is restricted to medium- and long-chain alkanes and their oxidized derivatives

The paper identifies microbial communities capable of degrading medium- and long-chain alkanes and their oxidized derivatives in polyethylene, revealing the presence of these compounds in the model PE material.

Revisiting the activity of two poly(vinyl chloride)- and polyethylene-degrading enzymes

This study attempts to replicate two recent claims of enzymatic degradation of polyethylene and poly(vinyl chloride) but finds no activity under various conditions, suggesting previous results may have been misinterpreted.

Gene family expansion and functional diversification of chitinase and chitin synthase genes in Atlantic salmon (Salmo salar)

The paper investigates the expansion and functional diversification of chitinase and chitin synthase genes in Atlantic salmon using comparative genomics, transcriptomics, and chromatin accessibility data.
