Extensive Microbial Processing of Polysaccharides in the South Pacific Gyre via Selfish Uptake and Extracellular Hydrolysis

Frontiers in Microbiology, 2020
Primary productivity occurs throughout the deep euphotic zone of the oligotrophic South Pacific Gyre (SPG), fueled largely by the regeneration of nutrients and thus recycling of organic matter.

Thiolated Hyaluronic Acid: A Gateway for Targeted Killing of Staphylococcus aureus on the Race for Surface Colonization

Advanced Healthcare Materials, EarlyView.
Thiolated hyaluronic acid (HAMS) synthesized and characterized by NMR, solubility, thiol content, and pKa, is degraded by Staphylococcal hyaluronate lyase but not by mammalian hyaluronidase. Coating polyphosphate–M23 phage endolysin nanoparticles (M23‐PP) with HAMS confers Staphylococcus aureus responsiveness.

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

Advanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

Evaluation of polysaccharides content in fruit bodies and their antimicrobial activity of four Ganoderma lucidum (W Curt.: Fr.) P. Karst. strains cultivated on different wood type substrates

Acta Societatis Botanicorum Poloniae, 2012
Quantitative determination of polysaccharides in Ganoderma lucidum fruit bodies from different sawdust cultivation substrates and their antibacterial activity was done. Thirty six samples were analyzed. Four strains of Ganoderma lucidum (GL01, GL02, GL03

Polysaccharides Coatings on Medical-Grade PVC: A Probe into Surface Characteristics and the Extent of Bacterial Adhesion

Molecules, 2010
Medical-grade polyvinyl chloride was coated by polysaccharides through a novel physicochemical approach. An initial surface activation was performed foremost via diffuse coplanar surface barrier discharge plasma in air at ambient temperature and pressure.

Nanoarchitectonics of Metal–Organic Framework and Nanocellulose Composites for Multifunctional Environmental Remediation

Advanced Materials, EarlyView.
Nanoscale metal–organic frameworks (MOFs) and nanocellulose composites have significant potential for the multi‐functional remediation of the environment. This review focused on the synthesis strategies (in situ growth, ex situ growth, and other approaches), typical forms (aerogel, hydrogel, beads, and membrane), and applications in the removal of ...
