Chitin and Chitosan: Sustainable, Medically Relevant Biomaterials [PDF]
, 2017 The polysaccharides chitin and chitosan are made up of monomer units of the amino sugars D-glucosamine and N-acetyl-D-glucosamine. The ratio of these two monomers dictates whether the polysaccharide is considered chitin or chitosan.

Limnology and Oceanography, EarlyView.Abstract Nutrient dynamics in headwater streams are governed by benthic and hyporheic biofilms, with carbon (C) : nitrogen (N) : phosphorus (P) ratios driving the heterotrophic microbial biofilm development through nutrient limitation. Furthermore, heterotrophic responses to changes in C : N : P ratios are probably modulated by autotrophic responses to

PLoS ONE, 2014 Chitosan is a linear heteropolymer consisting of β 1,4-linked N-acetyl-D-glucosamine (GlcNAc) and D-glucosamine (GlcN). We have compared the antifungal activity of chitosan with DPn (average degree of polymerization) 206 and FA (fraction of acetylation ...

Quantifying biosynthetic network robustness across the human oral microbiome [PDF]
, 2018 Metabolic interactions, such as cross-feeding, play a prominent role in microbial communitystructure. For example, they may underlie the ubiquity of uncultivated microorganisms.

Macromolecular Chemistry and Physics, EarlyView.A new unnatural heteroaminopolysaccahride, that is, α(1→$1{\to} $4)‐linked glucosamino‐2‐deoxyglucan, is successfully synthesized by thermostable glucan phosphorylase (from Aquifex aeolicus VF5)‐catalyzed enzymatic copolymerization of α‐d‐glucosamine 1‐phosphate/‐glucal as comonomers from maltotriose as a primer.

In Situ Gels for Nasal Delivery: Formulation, Characterization and Applications
Macromolecular Materials and Engineering, EarlyView.Drug delivery through the nasal route offers many advantages, but is hampered by a number of challenges, such as the short drug retention time caused by mucociliary clearance. In situ forming gels, which undergo a sol‐to‐gel transition with specific triggers at the site of action, present real opportunities in this field.

Macromolecular Rapid Communications, EarlyView.A multifunctional aqueous composite binder is developed for Li–S batteries by using catechol‐conjugated chitosan covalent bonded with multi‐wall carbon nanotubes. The strong polysulfide adsorption and improved mechanical properties lead to crack‐free electrodes and improved adhesion.
