Enzymatic Modification of Native Chitin and Conversion to Specialty Chemical Products

Marine Drugs, 2020
Chitin is one of the most abundant biomolecules on earth, occurring in crustacean shells and cell walls of fungi. While the polysaccharide is threatening to pollute coastal ecosystems in the form of accumulating shell-waste, it has the potential to be ...

Chitin-signaling-dependent responses to insect oral secretions in rice cells propose the involvement of chitooligosaccharides in plant defense against herbivores.

The Plant Journal
Plants recognize molecules related to a variety of biotic stresses through pattern recognition receptors to activate plant immunity. In the interactions between plants and chewing herbivores, such as lepidopteran larvae, oral secretions (OS) are ...

Recent Updates in Pharmacological Properties of Chitooligosaccharides

BioMed Research International, 2019
Chemical structures derived from marine foods are highly diverse and pharmacologically promising. In particular, chitooligosaccharides (COS) present a safe pharmacokinetic profile and a great source of new bioactive polymers. This review describes the antioxidant, anti-inflammatory, and antidiabetic properties of COS from recent publications. Thus, COS

Developing Active Bilayer Films Based on Poly(Lactic Acid) and Gelatin or Sodium Caseinate

Polymers for Advanced Technologies, Volume 37, Issue 4, April 2026.
ABSTRACT Bilayer films made from polymers with complementary properties, such as poly(lactic acid) (PLA) and proteins, loaded with active agents allow to produce materials with additional functionality compared to those used in conventional packaging. The objective of this research was the development of bilayer films based on PLA acting as the passive

The Medicago truncatula GRAS protein RAD1 supports arbuscular mycorrhiza symbiosis and Phytophthora palmivora susceptibility. [PDF]

, 2017
The roots of most land plants are colonized by symbiotic arbuscular mycorrhiza (AM) fungi. To facilitate this symbiosis, plant genomes encode a set of genes required for microbial perception and accommodation.

Entomopathogenic Potential of Cuticle‐Degrading Enzymes From Bacillus velezensis CE100 in the Biocontrol of Pine Aphid (Eulachnus thunbergii Wilson)

Entomological Research, Volume 56, Issue 4, April 2026.
ABSTRACT Pine aphids are notoriously destructive sap‐sucking pests of pine trees worldwide. We investigated the biocontrol efficacy of Bacillus velezensis CE100 through cuticle‐degrading enzymes, which degrade the cuticular structure of insect pests.

Silver nanoparticles incorporated with enzymatically derived chitooligosaccharides: preparation, characterization, and biological potential evaluation

Frontiers in Food Science and Technology
In this work, silver nanoparticles (AgNPs) were elaborated using a simple, low-cost, and reproducible method by thermal treatment at 90°C of chitooligosaccharides (COSs), produced by chitosan depolymerization using the digestives chitosanases from ...
