Seafood waste: a source for preparation of commercially employable chitin/chitosan materials

Bioresources and Bioprocessing, 2019
Modern seafood processing practices result in amassment of a large volume of waste products, i.e., skin, head, tails, shells, scales, backbones, etc. These waste products may often encompass several high-value products which are still untapped due to the

Structural Polymorphism of Chitin and Chitosan in Fungal Cell Walls From Solid-State NMR and Principal Component Analysis

Frontiers in Molecular Biosciences, 2021
Chitin is a major carbohydrate component of the fungal cell wall and a promising target for novel antifungal agents. However, it is technically challenging to characterize the structure of this polymer in native cell walls. Here, we recorded and compared

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

Advanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Structural and Material Properties of Chitin Nanofibers Produced Without Deacetylation Treatment

Nano Select
Deacetylation pretreatment is commonly applied to chitin nanofibers to introduce positive charges on their surface, increasing their fibrillation efficiency in water. However, without this treatment, chitin cannot be easily disintegrated into fibers with

Efficacy of chitinases from mangrove wetland derived Penicillium oxalicum on powdered chitin

Frontiers in Microbiology
Chitin, an abundant polysaccharide in shrimp and crab shells, serves as a primary resource for producing glucosamine and chitosan oligosaccharides. Chemical hydrolysis is widely utilized in these processes, due to the limited efficacy of many chitinases ...

The Chitin Connection [PDF]

mBio, 2012
ABSTRACTChitin, a polymer ofN-acetylglucosamine, is an essential component of the fungal cell wall. Chitosan, a deacetylated form of chitin, is also important in maintaining cell wall integrity and is essential forCryptococcus neoformansvirulence. In their article, Gilbert et al. [N. M. Gilbert, L. G. Baker, C. A. Specht, and J. K.

Biobased Bionic Spider Silk via Electrostatic Complexation for Simultaneously Harvesting Atmospheric Water and Triboelectric Energy

Advanced Functional Materials, EarlyView.
Bio‐based bionic spider silk and spider web are first prepared using polyelectrolyte complexation technique for the simultaneous harvesting of water and triboelectric energy. The advantage of this process lies on entirely bio‐based materials, fully green water‐processable procedures, extremely high production rate (99.36%), excellent fog harvesting ...

Genome-Wide Mining of Chitinase Diversity in the Marine Diatom Thalassiosira weissflogii and Functional Characterization of a Novel GH19 Enzyme

Marine Drugs
Chitin represents a globally abundant marine polymer with significant ecological and biotechnological value. β-chitin is an important carbon fixation product of diatoms and has a greater range of applications than α- and γ-chitin. However, there has been

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

Advanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

A secreted LysM effector protects fungal hyphae through chitin-dependent homodimer polymerization.

PLoS Pathogens, 2020
Plants trigger immune responses upon recognition of fungal cell wall chitin, followed by the release of various antimicrobials, including chitinase enzymes that hydrolyze chitin.
