Studies on Chitin I. Enzymic Degradation of Chitin and Chitin Esters [PDF]

Australian Journal of Biological Sciences, 1954
A study has been made O'f the enzymic degradation of chitin and the sodium salt of chitin sulphuric acid by a chitinase prepared from the intestinal tract of the snail, Helix aspersa. It is shown that, in a citrate-phosphate buffer, the pH for optimum activity is 4.8 for both substrates.

Chitin mixed in potting soil alters lettuce growth, the survival of zoonotic bacteria on the leaves and associated rhizosphere microbiology [PDF]

, 2016
Chitin is a promising soil amendment for improving soil quality, plant growth, and plant resilience. The objectives of this study were twofold. First, to study the effect of chitin mixed in potting soil on lettuce growth and on the survival of two ...

Imobilisasi Asam Humat Pada Kitin Dan Aplikasinya Sebagai Adsorben Cr(III)

Indonesian Journal of Chemical Research, 2018
Immobilization of humic acid on chitin has been conducted and applied to the adsorption of Cr(III). The humic acid was isolated using NaOH 0.1 M, while chitin was isolated by deproteination of crab shells by using NaOH 3.5 % (w/v) and followed by ...

A biological approach to metalworking based on chitinous colloids and composites [PDF]

Adv. Funct. Mater. 2024, 2406800, 2022
Biological systems evolve with minimum metabolic costs and use common components, and they represent guideposts toward a paradigm of manufacturing that is centered on minimum energy, local resources, and ecological integration. Here, a new method of metalworking that uses chitosan from the arthropod cuticle to aggregate colloidal suspensions of ...

Determination of Carbohydrate Composition in Mealworm (Tenebrio molitor L.) Larvae and Characterization of Mealworm Chitin and Chitosan

Foods, 2021
Mealworm (Tenebrio molitor L.) is a classic edible insect with high nutritional value for substituting meats from vertebrates. While interest in mealworms has increased, the determination of carbohydrate constituents of mealworms has been overlooked ...

A structural and biochemical model of processive chitin synthesis [PDF]

, 2014
Chitin synthases (CHS) produce chitin, an essential component of the fungal cell wall. The molecular mechanism of processive chitin synthesis is not understood, limiting the discovery of new inhibitors of this enzyme class.

Chitin Synthesis and Degradation in Crustaceans: A Genomic View and Application

Marine Drugs, 2021
Chitin is among the most important components of the crustacean cuticular exoskeleton and intestinal peritrophic matrix. With the progress of genomics and sequencing technology, a large number of gene sequences related to chitin metabolism have been ...

Studies on Chitin VI. The Nature of ?- and ?-Chitins [PDF]

Australian Journal of Biological Sciences, 1965
Enzymic digestion, acidic hydrolysis, deuterium exchange, infrared absorption spectra, and differential thermal analysis of chitins show that not only do the structures of <x- and ~-chitins differ but that differences occur within the <x-chitins and within the ~-chitins. The crystalline structure within an <x-chitin varies and about 30% of the

Chitin nanofiber elucidates the elicitor activity of polymeric chitin in plants

Frontiers in Plant Science, 2015
Chitin, an N-acetyl-D-glucosamine polymer, is a component of fungal cell walls and a microbe/pathogen-associated molecular pattern that elicits plant defense responses.

Chitin Nanowhisker Aerogels [PDF]

ChemSusChem, 2013
AbstractChitin nanowhiskers are structured into mesoporous aerogels by using the same benign process used previously in our group to make cellulose nanowhisker aerogels. The nanowhiskers are sonicated in water to form a hydrogel before solvent‐exchange with ethanol and drying under supercritical CO2 (scCO2). Aerogels are prepared with various densities
