Comparison of chitin structures derived from three common wasp species (vespa crabro linnaeus, 1758, vespa orientalis linnaeus, 1771 and vespula germanica (FABRICIUS, 1793))
(John Wiley and Sons Limited, 2015)
There has been no study on the chitin structure of wasp species. Here, we selected the three most common wasp species belonging to the family Vespidae for chitin extraction and characterization. Chitin was isolated from ...
The presence of α-chitin in Tardigrada with comments on chitin in the Ecdysozoa
(Elsevier GmbH, 2016)
We used Fourier Transform Infrared Spectroscopy (FT-IR) to characterize for the first time chitin in the cuticle of a eutardigrade (Macrobiotus cf. hufelandi). Analysis of the isolated cuticles of single individuals and ...
Green heterogeneous Pd(II) catalyst produced from chitosan-cellulose micro beads for green synthesis of biaryls
(Elsevier Ltd., 2016)
In green catalyst systems, both the catalyst and the technique should be environmentally safe. In this study we designed a green palladium(II) catalyst for microwave-assisted Suzuki C C coupling reactions. The catalyst ...
Bat guano as new and attractive chitin and chitosan source
(BioMed Central Ltd., 2014)
Introduction: Chitin is a biopolymer that forms the exoskeleton of arthropods, and is found in the cell walls of fungi. It has a wide range of uses in fields such as cosmetics, pharmacy, medicine, bioengineering, agriculture, ...
Physicochemical comparison of chitin and chitosan obtained from larvae and adult Colorado potato beetle (Leptinotarsa decemlineata)
(Elsevier Science Bv, 2014)
Chitins and chitosans obtained from larva and adult Coloradopotato beetles (Leptinotarsa decemlineata) were physico-chemically characterized and differences between adults and larvae were identified. The dry weight chitin ...
Extraction and characterization of alpha-chitin and chitosan from six different aquatic invertebrates
(Springer, 2014)
Chitin and chitosan were extracted from six different aquatic invertebrate species. Species dry weights varied between 5 % and 20 % chitin, and the chitosan productivity of these chitins varied between 66 % and 74 %. Chitin ...
Differentiations of chitin content and surface morphologies of chitins extracted from male and female grasshopper species
(Public Library Science, 2015)
In this study, we used Fourier transform infrared spectroscopy (FT-IR), elemental analysis (EA), thermogravimetric analysis (TGA), X-ray diffractometry (XRD), and scanning electron microscopy (SEM) to investigate chitin ...
Chitin extraction and characterization from Daphnia magna resting eggs
(Elsevier Science Bv, 2013)
New application areas for chitin and its derivatives have been extensively investigated and there is a solid, growing demand for new chitin sources. In this present study, chitin content of Daphnia magna resting egg (18-21%) ...
A physicochemical characterization of fully acetylated chitin structure isolated from two spider species: With new surface morphology
(Elsevier, 2014)
Spiders are a huge group which includes more than 44,000 species. But there has been no study of the chitin structure of spiders. In this study we physicochemically characterized chitin structure of two common spider species ...
New chitin, chitosan, and O-carboxymethyl chitosan sources from resting eggs of Daphnia longispina (Crustacea); with physicochemical characterization, and antimicrobial and antioxidant activities
(Korean Soc Biotechnology & Bioengineering, 2014)
The paper describes the isolation and characterization of chitin and chitosan from Daphnia longispina resting eggs harvested from a reservoir. Resting eggs are fertilized eggs that are encased in chitinous shells called ...
