Extraction and characterization of chitin and chitosan with antimicrobial and antioxidant activities from cosmopolitan Orthoptera species (Insecta)
(Korean Soc Biotechnology & Bioengineering, 2015)
This study examined two gregarious Orthoptera species (Calliptamus barbarus and Oedaleus decorus) as potential sources of chitin. The chitin content of the dry weight of C. barbarus was 20.5 +/- 0.7%, and it was 16.5 +/- ...
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 ...
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 ...
An environmental catalyst derived from biological waste materials for green synthesis of biaryls via Suzuki coupling reactions
(Elsevier Science Bv, 2016)
Synthesis of bio-macromolecular supported catalysts has gained much recent attention due to their greener nature. Among the biopolymers, chitosan is widely used as a support material due to its high affinity for metal ions. ...
Microwave assisted synthesis of biarlys by C-C coupling reactions with a new chitosan supported Pd(II) catalyst
(ELSEVIER SCIENCE BV, 2016)
In this study a new type chitosan-based support has been produced for Pd(II) catalyst and its catalytic performance in Suzuki C-C reactions has been studied under microwave irradiation without using any solvent. The chemical ...
Sustainable chitosan/starch composite material for stabilization of palladium nanoparticles: Synthesis, characterization and investigation of catalytic behaviour of Pd@chitosan/starch nanocomposite in Suzuki–Miyaura reaction
(Wiley, 2018)
We fabricated a green chitosan/starch composite as support material for stabilization of palladium nanoparticles for the first time. The chemical structure of the sustainable palladium nanocomposite was investigated using ...
Cu(II) and Pd(II) complexes of water soluble O-carboxymethyl chitosan Schiff bases: Synthesis, characterization
(Elsevier Science Bv., 2015)
This study reports the synthesis of two new water soluble O-carboxymethyl chitosan Schiff bases (OCMCS-5 and OCMCS-6a) and their Cu(II) and Pd(II) complexes. Characterizations of these complexes were carried out with FTIR, ...
Physicochemical characterization of chitin and chitosan obtained from resting eggs of ceriodaphnia quadrangula (branchiopoda: Cladocera: daphniidae)
(Crustacean SOC, 2014)
Chitin and chitosan were produced from the structures of the resting eggs of Ceriodaphnia quadrangula (Muller, 1785), of which tons are naturally produced in a dammed lake. On a dry weight basis, 16-17% chitin and 11% ...
Porous and nanofiber alpha-chitosan obtained from blue crab (Callinectes sapidus) tested for antimicrobial and antioxidant activities
(Elsevier, 2016)
Chitin was isolated using the classical chemical method from the shell of Callinectes sapidus. The chitin content in the dry weight of the crab shells was determined as 12.1%. Total chitosan yield was recorded as 76%. The ...
