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 ...
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, ...
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. ...
Preparation and characterisation of biodegradable pollen-chitosan microcapsules and its application in heavy metal removal
(Elsevier, 2015)
Biosorbents have been widely used in heavy metal removal. New resources should be exploited to develop more efficient biosorbents. This study reports the preparation of three novel chitosan microcapsules from pollens of ...
Antitumor activity of chitosan from mayfly with comparison to commercially available low, medium and high molecular weight chitosans
(Springer, 2018)
Insects' cuticles have a potential to be evaluated as a chitin source. Especially adults of aquatic insects like mayflies (order Ephemeroptera) swarm in enormous numbers in artificially lit areas while mating in spring and ...
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 ...
