Callinectes sapidus'dan kitin, kitosan izolasyonu ve fizikokimyasal karakterizasyonu
(Aksaray Üniversitesi Fen Bilimleri Enstitüsü, 2015)
Crustaceae familyasının üyesi olan Callinectes sapidus türü yengeçler dünya üzerinde geniş bir dağılıma sahiptir. Canlı kabuğunun iç kısmı besin olarak tüketildiğinden ekonomik değere sahiptir. Canlı dış kabuğunu ...
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, ...
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 ...
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 +/- ...
Microbial biofilm activity and physicochemical characterization of biodegradable and edible cups obtained from abdominal exoskeleton of an insect
(Elsevier Ltd., 2016)
A contemporary focus in food industry is the use of edible bio-based products with properties such as antimicrobial and biodegradable to replace the synthetic harmful petroleum-based polymers. Among the natural polysaccharides, ...
High similarity in physicochemical properties of chitin and chitosan from nymphs and adults of a grasshopper
(Elsevier Science Bv, 2016)
This is the first study to explain the differences in the physicochemical properties of chitin and chitosan obtained from the nymphs and adults of Dociostaurus maroccanus using the same method. Fourier transform infrared ...
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 ...
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% ...
Chitosan nanofiber production from Drosophila by electrospinning
(Elsevier Science Bv, 2016)
Drosophila melanogaster is one of the important test organisms in genetics thanks to its fast growth rate in a culture. This study demonstrates that the fly D. melanogaster can also be exploited as a source for nanofiber ...
