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 ...
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, ...
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. ...
Conversion of waste parasitic insect (Hylobius abietis L.) into antioxidative, antimicrobial and biodegradable films
(Tech Science Press, 2019)
Hylobius abietis is a plant parasitic insect belonging to the order Coleoptera and which causes severe damages to coniferous forests in Northern and Eastern Europe. This current study is aimed to provide a new viewpoint ...
Production and characterization of chitosan-fungal extract films
(Elsevier Ltd, 2020)
A fungal extract obtained from an edible species (Tricholoma terreum) was used to produce chitosan-based films. Fungal extracts were analyzed using HPLC and chitosan-based films were characterized with FT-IR, SEM, DSC and ...
Use of sea urchin spines with chitosan gel for biodegradable film production
(Elsevier B.V., 2020)
In recent years, the film production from natural polymers has considerably increased in food industry as an alternative to the petroleum based synthetic films. Chitosan is one of the most preferred biopolymers for bio-based ...
Current advancements in chitosan-based film production for food technology; A review
(Elsevier Science Bv., 2019)
Chitosan is obtained from chitin, which could be considered to be the most abundant polymer after cellulose. Owing to these properties, chitosan alone or chitosan-based composite film production is attaining huge attention ...
