Physicochemical and Antibacterial Properties of Chitosan Extracted from Waste Shrimp Shells
This research aims to study the production of chitosan from shrimp shell (Litopenaeus vannamei) of waste origin using two chemical methodologies involving demineralization, deproteinization, and the degree of deacetylation. The evaluation of the quality of chitosan from waste shrimp shells includes parameters for the yield, physical chemistry characteristics by infrared spectroscopy (FT-IR), th...

Studies on heavy metal removal efficiency and antibacterial activity of chitosan prepared from shrimp shell waste
Chitosan, a natural biopolymer composed of a linear polysaccharide of α (1-4)-linked 2-amino 2-deoxy β-D glucopyranose was synthesized by deacetylation of chitin, which is one of the major structural elements, that forms the exoskeleton of crustacean shrimps. The present study was undertaken to prepare chitosan from shrimp shell waste. The physiochemical properties like degree of deacetylation ...
متن کاملPhysicochemical properties and bioactivity of fungal chitin and chitosan.
Chitinous material was extracted from mycelia of Aspergillus niger and Mucor rouxii grown in yeast peptone dextrose broth for 15 and 21 days, respectively. The extracted material was characterized for purity, degree of acetylation, and crystallinity and tested for antibacterial and eliciting properties. The maximum glucosamine level determined in the mycelium of A. niger was 11.10% dw and in th...
متن کاملChitin and Chitosan: Structure, Properties and Applications
Chitin and chitosan are the most abundant natural amino polysaccharide that are non-toxic, biodegradable and biocompatible. They have become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields. They are biopolymers having immense structural possibilities for chemical and mechanical modifications to generate novel pro...
