Production and characterization of chitosan from shrimp waste
Chitosan has been produced from shrimp waste by chemical method involving demineralization, deproteinization and deacetylation. The quality of chitosan depends on the conditions of the chemical extraction process. The results showed that 3% HCI and 4% NaOH were suitable concentration for demineralization and deproteinization, respectively at ambient temperature (28±2 o C). Chitosan with a high ...
متن کاملExtraction of chitosan and its oligomers from shrimp shell waste, their characterization and antimicrobial effect
AIM The present study was performed to utilize the shrimp shell waste for chitin and chitosan production, characterization by Fourier transform infrared (FT-IR) technique and to evaluate the antimicrobial effects of chitosan oligomers produced by depolymerization of chitosan by nitrous acid. MATERIALS AND METHODS Chitosan was extracted from the shrimp shell waste by the chemical method and ch...
متن کاملExtraction and Characterization of Water Soluble Chitosan from Parapeneopsis Stylifera Shrimp Shell Waste and Its Antibacterial Activity
Preparation and characterization of water soluble chitosan was examined for their antibacterial activity from P. stylifera. The yield of crude chitosan and water soluble chitosan was 54.3 % and 87.8%. The FT-IR spectrum of chitin, chitosan and water soluble chitosan also determined and characterization was done and compared with standards. Compare to other bacterial strains S.auerus (18.3mm) ha...
متن کاملStudies 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 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...
