Extraction 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 کاملProduction 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 کاملThe antimicrobial of chitin and chitosan extracted from shrimp shell (Palameon elegans)
Palaemon elegans are distributed over a wide coastline of ocean and sea waters. distilled form (chitosan) is a natural polymer with antimicrobial properties that is naturally present in the exoskeleton of crustaceans, including shrimp. Chitin and chitosan are widely used in the pharmaceutical, cosmetic, agricultural, biomedical, food preparation and storage industries. 977 pieces of P. elegans ...
متن کاملAntimicrobial and Antifungal Effects of Acid and Water-Soluble Chitosan Extracted from Indian Shrimp (Fenneropenaeus indicus) Shell
Background & Objective : Currently, efforts are underway to seek new and effective antimicrobial agents, and marine resources are potent candidates for this aim. The following study was conducted to investigate the efficacy of water-soluble and acid-soluble chitosan against some pathogenic organisms. Materials & Method s: Inhibition zone of different concentrations (5, 7.5, and 10 mg/ml) of a...
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...
