Production of chitin and chitosan from shrimp shell wastes

The 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 ...

Production of Chitin and Chitosan from Shrimp Shell in Batch Culture of Lactobacillus plantarum

Lactobacillus plantarum, as a potential lactic acid and protease producer, was used for biological extraction of chitin from shrimp shell. L. plantarum was grown in a batch culture containing shrimp shell powder and date syrup, incubated at 30 °C. The produced organic acids and proteases in L. plantarum culture were able to demineralize and deproteinize shrimp shell. Percentages of deproteiniza...

Production of Chitin and Chitosan from Partially Autolyzed Shrimp Shell Materials

The effect of partial autolysis during storage of shrimp biowaste on the quality of the extracted chitin and chitosan has been investigated. Shrimp waste materials were stored in a 30 o C incubator for 1-4 days. The quality of the chitin and chitosan extracted from these materials was assessed by ash and protein analysis and in solution by viscosimetry. Chitosan from fresh biowaste, treated for...

Improved Chitin and Chitosan Production from Black Tiger Shrimp Shells Using Salicylic Acid Pretreatment

Shrimp chitin and chitosan with improved characteristics were isolated from black tiger shrimp waste pretreated with 0.04 M Salicylic acid for ten hours. The pretreated shrimp shells could be efficiently demineralized and deproteinized at ambient temperature using 0.680 M HCl and 0.620 M NaOH, respectively. The duration of the treatments was 8 hours, the ash and protein residues in the final ch...
