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...
متن کاملFermented and enzymatic production of chitin/chitosan oligosaccharides by extracellular chitinases from Bacillus cereus TKU027.
Two chitinases, Chi I and Chi II, were purified from the culture supernatant of Bacillus cereus TKU027 with shrimp head powder (SHP) as the sole carbon/nitrogen source. The molecular masses of Chi I and Chi II determined using SDS-PAGE were approximately 65kDa and 63kDa, respectively. Chi I toward various surfactants showed high stability, such as SDS, Tween 20, Tween 40 and Triton X-100, and t...
متن کاملProduction 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...
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 کاملPrebiotic oligosaccharides in premature infants.
OBJECTIVE The aim of the study was to determine the impact of increasing doses of 2 prebiotic oligosaccharides and of an "all-human diet" on the intestinal microbiota of premature infants. METHODS Twelve premature infants receiving formula feedings were randomly assigned to receive either galacto-oligosaccharide (F+GOS) or a pooled concentrated donor human milk product containing human milk o...
