BACKGROUND Chitin, after cellulose the second most abundant polysaccharide in nature, is an essential component of exoskeletons of crabs, shrimps and insects and protects these organisms from harsh conditions in their environment. Unexpectedly, chitin has been found to activate innate immune cells and to elicit murine airway inflammation. The skin represents the outer barrier of the human host ...

Indonesia's shrimp industry is growing rapidly, but a surge in waste such as shells and heads shrimps are increasing well. These products contain important components protein, minerals, amino acids. This study aims to determine the chemical properties of liquid broth extracted from freshwater marine shells, including ash, fat, monosodium glutamate (MSG), antioxidant. The was by boiling water wi...

Clam shells are a food solid waste that increases and accumulates every day, causing environmental pollution. (Anadora granosa) contain chitin. Chitin can be processed into chitosan, which effective in absorbing heavy metals. To increase absorption, chitosan modified membrane. The purpose of this study was to analyze the membrane's ability from blood clam reduce levels iron water. design pure e...

Silver-exchanged zeolites and clays are used in polymer composites to confer broad-spectrum antimicrobial properties on a range of functional materials. Tobermorite is a layer lattice mineral whose potential as a carrier for Ag ions in antibacterial composites has not yet been investigated. Accordingly, in this study, synthetic tobermorite was ion-exchanged with 10 wt% silver ions and the resul...

Chitosan has been extracted from different marine crustacean from the Black Sea of Bulgarian Gulf. The contents of the various exoskeletons have been analyzed and the percent of the inorganic salt , protein, chitinand chitosan was determined. Deacetylation of the different chitin produced was conducted by the conventional thermal heating method. The chitosan was characterized by elemental analy...
