Due to the fact that some individuals are allergic to crustaceans, the presumed relationship between allergy and the presence of chitin in crustaceans has been investigated. In vivo, chitin is part of complex structures with other organic and inorganic compounds: in arthropods chitin is covalently linked to proteins and tanned by quinones, in fungi it is covalently linked to glucans, while in b...

Shrimp residues generated by the seafood industrial processing are generally discarded in environment without any further treatment, leading to a loss of nutritional value such as proteins, lipids, chitin, carotenoids, and minerals. This practice can lead environmental problems due decomposition these substances air. The objective this study was extract astaxanthin-rich materials from shrimp (L...

Shrimp shell waste are potential to be processed further into value-added products, such as N-acetylglucosamine (GlcNAc). In the production of GlcNAc, biological approach is preferred and environmentally friendly chemical treatment. Chitinase an enzyme that plays a vital role in bioprocessing shrimp GlcNAc. Previously, Bacillus cereus SMG 1.1 was isolated from fermented paste (terasi) showed ab...

Chitosan is a chitin-derived fiber, extracted from the shellfish shells, by-product of fish industry, or fungi grown in bioreactors. In oenology, it used for control Brettanomyces spp., prevention ferric, copper, and protein casse clarification. The International Organisation Vine Wine established exclusive utilization fungal chitosan to avoid eventuality allergic reactions. This work focuses o...

Marine pollution has increased in recent decades, largely due to the proliferation of seafood processing plants and improper disposal their associated waste streams. The streams consist mainly shells that are composed chitin, which is most abundant aminopolysaccharide biopolymer nature. Recognizing value potential for valorization crustacean chitin production was explored. In this regard, bioge...

Chitin was first discovered by its name from the Greek word “chiton”, which means “mail coat”. It is indeed a polysaccharide made up of naturally occurring acetyl-D-glucosamine monomers. Hatchett researcher who extracted chitin shells mollusks (crabs and lobsters), prawns, crayfish in 1799. Later 1811, Henri Braconnot cell walls mushrooms called it “fungine”. chitosan are abundant biosphere as ...

The use of porous ceramic filters is promoted globally for household water treatment, but these filters are ineffective in removing viruses from water. In order to increase virus removal, we combine a promising natural coagulant, chitosan, as a pretreatment for ceramic water filters (CWFs) and evaluate the performance of this dual barrier water treatment system. Chitosan is a non-toxic and biod...

BACKGROUND Most of the current colorimetric methods for detection of chitinase or cellulase activities on the insoluble natural polymers chitin and cellulose depend on a chemical redox reaction. The reaction involves the reducing ends of the hydrolytic products. The Schales' procedure and the 3,5-dinitrosalicylic acid (DNS) method are two examples that are commonly used. However, these methods ...
