This article complements an earlier work published in 2015 Baron et al. (2015) that showed the interest of a shrimp shells bio-refining process. We compare here the effect of eleven commercial proteases at pH 3.5 or 4.0 on a residual amount of shrimp shells proteins after 6 h at 50 °C. The two pH are obtained when respectively 40 and 25 mmol of formic acid are added to 5 g of mild dried shell. ...

BACKGROUND There is concern that shrimp-allergic individuals may react to glucosamine-containing products as shrimp shells are a major source of glucosamine used for human consumption. OBJECTIVE The purpose of this study was to determine whether shrimp-allergic individuals can tolerate therapeutic doses of glucosamine. METHODS Subjects with a history of shrimp allergy were recruited and tes...

With a growing population, changes in consumerism behavior and trends consumption Indo-Pacific Asia, our seafood processing practices produce large volume of waste products. There are several advantages regulating sustaining shellfish industries. The major advantage management is that it leads to better conservation natural resources the long run. Shrimp shell contains useful biomaterials, whic...

Penaeidins are members of a new family of antimicrobial peptides isolated from a crustacean, which present both Gram-positive antibacterial and antifungal activities. We have studied the localization of synthesis and storage of penaeidins in the shrimp Penaeus vannamei. The distribution of penaeidin transcripts and peptides in various tissues reveals that penaeidins are constitutively synthesiz...

Chitosan was prepared from shrimp processing waste (shell) using the same chemical process as described for the other crustacean species with minor modification in the treatment condition. The physicochemical properties, molecular weight (165394g/mole), degree of deacetylation (75%), ash content as well as yield (15%) of prepared chitosan indicated that shrimp processing waste (shell) are a goo...

Dispersions of colloidal particles in aqueous media are widely investigated because of their use in many industrial applications (foods, pharmaceuticals, cosmetics, paints, etc.). Acid-hydrolyzed chitin has been reported to spontaneously disperse into colloidal rod-like crystalline particles, which can form rigid structures. Such colloidal dispersions of acid-degraded chitin can undergo an isot...

The wastes generated by the shrimp industry are approximately between 50 and 60% of catch volume. These residues such as head, viscera, shell potential pollutants if they not treated for proper disposal. One way to solve this problem is use functional food ingredients. In regard, rich in chitin, second most abundant biopolymer on planet after cellulose. Chitin composed N-acetyl glucosamine, a m...

Due to the limited reaction rate of oxygen reduction (ORR), it is considered as a limiting factor in performance fuel cells and metal-air batteries. Platinum benchmark catalyst for ORR; however, scarcity platinum, its high price, drift phenomenon, insufficient durability, susceptibility gas poisoning are reasons constant search new ORR catalysts. Carbon-based catalysts show exceptional promise ...

Seasonal plankton blooms correlate with occurrence of cholera in Bangladesh, although the mechanism of how dormant Vibrio cholerae, enduring interepidemic period in biofilms and plankton, initiates seasonal cholera is not fully understood. In this study, laboratory microcosms prepared with estuarine Mathbaria water (MW) samples supported active growth of toxigenic V. cholerae O1 up to 7 weeks a...

Three axiid species and one calocaridid are recorded from Taiwan. The three deepwater species are described as new: Calaxius manningi, having a finely pitted carapace and strongly spinose chelipeds; Calocarides chani, which possesses finely tuberculate first chelipeds; and Ambiaxius foveolatus, which has a shallowly pitted carapace branchiostegite. Neaxius acanthus (A. Milne Edwards) is recorde...
