Formulation and Evaluation of Solid Dispersion Chitosan Tablet from Whiteleg Shrimp (Litopenaeus vannamei) Using PVP K-30 As a Carriers

Probiotics in Larvae and Juvenile Whiteleg Shrimp Litopenaeus vannamei

Purification and characterization of an intracellular lipase from pleopods of whiteleg shrimp (Litopenaeus vannamei).

An intracellular lipase present in the whiteleg shrimp Litopenaeus vannamei was detected in pleopods. The lipase from pleopods was purified and characterized by biochemical and kinetic parameters. Purified intracellular lipase has a molecular mass of 196kDa, the polypeptide is assembled by two monomers, 95.26 and 63.36kDa. The enzyme lacks glycosylation, and it has an isoelectric point of 5.0. ...

Analysis of multiple tissue-specific cDNA libraries from the Pacific whiteleg shrimp, Litopenaeus vannamei.

Multiple small-scale transcriptome studies have been undertaken for various members of the Penaeidae. Penaeid shrimp are important both as members of diverse ecosystems around the world and for their importance as commercial commodities. Of the many shrimps, the most important from this family is the Pacific whiteleg shrimp, Litopenaeus vannamei, as it is the primary shrimp used in worldwide aq...

Carbohydrate Moieties and Cytoenzymatic Characterization of Hemocytes in Whiteleg Shrimp Litopenaeus vannamei

Hemocytes represent one of the most important defense mechanisms against foreign material in Crustacea and are also involved in a variety of other physiological responses. Fluorescent lectin-binding assays and cytochemical reactions were used to identify specificity and distribution of carbohydrate moieties and presence of several hydrolytic enzymes, in hemocytes of whiteleg shrimp Litopenaeus ...

Transcriptomic responses of juvenile Pacific whiteleg shrimp, Litopenaeus vannamei, to hypoxia and hypercapnic hypoxia.

Estuarine crustaceans are often exposed to low dissolved O2 (hypoxia) accompanied by elevated CO2 (hypercapnia), which lowers water pH. Acclimatory responses to hypoxia have been widely characterized; responses to hypercapnia in combination with hypoxia (hypercapnic hypoxia) are less well known. Here we used oligonucleotide microarrays to characterize changes in global gene expression in the he...
