Production of iron-chelating proteinous hydrolysate from freshwater prawn, Macrobrachium nipponense
In this study, freshly harvested prawn, Macrobrachium nipponense were hydrolyzed with pepsin to develop a food ingredient and iron supplement. The degree of hydrolysis, protein/peptide concentration and iron-chelating capacity were verified by TCA soluble assay, direct UV spectrophotometric method and orthophenanthroline-based colorimetric assay, respectively. The result of TCA soluble assay re...
متن کاملMolecular Cloning, Characterization, and mRNA Expression of Hemocyanin Subunit in Oriental River Prawn Macrobrachium nipponense
Hemocyanin is a copper-containing protein with immune function against disease. In this study, a hemocyanin subunit named MnHc-1 was cloned from Macrobrachium nipponense. The full-length cDNA of MnHc-1 was 2,163 bp with a 2,028-bp open reading frame (ORF) encoding a polypeptide of 675 amino acids. The MnHc-1 mRNA was expressed in the hepatopancreas, gill, hemocytes, intestine, ovary, and stomac...
متن کاملcDNA Cloning and Expression Analysis of Gustavus Gene in the Oriental River Prawn Macrobrachium nipponense
The gustavus gene is required for localizing pole plasm and specifying germ cells. Research on gustavus gene expression will advance our understanding of the biological function of gustavus in animals. A cDNA encoding gustavus protein was identified and termed MnGus in the oriental river prawn Macrobrachium nipponense. Bioinformatic analyses showed that this gene encoded a protein of 262 amino ...
متن کاملPopulation Structure and Historical Demography of the Oriental River Prawn (Macrobrachium nipponense) in Taiwan
The oriental river prawn (Macrobrachium nipponense) is a non-obligatory amphidromous prawn, and it has a wide distribution covering almost the entire Taiwan. Mitochondrial DNA fragment sequences of the cytochrome oxidase subunit I (COI) and 16S rRNA were combined and used to elucidate the population structure and historical demography of oriental river prawn in Taiwan. A total of 202 individual...
متن کاملGenetic diversity analysis of oriental river prawn, Macrobrachium nipponense, in Yellow River using microsatellite marker.
To assess the genetic status of this species, the genetic diversity of wild Macrobrachium nipponense from seven geographic locations in the Yellow River basin were investigated using 20 polymorphic microsatellite DNA loci. The genetic diversity between populations was indicated by the mean number of alleles per locus and mean observed heterozygosity (H) and the expected H, which was arranged fr...
