Two peptides with antioxidant activity were isolated from Pseudosciaena crocea proteins. Pseudosciaena crocea muscle was hydrolyzed with neutral protease to obtain Pseudosciaena crocea protein hydrolysates (PCPH). After ultrafiltration through molecular weight cut-off membranes of 10, 5 and 3 kDa and assessment of free radical scavenging ability, the fraction (PCPH-IV) with the highest antioxid...

In order to investigate the immune role of ribosomal protein L10 (RPL10/QM-like gene) in marine fish, we challenged the large yellow croaker Pseudosciaena (= Larimichthys) crocea, the most important marine fish culture species in China, by injection with a mixture of the bacteria Vibrio harveyi and V. parahaemolyticus (3:1 in volume). Microarray analysis and real-time PCR were performed 24 and ...

Shewanella and Pseudomonas are considered to be the main spoilage bacteria for chilled fish. This work focused on adhesion ability of two (Shewanella spp. S-1 P-1), inhibitory effects Bacillus subtilis against in large yellow croaker (Pseudosciaena crocea). We aimed develop a feasible solution prolong shelf life croaker. The characteristics strains were compared. It was found that induced more ...

Peroxiredoxins (Prxs) are thiol-specific antioxidant proteins that exhibit peroxidase and peroxynitrite reductase activities involved in the reduction of reactive oxygen species. The peroxiredoxin Prx4 from the large yellow croaker Pseudosciaena crocea is a typical 2-Cys Prx with an N-terminal signal peptide. We solved the crystal structure of Prx4 at 1.90 Å and revealed an N-terminal antiparal...

Although the single-cell gel electrophoresis (SCGE) alkaline comet assay can detect DNA damage quickly and with high sensitivity, it does not work well for cryopreserved sperm of some marine teleosts. Using large yellow croaker Pseudosciaena crocea sperm that were cryopreserved in increasing concentrations (5 to 30%) of DMSO, we made modifications to the classic SCGE method that included using ...

The objective of this study was to investigate the effect of conjugated linoleic acids (CLA) in artificial feeds on the growth and quality of large yellow croaker (Pseudosciaena crocea) raised in cages. Two diet formulas with dietary CLA were developed, and a diet without of CLA served as a control. The effects of CLA (2% and 4%) on average daily gain per tail (DGT), feed conversion ratio (FCR)...

This paper investigated the effect of freezing methods on moisture distribution, freshness, protein properties, and microstructure large yellow croaker (Pseudosciaena crocea) during frozen (?18°C) storage. The include, refrigerator (RF), plate (PF), spiral (SF), immersion (IF), liquid nitrogen (NF). results showed that RF took longest time, 587.3 min, rate PF, SF, IF NF was more than ten times ...
