The aim of this study was to investigate acute toxicity (96-hr LC50 and lethal concentrations) of waterborne metal mixture (Pb+Mn) for the fish, Catla catla, Labeo rohita, Cirrhina mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix. The extent of metals bio- accumulation in fish body organs viz. gills, liver, kidney, fins, bones, muscle and skin at both 96-hr LC50 and lethal conce...

In this work, peptides were extracted from Silver carp (SC) scales via protease hydrolysis and separated using two membranes (M1 M2). The results revealed that the water: SC scale ratios of 50.6 mL/g, alkaline 1 (AP1) dose 2313.6 U/mL, pH 8.14 optimal conditions, peptide yield reached 88.77 ± 0.32%. conditions separation clarified: operating pressure M1 (M2) was 0.25 (0.4) MPa, liquid temperatu...

Cystatins are proteins, which inhibit cysteine proteases, such as papain. In this study, the 336-bp cystatin C gene (family II, HmCysC) of silver carp (Hypophthalmichthys molitrix) was cloned and expressed in Escherichia coli BL21 (DE3). HmCysC encodes mature peptide (HmCystatin C), with 111 amino acids. A typical QXXXG motif found HmCystatin it formed a cluster Cyprinus carpio Danio rerio phyl...
