three hundred and sixty broiler chicks (ross 308) were employed in an experiment from 6 to 49 days of age to evaluate the effect of replacing canola meal for soybean meal either with or without enzyme supplementation. dietary treatments included 5 substitution levels (0, 25, 50, 75 and 100%) at two enzyme concentrations of: 0 and 400 g/ton in a 5×2 factorial layout experiment. the enzyme mixtur...
the protease enzyme breaks down protein into amino acids as its constructors. protease immobilization onto appropriate support materials plays an essential role in various fields of technology including the food and detergent industries. accordingly, improvement of protease immobilization has been highly regarded due to its applications in bio catalysis. alginate and chitosan are natural polysa...
Abstract Background and Objective: Recognizing and using of isolated phytase in the soil microorganisms are paramount importance to produce the Phytase enzyme utilized commercially in different industries. This study was conducted to recognize different bacillus species which are Phytase producers and detection of the gene that can produce this enzyme. Material and Methods: Soil samples were...
introduction: hydatid cyst disease is caused by the protoscolices of echinococcus granulosus. alkaline phosphatase (alp) enzyme is required for metabolism, physiology, immunology, and nutrients absorption in parasite. the aim of this study was to compare the level of alp activity (as a pathological biomarker) in hydatid cyst protoscolices (hcp) with that of sheep liver tissue and to determine t...
fumigant toxicity of rosemary essential oil on abamectin-resistant vs. susceptible populations of two spotted spider mites, tetranychus urticae koch was studied under laboratory conditions. results indicated that fumigant toxicity of rosemary essential oil on the susceptible population was 3.06 times higher than that of the resistant one. accordingly, there was a slight cross resistance observe...
Background: Diabetes is a metabolic abnormality in the body caused by the high activity of the α-glucosidase enzyme in the hydrolysis of carbohydrates to glucose. Alpha-glucosidase inhibitors involved in the digestion of carbohydrates, play a key role in controlling diabetes. Thymus vulgaris is a species of flowering plant in the mint family Lamiaceae with a chromosome number of 2n = 30. The es...
aacel9a [β-1,4-endoglucanase, (e.c:3.2.1.4)], was immobilized onto glutaraldehyde activated chitosan macrosphere by covalent attachment. the properties of the immobilized aacel9a were investigated by determining the optimum ph and optimum temperature for activity, thermal stability, and kinetic parameters. the immobilization process shifted the enzyme’s optimum temperature from 65 °c for the fr...
Introduction: To determine an indicator for Triclabendazole (TCBZ) efficacy, Alanine aminotransferase (ALT) activity in Fasciola hepatica (Iranian isolate) parasite in presence and absence of TCBZ was evaluated by an in vitro cultivation method. Also, ALT enzyme activity between none and parasitized-infected sheep liver tissues was assessed. Method: The sheep livers were collected and tra...
Introduction: Glucose-6-phosphate dehydrogenase deficiency is the most common enzyme disorder. This enzyme involved in maintaining the balance of active oxygen species and its defect causes oxidative damage. PON1 is an HDL-based glycosylated protein that prevents lipid peroxidation. In this study, the prevalence of PON L55M polymorphism in paraoxonase enzyme in neonates with a deficiency in G6P...
Despite the availability of various alkaline phosphatase (ALP) isoenzymes, the calf enzyme is being used in current enzyme assays as the detector enzyme. The glycosylation pattern of this enzyme makes it a suitable ligand for binding to wheat germ agglutinin lectin (WGA). As a result of this property, the enzyme can not be used as a conjugate with this lectin, and the calf enzyme conjugates can...
