Abstract Actinomycetes, as the main producers of a variety active metabolites and enzymes, have received extensive attention in aquaculture. An actinomycete had been isolated from Haizhou Bay identified by morphological analysis 16S rRNA sequencing. Results showed that highest similarity (99.65%) with Nocardiopsis sp. was named strain E10. Strain E10 produced an exo-enzyme proteinase effect str...

The function of algae extract (AE) in fishmeal (FM) substitution with plant proteins the diets Gibel carp (Carrassius auratus gibeilo) was investigated during a 56-day trial. Diets 1 and 2 contained 10% FM, 3 4 5% Diet 5 6 0% FM. In contrast, 2, 4, were supplemented 0.2% AE. results showed that FM reduction inhibited growth performance, while AE supplementation alleviated inhibition. significan...

Schizophyllum commune is a basidiomycete that capable of producing different valuable metabolites such as schizophyllan-a polysaccharide, ethanol, and lignocellulolytic enzymes. Schizophyllan finds application in the food industry, pharmacy, oil recovery. It acts non-specific stimulator immune system. shows bioactivities antineoplastic, antibacterial, anti-cancer, anti-inflammatory, antiparasit...

Glutamine is an important amino acid for immune function. Though high intensity and prolonged exercise decreases plasma glutamine concentration and causes immune suppression, the relationship between neutrophil functions and glutamine has not yet been found. The purpose of this study was to investigate the impacts of glutamine supplementation on neutrophil function. Twenty-six male university j...

Leukocyte extravasation from the blood into tissues is crucial for normal immune surveillance and in inflammation. Traditionally molecules belonging to selectin, chemokine, integrin, and immunoglobulin super families are thought to mediate the multiple adhesive and activation events needed for a successful emigration cascade. Recently, emerging evidence suggests that enzymes expressed on the su...

Site-directed mutagenesis (SDM) as a powerful technique was used to change two important and conserved amino acids in 5-enolpyruvylshikimate 3- phosphate synthase (EPSPS) gene of E. coli. The mutations changed glycine 96 to alanine and alanine 183 to threonine. These two amino acids are very important for intraction of the wide spectrum herbicide, glyphosate, to EPSP synthase enzymes. By design...
