Process of Using a Fish Plasma Component in a Nutrient Medium for Cell Culture
20230123857 · 2023-04-20 · ·

A process of using a fish plasma component in a nutrient medium for cell culture includes obtaining a fish that is a progeny of domesticated broodstock that are reared under consistent and reproducible conditions. Blood is obtained from the fish, and plasma is separated from the blood. One or more specific components of the plasma are then extracted, and cells are cultured in a nutrient medium using the one or more extracted plasma components, and none of any remainder of the plasma. The plasma and/or the plasma components is/are tested for presence and/or level of endotoxin. Extracting the one or more specific components of the plasma, and/or culturing the cells is only performed if the testing indicates an endotoxin level below a predetermined threshold. The cells cultured using the extracted one or more plasma components are other than fish cells.

Composition comprising lactic acid bacteria improved in intestinal adherence by coating with silk fibroin

The present invention relates to a method for improving lactic acid bacteria in survival rate, storage stability, resistance to acid or bile, and adherence to intestinal epithelial cells by coating the surface of lactic acid bacteria with silk fibroin, and a lactic acid bacteria composition prepared therethrough. Conventional techniques construct only a physical protective barrier outside a lactic acid bacteria body by multi-stage coating and thus retain the limitation of being unable to identify an effect on the coherence of lactic acid bacteria to intestinal epithelial cells upon the uptake of the lactic acid bacteria. In contrast, the present invention provides a method in which lactic acid bacteria is coated with silk fibroin extracted from cocoons, whereby the lactic acid bacteria is improved in stability under a storage and distribution condition as well as having remarkably increased stability and intestinal adherence particularly under an intestinal environment.
