The present invention provides a supplement composition and method of preparation thereof for cell culture. The supplement composition comprises natural substances without using any animal based serum. The present invention provides slaughter free, effective and affordable supplement for growth of animal cells that eliminates or minimizes dependency on the fetal bovine serum.

The present invention relates to virus growth media that improve the yield of alpha-herpesviruses (e.g., HSV-2) grown in cell cultures. The growth media of the invention include two additives, a disaccharide and a lipid mixture, that can be added to serum-free or serum-enriched growth media to improve the efficiency of virus production. The invention further provides methods of producing alpha-herpesviruses (e.g., HSV-2) in such growth media.

A product including plant-derived nanovesicles which induce differentiation of the stem cell sources into cartilage and bone cells is provided. The objective of the invention is to improve the rate of differentiation into cartilage and bone cells, enhance strength of the obtained tissue and to provide a non-toxic application with lower cost by means of giving plant exosomes in addition to the differentiation media to the adipose-derived stem cells.

The present invention relates to nutritional components suitable for cell culture of eukaryotic cells. These nutritional components can be prepared from plant-based protein hydrolysates. The invention further relates to nutrient media comprising these nutritional components. The nutrient media of the invention can be prepared by replacing serum components, which are common in such media, at least partiallyby the nutritional components of the invention. The nutritional components and the nutrient media of the invention are particularly suitable for use in the food industry, such as in the production of cultured meat.

A fermentation method for mupirocin, the method comprising performing shake flask seed culture, seed tank culture, fermentation culture, feed culture. The fermentation method is not only suitable for industrial mass production, but also improves the fermentation potency of mupirocin, which can be stably maintained to be 8000 ug/ml or above.

The invention discloses a method for preparing the ginsenoside preparation by biological engineering technology, wherein the ginsenoside preparation comprises at least one of the saponin-enriched preparation and the saponin-enriched syrup; the compound bio-enzyme preparation prepared by the combined bacteria preparation of yeast and lactic acid bacteria provided by the invention is rich in amino acid residues, amides, coenzymes and active groups such as lactic acid and linoleic acid; and the ginsenoside preparations containing ginsenosides can be prepared by adding monosaccharides or polysaccharides to the compound bio-enzyme preparations, providing new directions and ideas for obtaining ginsenosides and their products.

The present invention relates to a medium composition containing an Ecklonia cava extract for dedifferentiation into an induced pluripotent stem cell. Also, the present invention relates to a method for differentiating an induced pluripotent stem cell produced by using the medium composition into adipocytes.

A cell for treating neurodegenerative disease treated with angelica extract is provided. The pharmaceutical composition comprises the cell for treating neurodegenerative disease and can significantly increase and recover the number of dopaminergic neurons to achieve the goal for treating neurodegenerative disease.

The present invention relates to a medium composition for production of botulinum toxin and, more particularly, to a medium composition for culture of Clostridium sp. capable of producing botulinum toxin. The medium composition of the present invention comprises at least one plant-derived peptone selected from the group consisting of a garden pea hydrolysate, a cotton seed hydrolysate and a wheat gluten hydrolysate. When the medium according to the present invention, which contains plant-derived peptones and minerals, is used for culture of Clostridium botulinum, the growth rate of the bacterium in the medium is about 1.5-2 times higher than that in the medium that is in current use. In addition, when botulinum toxin is produced by culturing the bacterium in the medium, infection with transmissible spongiform encephalopathy (TSE) or the like can be prevented by blocking introduction of animal-derived components.

Disclosed are date palm compositions and methods of use of such compositions. Such compositions may be used as part of a growth medium for culture of microorganisms. In certain embodiments, date palm extracts of the disclosure are used as part a culture medium to grow Lactobacilli.
