The present invention provides a differentiation medium for differentiation and expansion of a multicellular aggregation in suspension derived from human pluripotent stem cells that has been induced to differentiate to an artificial tissue structure such as artificial neural tissue, said medium comprising a basal medium for animal or human cells, wherein said differentiation medium has a viscosity between 1.7 mPa*s and 1500 mPa*s. Said viscosity is achieved by the presence of a viscosity enhancer such as methyl cellulose, carboxymethyl cellulose, or hydroxy ethyl cellulose in said differentiation medium. Also disclosed are an in-vitro method for obtaining artificial neural tissue and a kit comprising said differentiation medium.

A microorganism of the present invention is Dirkmeia churashimaensis (NITE BP-03054), Papiliotrema flavescens (NITE BP-03051), Papiliotrema flavescens (NITE BP-03052), or Apiotrichum porosum (NITE BP-03053).

Methods and compositions for pre-conditioning, transduction and/or hypothermic preservation of vascular cells transduced with nucleic acid constructs for expressing pro-angiogenic factors are provided. Also provided are uses of such cells in therapy.

A medium supplement for high-yield culture of anaerobes is disclosed. The medium supplement includes N-acetylhexosamine, L-aspartic acid, L-cysteine and cobalamin. A culture medium including the supplement and a culture method using the culture medium are also disclosed. It is possible to provide an innovative method which is capable of achieving high-concentration culture of anaerobes that are difficult to culture in high yield. The method is cost-effective, and in particular, is capable of culturing large amounts of fastidious aerobes suitable for use in food and pharmaceutical applications.

Methods of producing a bio-stimulant by fermentation and methods of producing a fertilizer composition using the bio-stimulant are disclosed. Fertilizer compositions comprising the fermented bio-stimulant are also disclosed. The fermented bio-stimulant contains a plurality of microorganisms which originate from a natural environment such as the soil and humus of a thriving plant. In some embodiments, the fertilizer compositions comprise a carbon nanomaterial such as carbon nanotubes (CNTs).

Use of human milk oligosaccharide LNT, for increasing serpin protein production in Bifidobacterium longum subsp. longum.

The present invention relates to compositions comprising low sugar media, the methods of using these compositions to reduce trauma and stress on processed animal sperm, the resulting sperm and embryo products, and the methods of use of these products to increase the quality, quantity and viability of progeny and improved rates of births in animals.

The present invention relates to methods of modulating the mannose content of recombinant proteins.

Disclosed is a L-isoleucine-producing Corynebacterium glutamicum fermentation medium, comprising a basal medium and a growth factor, wherein the growth factor consists of choline, betaine and vitamin B6, and the contents of each ingredient in the fermentation medium are: 0.2-1 g/L choline, 0.25-0.5 mg/L betaine, and 0.05-0.3 mg/L vitamin B6. Also disclosed is a method for cultivating the L-isoleucine-producing Corynebacterium glutamicum, comprising: inoculating the L-isoleucine-producing Corynebacterium glutamicum onto the fermentation medium, wherein the volume of the bacteria liquid accounts for 5-20% of the volume of the fermentation medium, adjusting the pH to 6.5-7 with aqueous ammonia, controlling the dissolved oxygen to 30-50%, and fermenting for 25-30 h; then decreasing the dissolved oxygen to 15-25%, and feeding a 50-80% glucose solution into the fermentation broth to control the residual sugar at 3-4%, continuing the fermentation until 60-70 hours, then terminating the fermentation, and controlling the temperature of the overall fermentation process at 29-33° C.

The present invention relates to methods of upregulating the high mannose glycoform content of a recombinant protein during a mammalian cell culture by manipulating the mannose to total hexose ratio in the cell culture media formulation.
