The present invention relates to the field of fermentation biotechnology, more particularly to methods for the fermentative production of massoia lactone by Aureobasidium species.

In accordance with the present invention, CHO cells expressing a recombinant polypeptide of interest are grown in media where the amino acids, vitamins, phosphate, lipids and/or antioxidant optimization is utilized to manipulate and/or control the protein quality attributes of the polypeptides. Polypeptides expressed in accordance with the present invention may be advantageously used in the preparation of pharmaceutical compositions.

A culture for the fermentative production of Massoia lactone comprising an Aureobasidium melanogenum species in a culture medium, wherein the Aureobasidium melanogenum species expresses no functional Aureobasidin A synthase gene mRNA when cultured, the culture medium including KH.sub.2PO.sub.4, Na.sub.2HPO.sub.4, (NH.sub.4).sub.2SO.sub.4, MgSO.sub.4.Math.7H.sub.2O and CaCl.sub.2.Math.2H.sub.2O; at least two trace elements selected from the group consisting of Fe.sup.2+, Cu.sup.2+, Zn.sup.2+ and MoO.sub.4.sup.2−; urea; and a carbon source selected from the group consisting of glucose, mannose, xylose and mixtures thereof, wherein the culture medium has a pH from 5.5 to 6.5.

The present invention provides isolated polypeptides isolatable from a Fusobacterium spp. Also provided by the present invention are compositions that include one or more of the polypeptides, and methods for making and methods for using the polypeptides.

A pomegranate molasses medium for culturing microbes includes a mixture of pomegranate molasses, soil extract, and water. The pomegranate molasses medium for culturing microbes may optionally include at least one of potassium dihydrogen phosphate and iron ammonium EDTA. At least one beneficial microbe may be cultured on the pomegranate molasses medium. The at least one beneficial microbe may include, e.g., Cyanothece and/or beneficial fungus.

Provided herein are recombinant lentiviral vectors and methods of using the same to produce genetically modified keratinocytes that can be maintained in culture for over 100 population doubling without loss of morphological features or differentiation capacity. Immortalized keratinocytes and immortalized cell lines obtained by the methods of this disclosure are useful for studying the role of pathogenic mutations in skin disease phenotype, for screening for potential therapeutic agents, and for producing race-, sex, and age-specific epidermis for research and clinical applications.

The present invention provides isolated polypeptides isolatable from a Fusobacterium spp. Also provided by the present invention are compositions that include one or more of the polypeptides, and methods for making and methods for using the polypeptides.

Disclosed is a cell culture medium for cultivating cells, containing an iron-citrate-diphosphate complex as an iron source. Also disclosed is a method for cultivating cells, one or more cells being replicated or maintained in the cell culture medium and to a method for expressing at least one recombinant protein in a cell culture, a nucleic acid being introduced into the cell replicated or maintained in the cell culture medium, wherein the nucleic acid causes the production of at least one recombinant protein. The cell culture medium is advantageous in that the iron source contained therein dissolves very efficiently and rapidly in an aqueous solution, can be efficiently imported into the interior of the cells, causes an increased cell viability and an increased product titer during the production of recombinant proteins, and is very inexpensive.

As a technology for enriching atrial myocytes or ventricular myocytes in a cardiomyocyte-containing cell population induced from stem cells, provided is a method for enriching atrial myocytes or ventricular myocytes in a cardiomyocyte-containing cell population induced from stem cells, the method including a step of collecting atrial myocytes or ventricular myocytes from the cell population by using the expression level of CD151 as an index.

The specification describes an improved serum-free animal cell culture medium, which can used for the production of a protein of interest. Ornithine, or a combination of ornithine and putrescine can be added to serum-free media or chemically defined media to improve viable cell density, to reduce cell doubling time, and to increase the production of a protein of interest.
