Abstract: The invention provides a method of increasing product yield per culture in a population of product-secreting cells bound to a scaffold, for example, a microcarrier, at least partially immersed in a culture medium in a bioreactor. The method comprising: semi-harvesting product by removing a volume of the culture medium with a first-secreted product concentration while leaving the scaffold with the bound cells in the bioreactor; re-feeding the cells by adding a fresh culture medium to increase the culture medium in the bioreactor to approximately the original volume; agitating the culture medium to allow the cells to grow and release a second-secreted product concentration; harvesting product by removing the culture medium with the second-secreted product concentration while leaving the scaffold with the bound cells behind. Also disclosed is a method of increasing virus yield per culture in a population of virus-infected cells bound to a microcarrier suspended in a culture medium.

Abstract: The invention provides a an inactive, non-replicating vaccine comprising whole virion, chemically inactivated Yellow Fever virus which is inactivated using a method that ensures preservation of critical, neutralizing epitopes. The Yellow Fever virus has been adapted to propagate in cells to higher yields than the unadapted virus. The invention also provides methods for preventing Yellow Fever viral infection.

Abstract: Disclosed herein is a system and method for condensing moisture in a moist gas stream entering a bioreactor or leaving a bioreactor, forming a dry gas stream for entering or leaving the bioreactor.

Abstract: A single-use, single or multiple tissue, organ, and graft bioreactor and environmental control system is designed to replicate the necessary conditions for growth of tissues, organs, or grafts, while addressing problems in scaling up the tissue growth; adaptation to a single-use or disposable format; and operation as a stand-alone unit that provides full environmental control of cell culture conditions.

Abstract: Disclosed is a method of increasing product yield per culture in a population of bound product-secreting cells in a bioreactor, the method comprising: semi-harvesting product by removing a volume of the culture medium with a first-secreted product concentration; re-feeding the bound population of product-secreting cells by adding an amount of a fresh culture medium sufficient to increase the volume of the culture medium to approximately the original volume of the culture medium; agitating the culture medium under sufficient conditions and for a sufficient time period to allow the bound population of product-secreting cells to grow and to release a second-secreted product concentration into the culture medium; and harvesting product.

Abstract: Methods are provided for producing serum-free, animal cell culture media which have enhanced cell culture properties, such as cell growth, cell viability and protein production properties. The cell culture properties of standard serum-free media formulations, which include compositions such as inorganic salts, glucose, fatty acids, amino acids and vitamins, can be enhanced according to the methods of the invention, by providing the media with an additive. The additive in one embodiment can be produced by the acid or base catalyzed hydrolysis of a phosphoglyceride.
