The invention of a reactor for the production of growth factors to regenerate the epithelium of the auditory system from embryonic stem cells, aimed at stimulating sensory tissue to enhance hearing capacity, in the form of a lyophilized powder provides a novel reactor and method for producing growth factors that stimulate stem cells in the auditory region, promoting their conversion into auditory epithelial cells. The reactor comprises three sections: an upper transparent section for culture observation and sterilization via a UV lamp, a middle section for continuous mixing and purification using micro-filters, and a lower section for lyophilization. The reactor maintains optimal conditions for stem cell proliferation, utilizing controlled temperature and vacuum pressure to concentrate beneficial substances and crystallize growth factors into a lyophilized powder. This product serves as a potential treatment for auditory conditions, enhancing the regeneration of auditory structures and delaying the onset of presbycusis.

The present disclosure relates to a process for electrostatic spray drying of a living microorganism with a specific surface charge. using electrostatic charge provided by a high voltage source, wherein said electrostatic charge is the same as the surface charge of the microorganism.

Systems and methods for fractionating whole stillage from an ethanol production facility are provided. Whole stillage undergoes a separation of its liquid portion (thin stillage) from the solid portion (fiber cake). In some embodiments, the solids and liquids in whole stillage may be separated utilizing a screening centrifuge. The fiber cake may be dried to generate a high fiber animal feed. The thin stillage may be provided to a three-phase separator for separation into an oil emulsion, an aqueous clarified stillage, and a protein paste. The protein paste may be dried to generate a high protein animal feed with greater than about 45% protein content. The clarified thin stillage is condensed to yield a syrup with greater than around 60% solids. The oil emulsion is subjected to a pH adjustment to liberate the oil from the emulsion, which is then separated.
