Abstract: Processes for extracting and recovering nutrients from organic wastes to create a cell culture broth for microorganisms involve the main steps of mixing, solid/liquid separation, optimization, and sterilization. In an embodiment, the method for converting organic waste material into a cell culture broth or growth media includes: (a) mixing an organic waste material with one or more solvent to create a mixture of liquids and solids under substantially turbulent conditions; (b) separating the mixture of liquids and solids into a liquid stream and solid stream; and (c) sterilizing the liquid stream, whereby the cell culture broth or growth media comprises the sterilized liquid stream.
