METHODS AND SYSTEMS FOR PROPAGATION OF A MICROORGANISM USING A PULP MILL AND/OR A PAPER MILL WASTE BY-PRODUCT, AND RELATED METHODS AND SYSTEMS

摘要

The present disclosure relates to using a source of one or more monosaccharides derived from a pulp or paper mill waste by-product for propagating microorganisms (e.g., yeast or bacteria). If desired, after propagation, the microorganisms can then be used to ferment one or more monosaccharides derived from a pulp or paper mill waste by-product into one or more biochemicals. Optionally, a stillage composition can be included in propagation medium to facilitate propagation and/or a stillage composition can be used to facilitate enzymatic hydrolysis of oligosaccharides and/or polysaccharides in a pulp or paper mill waste by-product to form monosaccharides.
