methods and systems for the propagation of a microorganism using a residual by-product of a cellulose and / or paper mill, and related methods and systems

摘要

the present invention relates to the use of a source of one or more monosaccharides derived from a residual paper or cellulose by-product for the propagation of microorganisms (for example, yeast or bacteria). if desired, after propagation, the microorganisms can then be used to ferment one or more monosaccharides derived from a residual by-product of a cellulose or paper mill into one or more biochemicals. optionally, a wort composition can be included in the propagation medium to facilitate propagation and / or a wort composition can be used to facilitate enzymatic hydrolysis of oligosaccharides and / or polysaccharides in a residual by-product of a pulp or paper mill form monosaccharides.
