Zusammenfassung:	Methods for propagation of yeast using cellulosic material as a carbon source are disclosed. A propagation medium is provided by combining a nutrient source, a cellulosic material to be used as a carbon source, enzymes that hydrolyze the cellulosic material into monosaccharides that can be taken up and metabolized by yeast, and a first cell mass of yeast. The propagation medium is incubated in a temperature range that allows the enzymes to break down the cellulosic material into monosaccharides at a rate that leads to production of a second cell mass of yeast, while keeping ethanol production low enough that the concentration of ethanol does not exceed 0.1 grams per liter of propagation medium.
