title: Effects of inoculum size on solid-phase fermentation of fodder beets for fuel ethanol production.
abstract: This fuel ethanol study examined the effects of Saccharomyces cerevisiae inoculum size on solid-phase fermentation of fodder beet pulp. A 5% inoculum (wt/wt) resulted in rapid yeast and ethanol (9.1% [vol/vol]) production. Higher inocula showed no advantages. Lower inocula resulted in lowered final yeast populations and increased fermentation times.
