Solid state fermentation of apple pomace for concomitant production of ethanol and animal feed.

The effect of solid state fermentation (SSF) of apple pomace using 3 yeasts or natural fermentation was studied. Yeast-inoculated fermentation produced more ethanol, CP and soluble proteins than natural fermentation. Ethanol production in natural fermentation was almost half than that of Saccharomyces cerevisiae-fermented pomace. The optimum time for ethanol production in SSF was 96 h. S. cerevisiae gave highest ethanol yields. Ethanol production by Candida and Torula was comparable. Combination of ammonium sulfate and zinc sulfate was detrimental to ethanol, CP and soluble protein production by natural microfloral and inoculated yeast fermentation. The natural microflora also responded better to ammonium sulfate than the addition of ammonium sulfate in combination with zinc sulfate.
