Solid-substrate fermentation ofKloeckera apiculata andCandida utilis on apple pomace to produce an improved stock-feed
- 95 Downloads
Apple pomace was used in solid-substrate fermentation with the yeastsKloeckera apiculata orCandida utilis Y15. A total crude protein content of 7.5% (w/w) was achieved after 72 h for each yeast. The concentration of essential amino acids in the modified apple pomace was more than twice that in the control, enhancing its nutritive value as a stock-feed supplement. The fermentation of pomace as described can be used to reprocess this waste material into a useful value-added product for the agricultural sector.
