✦ Synopsis

Typical samples of the solid waste (50% moisture) from olive oil processing were subjected, after an alkaline pretreatment, to deligni®cation by Phanerochaete chryosporium, Phlebia radiata, Pleurotus ostreatus or Dacrymyces stellatus. The fermented material was then sacchari®ed by Trichoderma spp to provide a substrate for the yeasts, Candida utilis or Saccharomyces cerevisiae. Success was judged by the level of crude protein generated, and a combination fermentation involving Phan chryosporium, T reesei and S cerevisiae increased the level of crude protein from 5.9% in the raw pomace to 40.3% in the fermented material. It is suggested that this solid-state fermentation process could be used to manufacture an animal feed for the poultry industry in Jordan.
