Summary
The suitability of three ascomycetous fungi, Aspergillus niger, A. awamori and Trichoderma reesei, as well as two basidiomycetes, Pleurotus ostreatus and Phanerochaete chrysosporium, for bioconversion of apple distillery slop was compared. Trichoderma and Phanerochaete degraded raw fiberes by 20%, producing filter cakes with 17% to 22% raw protein contents. Aspergillus spp. were superior in filtration time and COD reduction and were of the same efficiency in protein synthesis as Trichoderma and Phanerochaete, but did not degrade fibres. Pleurotus ostreatus did not degrade lignin under fermentation conditions used and could not compete with other fungi due to its slower growth.
