The current study aims to produce ω- 3 PUFAs, by solid- state fungal fermentation, on barley spent grain, a by-product of the brewing industry and a food- grade waste. The substrate has a high protein content and a high fat content (21-25% and 9- 10% respectively on a dry basis). The enzymes used by the fungi to produce ω-3 PUFAs convert α- linolenic acid (ALA) into EPA.In this study, the substrate was supplemented with linseed oil (containing approximately 60% ALA) to determine the effect of ALA on growth and PUFA productionenPolyunsaturated fattyEicosapentaenoic acidBarley spent grainProduction of eicosapentaenoic acid by mortierella spp on barley spent grainConference PresentationJacobs, A., Du Plessis, L., Nxumalo, N., & Combrink, A.
