Abstrakt: The growth behaviour of Memnoniella echinata and Fusarium roseum was examined in slurry fermentation systems using untreated orange peel as substrate. A composite experiment was then designed to study the effect of orange peel initial concentration and the effect of the nitrogen: peel ratio on crude protein yidld ( Y) and protein enrichment ( Z) of the final biomass. The more concentrated the peel slurry, the greater the substrate inhibitory effect on microbial growth becomes. Finally, multiple regression technique allowed both the experimental values of Y and Z to be reconstructed with mean percentage errors smaller than 4% and 8%, respectively, and the optimal operating strategy for such SCP production process to be determined.
