Summary
Solid state fermentation of dried citrus peel was studied in a packed bed reactor withAspergillus niger QH-2. When no nitrogen source was added the growth was limited. When urea and/or ammonium sulphate were added in the proportion of 0.63 g N/100 g solid dry substrate a diauxie was observed and the final content of crude protein was higher than 10%. The results of a factorial design show that ammonium sulphate has a significant effect on the specific growth rate.
