摘要：

Three Aspergillus niger strains were grown in submerged and solid state fermentation systems with sucrose at 100 g l(-1). Average measurements of all strains, liquid vs solid were: final biomass (g l(-1)), 11 +/- 0.3 vs 34 +/- 5; maximal enzyme titres (U l(-1)) 1180 +/- 138 vs 3663 +/- 732; enzyme productivity (U l(-1) h(-1)) 20 +/- 2 vs 87 +/- 33 and enzyme yields (U/gX) 128 +/- 24 vs 138 +/- 72. Hence, better productivity in solid-state was due to a better mould growth.
