Abstract:
Amyloglucosidase (AMG) was produced by Aspergillus niger in solid-state fermentation (SSF), submerged fermentation (SmF) and an aqueous, two-phase system of polyethyleneglycol (PEG) and salt. In SSF, a fed-batch mode of operation gave a yield of 64 U/ml compared with 44 U/ml in batch mode. Similar trends were observed for SmF, where fed-batch cultivation gave a yield of 102 U/ml compared with 66 U/ml in batch. Shorter cultivation times (66 h) were required for SmF than for SSF (96 h). In the aqueous, two-phase cultivation, the productivity and yield of AMG were both twice those in the control fermentation.
