This gives the sugar overall recovery of 10 %. A niger posseses an array of extracellular enzymes for long chain carbohydrates including cellulase, xylanase, amylase, and glucoamylase [13]. The low recovery may be due to the limitation in the enzymes activity in this solid state fermentation. While it is less expensive, the solid state fermentation technique has a drawback of a low substrate and metabolite transport.
