The enzyme combination with the
highest release of reducing sugar was (g) Ternamyl 0.24
KNU + Viscozyme 24 FBGU + Celluclast 2% with a rate of
18.48 g L1 that corresponded to 0.92 g released sugar per g of
raw dry PPW.
Using this combination, at the end of fermentation
the reducing sugars were 1.93 g L1. Therefore, the sugars consumed
were 16.55 g L1 (Table 2). In all treatments the non-fermented
sugar at the end of fermentation was very low. The
consumed sugar during fermentation was very high (up to 89%),
indicating the high ability of S. cerevisiae var. bayanus to bioconvert
reducing sugars.
