Table 5 Characterizations of the commercial enzymes used in this study

From: Single-step ethanol production from raw cassava starch using a combination of raw starch hydrolysis and fermentation, scale-up from 5-L laboratory and 200-L pilot plant to 3000-L industrial fermenters

Commercial enzymes (types)

Optimum temperature (°C)

Optimum pH

Activity

StargenTM002 (blend of alpha-amylase and glucoamylase)

20–40

4.0–4.5

570 GAU/g

Distillase ASP (blend of glucoamylase and pullulanase)

58–65

4.0–4.5

580 GAU/g

  1. GAU/g means glucoamylase unit (GAU). One GAU unit, defined by DuPont, is the amount of enzyme that will liberate 1 g of reducing sugars calculated as glucose per hour from soluble starch substrate under the assay conditions
