BioConvert – ACGA (Glucoamylase Enzyme for Bio-ethanol)


BioConvert – ACGA is a fungal Glucoamylase enzyme derived from a selected strain of Aspergillus niger. The enzyme is a 1, 4- alpha-D-glucan glucohydrolase (E.C. and is commonly referred to as Glucoamylase or Amyloglucosidase. It is an exoamylase that catalyzes the release of successive glucose units from non-reducing ends of dextrin and oligosaccharides chain by hydrolyzing both linear (1, 4-+-D) and branched (1, 6-+-D) glucosidic linkages. BioConvert – ACGA is used to saccharify liquefied starch from various sources such as corn, wheat, milo, sorghum, tapioca, barley, rice & potatoes. The resultant products are glucose rich syrups.

The below laboratory data provides plant operating guidelines for time, temperature & pH. Each parameter may be varied within a plant to achieve the target level at minimum operating cost.

Temperature and pH profile of BioConvert – ACGA:
The relative Glucoamylase activity of BioConvert – ACGA as a function of pH for 1 hour at 60° C in 4% w/v soluble starch shows optimum pH range of 4.0 to 4.4 and the operating range of 3.5 to 5.5. The relative Gluco Amylase activity of BioConvert – ACGA incubated for 1 hour at pH 4.4 in 4% w/v soluble starch shows optimum temperature range of 58° to 65° C.

The activity can be customized according to performance requirements or current use.

In a typical sacharification at 60° C, pH 4.3 and with a holding time from 24 to 72 hours, the enzyme dosage is 0.35 to 1 Kg of BioConvert – ACGA enzyme per metric ton of starch dry substance.

It is available in 50 KG HDPE Drums.

Cool & dry conditions are recommended. Extended storage or adverse conditions may lead to higher dosage requirement.

It can be stored in closed container up to six months at 25°C.

Enzyme preparation belongs to protein, which may induce sensitization and or cause allergic reactions in sensitive individuals. Prolonged contact may cause minor irritation for skin, eyes or mucous membrane of nose, so any direct contact with the human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor. MSDS is available on request.
