Continuous bioethanol production from fermentation of hydrolysed sago starch using the 'Ishizaki Process'

Continous fermentation of hydrolysed sago starch based on the 'Ishizaki process' was studied. Sago starch (20% DS) were hydrolyzed by the enzymes termamyl - 120L and dextrozyme to yield fermentable sugars at 97.6+0.6%. At a larger scale (50L), a reduction of hydrolysis yield to 62.5% was o...
