Enzymatic hydrolysis of sago fronds and leaves for production of sugar

Production of sugar was performed in 1 L lab scale vessel from two types of sample (sago leaves and fronds). The samples were divided into three conditions (syrup, dried solid and fresh solid). The syrup was enzymatically hydrolyzed for 26 hours (2 hours for liquefaction and 24 hours for saccharific...
