Table 2: Total (TS) and reducing sugar (RS) of arabinan hydrolysis in batch reactor (mg/ml). Four mixing ratios of arabinan with viscozyme as mentioned in Table 1 were used in the reactor then permeates were measured after 1, 2, 3, 4 and 5 h of incubation. Total sugar and reducing sugar, equivalent to arabinose, were averaged for triplicate samples. Time 0 represents values in the feed. RS / TS were calculated by dividing average reducing sugar values by total sugar values for each time.
