Effects Of Pretreatment And Enzymatic Hydrolysis On Oil Palm Frond For Use As Yeast Cultivation Medium
The advantage of acid hydrolysis is time consumed is much lower (10 minutes to 6 hours), as compared to enzymatic hydrolysis time is counted in days (Goldstein, 1983 and Wenzl, 1970). However, acid hydrolysis is hampered by non-selectivity and by-products formation from sugar decomposition (Fan et a...

The advantage of acid hydrolysis is time consumed is much lower (10 minutes to 6 hours), as compared to enzymatic hydrolysis time is counted in days (Goldstein, 1983 and Wenzl, 1970).
