| 总结: | Oil palm frond (OPF) is one of the most abundant waste generated from an oil
palm plantation. OPF can be utilized as a feedstock for bioethanol and can
simultaneously address its disposal issue in the plantation. In this project, OPF was
divided into two types of feedstock; biomass and juice by mechanical pressing. Firstly,
the dried biomass was biologically treated using white-rot fungi; Phanerochaete
chrysosporium CK01 for biodelignification. Two parameters were tested; effect of
inoculum size and fermentation duration. The best parameters were inoculum size of
1.0x106 spore/mL and 3 weeks of fermentation duration which gave 27.87% of
delignification. In the second stage, the treated biomass was subjected to enzymatic
hydrolysis by either individual or in combination to produce a sugar hydrolysate. Two
parameters tested were enzyme loading (in individual enzymatic hydrolysis) or
enzyme ratio (in combined enzymatic hydrolysis; Cellulase A “Amano” 3 and
Hemicellulase “Amano” 90) and hydrolysis time. The result shows that the combined
(cellulase and hemicellulase) enzymatic hydrolysis produces higher amount of simple
sugar (5.15g/L) using a combination of enzyme ratio of 1:4 (cellulase:hemicellulase)
with a hydrolysis time of 120 minutes compared to individual enzymatic hydrolysis
(3.26g/L). Prior to beginning of the third stage, the amount of simple sugar in the
hydrolysate (OPFH) and juice (OPFJ) were compared using high performance liquid
chromatography (HPLC) analysis. |
