Abstract
Various types of lignocellulosic material were screened to obtain a maximum
reducing sugar through solid substrate fermentation system by using different types
of fungal strains. Production of lignocelluloses degrading enzymes on lignocellulosic
material from each strain of fungus was varied with the types of lignocellulosic
material used. In this research, oil palm frond and Aspergillus niger USM AI1 were
chosen as potential substrate and fungus for the production of reducing sugar after
the screening process. Production of reducing sugar by A. niger USM AI1 on oil
palm frond was about 53.90 mg/ g substrate and fungal growth obtained was about
1.23 glucosamine/g substrate. The content of holocellulose in oil palm frond was
about 60.71% (w/w). Oil palm fronds were pretreated using physical and chemical
methods. Pretreatment process on the oil palm frond had caused the morphological
changes on its surface. Oil palm fronds that were autoclaved using water (OPFAuto)
were found to be the most effective pretreatment method resulting in enzyme
production of 70.20 mg/g substrate reducing sugar. Optimizations of physical and
chemical parameters were carried out in order to enhance the production of reducing
sugar for the solid substrate fermentation.
