摘要

In this study, oil palm empty fruit bunch (EFB) and kenaf core fibers were converted into sugar for bioethanol production. Results of enzymatic hydrolysis showed that the untreated EFB and kenaf core fibers were hardly to be hydrolysed, in which yielded only 2.6% and 0.4% of reducing sugar (glucose), respectively. In consideration to environmentally friendliness, simple aqueous pre-treatments were carried out prior to hydrolysis aimed to increase sugar production. Based on the results obtained, it was interesting to note that by adopting merely water, acid and alkaline pre-treatments, the total glucose yields were increased to 34.9%, 34.2% and 27.9% for EFB fiber, while 19.3%, 11.7%, and 12.6% for kenaf core fiber, respectively. The results of chemical composition analysis of pre-treated fibers indicated the increase of the sugar production was highly related to the removal of hemicellulose and/or lignin in the fibers. Between the two fibers, pre-treated EFB fiber attained the highest total glucose yield in all the pre-treatments. This revealed that EFB fiber was more viable for sugar production than kenaf core fiber.
