Comparative study on the suitability of corn cob and empty fruit bunch in the fermentative production of xylitol by using candida guilliermondii /Chong Meng Yeong

Comparative study on the suitability of corn cob and empty fruit bunch in the fermentative production of xylitol by using candida guilliermondii_Chong Meng Yeong_K4_2011_
Kertas ini mengkaji kesesuaian tandan buah kosong kelapa sawit dan tongkol jagung dalam penghasilan xylitol dalam proses penapaian dengan menggunakan Candida guilliermondii. Keputusan hidrolisis menunjukkan bahawa hidrolisat tongkol jagung mengandungi kepekatan glukosa dan xilosa yang lebih tinggi pada suhu reaksi setinggi 100oC dengan menggunakan 2% HCl. Kepekatan Glukosa dan xilosa yang tertinggi diperoleh dari hidrolisat tongkol jagung adalah 5.89 g/l dan 20.51 g/l masing-masing. Kepekatan glukosa dan xilosa yang tertinggi diperoleh dari hidrolisat tandan buah kosong kelapa sawit adalah 1.98 g/l dan 13.75 g/l masing-masing. Dalam kajian terakhir terhadap prestasi penapaian tandan buah kosong kelapa sawit dan tongkol jagung, tandan buah kosong kelapa sawit mempunyai kepekatan sel tertinggi pada nilai 19.3 g/l sedangkan tongkol jagung mempunyai kepekatan sel tertinggi pada nilai 18.5 g/l selepas proses penapaian sepanjang 96 jam pada suhu 25oC. ___________________________________________________________________________________ This paper studies on the suitability of empty fruit bunch and corn cob in the fermentative production of xylitol by using Candida guilliermondii. The hydrolysis results show that corn cob hydrolyzates contain higher concentrations of glucose and xylose upon hydrolysis at 100oC by 2% HCl. The highest glucose and xylose concentration obtained in the corn cob hydrolyzates were 5.89 g/l and 20.51 g/l respectively. The highest glucose and xylose concentration obtained in the empty fruit bunch hydrolyzates were 1.98 g/l and 13.75 g/l. In the latter study on the fermentation performance of empty fruit bunch and corn cob, empty fruit bunch had the highest final cell concentration of 19.3 g/l whereas corn cob had the highest final cell concentration of 18.5 g/l after 96 hours of fermentation at 25oC.
