| dc.description.abstract | Xylooligosaccharides (XOS) are polymers of the sugar xylose bound by β(1→4) glycoside
bonds. XOS have potency as a prebiotic and can be produced from agricultural waste
such as cassava dregs. The purpose of this study was to examine prebiotic potential of
XOS derived from cassava dregs from hydrolysis reaction catalyzed by endo-β-1,4-Dxylanase. The prebiotic activity of XOS derived from cassava dregs was examined by
the number of Bifidobacterium, Lactobacillus, and Escherichia coli in Balb/c mice
colon, the fermentation products of Bifidobacterium and Lactobacillus including changes
in pH in the colon and short chain fatty acids (SCFAs) produced by the bacteria as
well as the concentration of Ca2+ excreted through mice faeces. This study administered
XOS derived from cassava dregs at 0.5 and 1.0 g (kg.BW) for 14, 21, and 28 days. The
negative control group was Balb/c mice without XOS derived from cassava dregs. The
results showed that feeding with XOS derived from cassava dregs at 0.5 and 1.0 g/
(kg.BW) could increase the number of
both Bifidobacterium and Lactobacillus
and decrease the number of E.scherichia
coli. The main fermentation products of
Bifidobacterium and Lactobacillus were
SCFAs such as acetic acid and butyric acid
with respective concentrations of 11.57 and
2.97 mM. The pH in the colon of treatment
groups was more acidic than that of in
the control groups. The Ca2+ absorption

was increased by 0.27% (w/v) that is
characterized by decreased concentration
of Ca2+ in Balb/c mice faeces of treatment
groups. This study has led to a conclusion
that XOS derived from cassava dregs of
xylan hydrolyzed by endo-β-1,4-D-xylanase
has prebiotic effect. | en_US |
