Abstract
Arabinose is a five carbon sugar which exists in nature as a component of hemicellulose and pectin polymers,
naturally occurs in L
-
configuration
. It is used as diet controlling food additive, important intermediate for anti
-
virus drug synthesis and
as
base
material in the production of vitamin B
2
, among other
applications
.
Commercial
production of L
-
arabinose begins with the acid hydrolysis of gum arabic followed by expensive purification
steps.
Nowadays biopurification
have become an attractive approach for
purifying
high
-
value
sugars
from
lignocellulosic hydrolysates
.
Ogataea zsoltii
yeast
was investigated in terms of its ability
to perform arabinose biopurification on
semidefined medium and
on
the supernatant of acidi
c hydrolysis of corn fibre.
Arabinose biopurification was
performed in shake flasks and bench
-
top
bioreactor
under aerobic conditions.
Based on our results, this strain
can be used for arabinose biopurification on both medium
,
resulting in
near 90 % purity for arabinose
