| Abstract: | This
study presents a review on applications of phytase from thermophilic fungal
isolate, Sporotrichum
thermophile.
Under optimization, improvement in phytase production can be achieved in both
solid state (2-fold)
and
submerged (2.6-fold) fermentations. Phytase could also be produced by
alginate-immobilized S. thermophile,
and
enzyme production was sustainable over 5 repeated cycles. Purified phytase is a
homopentameric glycoprotein
(mol
mass, 456 kD) and is optimally active at pH 5.0 and 60°C with a T1/2
of 16 h at 60°C and 90 min at 80°C. It
is
insensitive to trypsin and pepsin, and unaffected by EDTA. Phytase has all
requisite properties for application
as
a feed and food additive, dephytinization of soymilk and wheat flour and soil
conditioner for plant growth
promotion. |
