Production and optimization of phytase by Aspergillus niger
نویسندگان
چکیده
The present article implies an extracellular phytase production by Aspergillus niger under submerged and solid fermentation. Physical and Chemical conditions tested for optimal production of phytase using the single variable mode optimization technique. A considerable higher phytase production was obtained using rice bran as solid substrate (17.8 U/ml & 28.6 U/ml) at pH 5, on 4 day of incubation at 30C. It has been inferred from the results that glucose as best carbon source for phytase production with 29.5 U/ml (SMF) and 42.4U/ml (SSF) activity and ammonium nitrate as good nitrogen source enhanced production of phytase from Aspergillus niger upto 31.8 U/ml in SMF and 45.2 U/ml in SSF.

Phytases have been one of the focal enzymes for animal nutrition during the past two decades. In this work, the use of wheat bran as substrate for phytase production in Solid State Fermentation (SSF) was studied. In order to find the best fermentation conditions for phytase production using a laboratory strain indentified as Aspergillus niger, three different pretreatments (1: wheat bran withou...

A. niger XP isolated from Vietnam produces very low amount of acidic phytase with optimal pH at 2.5 and 5.5. The phytase production of this strain was successfully improved through gene cloning and expression. A 1.4 kb DNA fragment containing the coding region of the phyA gene was amplified by PCR and inserted into the expression vector pPICZαA with a signal peptide αfactor, under the control o...
