Production of Amylase from the fungus Aspergillus niger FA6 Isolated from Iraqi Soil.

Abstract

Filamentous fungi have been widely used to produce hydrolytic
enzymes for many applications. Fungal enzymes amylase were
produced using eight Aspergillus niger isolates from eight soil sample in
Iraq, were screened for amylase production. A. niger FA6 (isolated from
AL-Nasiriya soil) gave maximum amylase yield, The effect of varying
 
pH, temperature, incubation period, carbon sources and_ nitrogen
sources of the medium for the productivity of amylase from
A.nigerFA6 was _ investigated. The maximum activity of amylase was
recorded after 7 days of submerged fermentation at pH 5 and temperature
30°C. from different nitrogen and carbon sources used peptone and
sucrose respectively gave maximum amylase yield.
