ISOLATION AND IDENTIFICTION OF THE PRODUCER AMYLASE ENZYME Aspergillus niger FROM SOME AL_RAMADI SOILS AND THE USE OF PLANT WASTES TO PRODUCE IT

Abstract

This research was conducted to study the production of amylase by the fungus Aspergillus niger which is isolated from some Ramadi soils :Also to know its adequacy in the enzyme production PH,Temperature ,Carbon source , Carbon concentration ,Nitrogen and incubation period .The highest production value was 8.0 cm at PH 5.0 , 30C with the use of (Ceratophyllum demersum ) as the only carbon source at the concentration 1.5% and for the incubation period 8 days.
