INTRODUCTION Isolation of Aspergillus niger from garden soil for the production of amylase enzyme and effect of various parameters on enzyme‚ production is the main aim of this study. Enzymes are protein catalysts synthesized by living systems and are important in synthetic as well as degradative process. Amylases are starch degradative enzymes that catalyze the hydrolysis of internal a-1‚ 4-0-glycosidic bonds in polysaccharides such as starch in to simple sugar (glucose and maltose). It is produced
