Factors responsible for production of amylases from Aspergillus fumigatus Fresenius

Abstract

Aspergillus fumigatus Fresenius showed maximum amylase production at 27°C with an initial culture pH of the medium 6.0 after 72 h. of incubation. One per cent soluble starch and 0.15% ammonium nitrate in the medium supported the highest amylase activity. During enzyme-substrate reaction maximum enzyme activity was observed at 50°C and pH 4.0 with 2% starch. DOI: http://dx.doi.org/10.3329/cujbs.v3i1.13402 The Chittagong Univ. J. B.
