Production of amylase by Aspergillus fumigatus utilizing α-methyl-d-glycoside, a synthetic analogue of maltose, as substrate

Abstract

A strain of Aspergillus fumigatus isolated from soil was able to produce biomass and high amylase activities in media containing α-methyl-d-glucoside (αMG), a synthetic analogue of maltose, as the only carbon source. αMG was a more effective inducer than starch and maltose at the same concentration: αMG cultures produced about 3 times more α-amylase and glucoamylase activity than starch cultures. Maximum production of α-amylase (60 U/mg) and glucoamylase (130 U/mg) was obtained in 8–10-days αMG cultures.
