Isolation and some properties of extracellular amylases from Fusarium martii var. minus f.2

α-amylase and glucoamylase were isolated from the liquid culture medium of Fusarium martii. At 10-3 M concentrations PCMB inhibited the activity of both enzymes, which indicated that they require SH groups for enzymatic activity, α-amylase was also inhibited by DFP at 10-3 M. One may thus assume that serine is present in the active center of the examined amylase
