A thermostable maltose-tolerant alpha-amylase from Aspergillus tamarii.

An homogeneous fraction of alpha-amylase from Aspergillus tamarii was obtained by means of a very easy purification procedure. The enzyme is a glycoprotein containing 32% saccharide and MW of 37.5 kDa.

Temperature effect in the production of multiple xylanases by Aspergillus fumigatus.

This work has evaluated the temperature effect in the production of multiple xylanases by a locally isolated strain of Aspergillus fumigatus Fresenius. Three isoenzymes, identified as xylanases I, II, and III with apparent molecular weight of 45.7 KDa, 39.
