[Multiple forms of acid phosphatase of the mould Aspergillus awamori str. 22]. / Mnozhestvennost' form kisloi fosfatazy plesnevogo griba Aspergillus awamori shtamm 22

By isoelectric focusing and DEAE-cellulose and Sephadex G-150 chromatography it has been shown that extracellular acid phosphatase produced by Aspergillus awamori str. 22 exists as a mixture of oligomers of molecular weights ranging from 30,000 to 140,000. With an increase of aggregation of molecules of acid phosphatase the isoelectric point increases from 4.6 to 5.4.
