A modified method for obtaining purified L-asparaginase fromE. coli 671 is proposed. The purification includes extraction with water from an acetone powder, acid-thermal treatment, fractionation with acetone and with polyethyleneglycol, and volume chromatography on DEAE-cellulose.

The specific activity of the L-asparaginase was 200 MU/mg of protein, and the yield of enzyme 19.6%. Its purity was shown by electrophoresis in polyacrylamide gel.
