Abstract
Alkaline phosphatase (orthophosphoric monoester phosphohydrolase, EC 3.1.3.1) of the halotolerant yeast Debaryomyces hansenii was purified by a procedure involving cell disruption, DNAase treatment, ethanol precipitation, gel filtration, chromatography on DEAE-Sephadex, and preparative polyacrylamide gel electrophoresis. The specific activity was increased 1250-fold as compared to the activity of cell free extract. The total recovery was 30%. Various modifications of the growth conditions had slight or no effect on the yield of enzyme.
