Abstract: | The lipase from Candida paralipolytica was purified, as judged by disc electrophoresis. The purification was about 132 fold, based on protein, with a recovery of 32% from the acetone precipitate of the cultivated broth.After purification, modification of the enzyme was performed by dialyzing its solution against 1 m sodium chloride in acetate buffer at room temperature and by separating the modified enzyme from an unknown substance(s) with a Sephadex G–75 column.The optimum pH for lipolysis of the purified lipase was 8.0, while that of the modified one was 7.0. Sodium taurocholate was required essentially by the purified enzyme, but not by the modified one. The purified lipase was stable below 37°C and in the pH range from 3.5 to 9.0 at 5°C. |
