The halotolerant protease was produced and the enzyme was purified through ammonium sulphate fractionation followed by ion exchange and gel permeation chromatography. Further, the purification of the enzyme was confirmed in MALDI-TOF. A summary of the purification was shown in Table 1. The ammonium sulphate fractionation was an effective step in purification which was leading to 2.1-folds purification with specific activity of 40 U mg-1. The ion exchange chromatography with DEAE Sephadex enhanced the specific activity to 63 U mg-1 with 3.3 fold purification. During the last step of purification with gel permeation chromatography the specific activity was further enhanced to 102 U mg-1 with 5.2 folds purification
