Detergents contained enzymes that claim stronger washing ability and less damages are used widely for washing out blood or minute tissues adhered to various operation apparatus. It is known that enzyme protein shows maximum activity at 40℃ and is more stable when stored at the lower temperature. However, detergents contained enzymes are stored at room temperature in the most of operation theaters, and furthermore they are transported from manufacturers to any of distribution route in nonrefrigerated condition. When we measured Protease activities at 4℃ and 40℃ during 161 days storage period, the activity at 4℃ was stable but at 40℃ decreased 38.0% in average. In comparison of Protease activities at 20℃ and 40℃, the latter showed twice higher activity. When we studied the correlation between temperatures and the washing ability of detergents contained enzymes using Adenosine triphosphate as the marker, the washing ability at 40℃ was stronger than that at 20℃.
