PURPOSE:An antimicrobial agent useful for sterilizing or controlling microorganisms in service water system such as cooling water system, etc., showing improved synergistic effect with respect to antimicrobial activity, comprising a mixture of 2-bromo-2-nitro-1,3-propanediol with another compound as an active ingredient. CONSTITUTION:2-Bromo-2-nitro-1,3-propanediol shown by the formula I and 1,4- bis(bromoacetoxy)-2-butene shown by the formula II known as anitimicrobial agents are blended in a weight ratio of (1:19)-(19:1), most preferably (4:1)-(1:1), to give an active ingredient. It is effective against Pseudomonas, other bacteria, molds, etc. causing slime, pink bacteria, etc. causing pink slime of paper-making system, capable of preventing slime obstacle such as reduction in heat exchange efficiency of heat exchanger, clogging of channel, or occurrence of paper breakage and spots in paper-making system. The concentration of the two components is 0.1-200mg/l calculated as pure total amount. |
