Abstract
Disclosed are compositions and methods for inhibiting and controlling the growth of the capsulated, facultative bacterium, Klebsiella pneumoniae. The compositions comprise 2-(2-bromo-2-nitroethenyl) furan and n-tributyltetradecyl phosphonium chloride. The method comprises adding from 1 part to about 200 parts composition to the aqueous system for which treatment is desired.
Claims7
A bacterial inhibiting composition comprising a synergistic mixture of (A) n-tributyltetradecyl phosphonium chloride and (B) 2-(2-bromo-2-nitroethenyl) furan wherein the weight ratio of (A):(B) (100% actives basis) is from about 25:1 to about 1:2.
A method for controlling the growth of Klebsiella pneumoniae bacteria in an aqueous system which comprises adding to said system from about from about 1 to 200 parts per weight of a composition per one million parts per weight of said aqueous system, said composition comprising a synergistic mixture of (A) n-tributyltetradecyl phosphonium chloride and (B) 2-(2-bromo-2-nitroethenyl) furan, the weight ratio of (A):(B) (100% actives basis) being from about 25:1 to about 1:2.
