Abstract
Bactericidal composition and method for inhibiting and controlling the growth of the capsulated, facultative bacterium, Klebsiella pneumoniae, are disclosed. The composition comprises an amount, effective for the intended purpose, of 2-bromo-2-nitropropane-1,3-diol and bis (tri n-butyl tin) oxide. The method comprises administering between about 0.1 to about 200 parts of this combined treatment (based on one million parts of the desired aqueous system) to the particular water containing system for which treatment is desired.
Claims7
A bacterial inhibiting composition comprising a synergistic aqueous mixture of 2-bromo-2-nitropropane-1,3-diol (BNPD) and bis(tri n-butyl tin)oxide (BTO), the weight ratio of said BNPD to BTO being about 16:1 to 1:32.
The method for controlling the growth of Klebsiella pneumoniae bacteria in an aqueous system which comprises adding to said system from about 0.1 to about 200 parts weight of a synergistic composition per one million parts per weight of said aqueous system, said composition comprising a mixture of 2-bromo-2-nitropropane-1,3-diol (BNPD), and bis(tri n-butyl tin)oxide (BTO), the weight ratio of said BNPD:BTO being from about 16:1 to 1:32.
