Compositions comprising 2-(thiocyanomethylthio)benzo-thiazole and at least one organic acid or its salt are disclosed which are synergistically effective compared to the respective components alone in controlling the growth of microorganisms in or on a material or medium. Methods to control the growth of microorganisms and prevent spoilage caused by microorganisms with the use of the compositions of the present invention are also disclosed.

Synergistic antimicrobial compositions containing

A method for controlling the growth of at least one microorganism in an aqueous system susceptible to the growth of said microorganism and in recognized need of said control comprising the step of adding to said aqueous system an ionene polymer in an amount effective to inhibit the growth at least one microorganism selected from Campylobacter spp., Mycobacterium spp., Shigella spp., ribrio spp., Yersinia spp., Entamoeba spp., and poliovirus. The aqueous system is selected from potable water, sewage, and other nonmarine surface water. Methods for controlling the spread of the diseases cholera and polio are also disclosed.

Synergistic combinations of ionene polymers and hexahydro-1,3,5-tris(2-hydroxethyl)-s-triazine for use in controlling fungal and bacterial growth in synthetic metal working fluids.

Synergistic combinations of ionenes with

A method for inhibiting the growth of microorganisms in which an N-dodecyl heterocyclic compound in an amount effective to inhibit the growth of microorganisms is contacted with an aqueous system susceptible to such growth. N-dodecyl heterocylic compounds are also shown to be useful as microbicides in the inhibition of the formation of slime in aqueous systems or the deterioration or disfigurement of susceptible substances due to microbiological growth. Microbicidal compositions containing an N-dodecyl heterocyclic compound in a non-pharmaceutically acceptable carrier are also described.

N-dodecyl heterocyclic compounds useful as industrial microbicides and

Disclosed here are synergistic combinations of 2-(Thiocyanomethylthio)benzothiazole and hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine for use in controlling the growth of at least one microorganism, such as fungi and bacteria, in aqueous fluids, such as metalworking fluids. Methods of controlling the growth of at least one microorganism are also disclosed.
