An apparatus and methods to produce synergistic mixtures (or combinations) of haloamines to control growth of microorganisms in aqueous systems are disclosed. The apparatus and methods to produce synergistic mixtures entails producing a batch quantity of a haloamine and converting part of the haloamine to a second haloamine species to form the synergistic mixture.

Method and apparatus for producing synergistic biocide

Methods of inhibiting the growth of organisms in aqueous systems such as papermaking systems, cooling systems and process waters of various types, comprises adding to the aqueous system a hop acid. Compositions comprising hop acids and papermaking suspensions or slurries, and/or additives, such as paper making additives, are also provided.

Methods of using hop acids to control organisms

A process using polymerize chain reaction (PCR) technology is described for the detection of spore forming bacteria in paper products and paper manufacturing streams and additives. Disclosed and claimed are novel nucleotide primers which specifically amplify sporulation genes common to spore forming bacteria. These primers produce gene fragments diagnostic for the presence of spore forming bacteria.
