Abstract: A method is provided for controlling deposit-forming contaminants that comprise pitch or other fiber components which can interfere with the processing of the fibers, reduce paper quality, or both in papermaking systems. The method includes contacting fibers with a lipase and at least one peroxide source-free oxidant, and optionally nonionic surfactant, to liberate the organic contaminants from the fibers. Paper products of the method are also provided.

Abstract: A method for increasing the effectiveness of the microbicide propiconazole , (see above formula) (RS)-1-2-[(2,4-dichlorophenyl)-2-propyl-1,3-dioxalan- 2ylmethyl]-1H-1,2,4-triazole, is described. In the method, propiconazole and a potentiator, an N-alkyl heterocyclic compound, its salt, or a mixture thereof, are applied to a substrate or aqueous system subject to the growth of microorganisms. The N-alkyl heterocyclic compound, its salt, or a mixture thereof is applied in an amoun t effective to increase the microbicidal activity of the microbicide. The N-alkyl heterocyclic compound has formula (I). The variable "n" ranges from 5 to 17, and the heterocyclic ring defined by (II) is a substituted or unsubstituted ring having four to eight members. Microbicidal compositions are described where propiconazole and an N-alkyl heterocyclic compound, its salt, or a mixture thereof are present in a combined amount effective to control the growth of at least one microorganism. Methods for controlling th e growth of microorganisms on various substrates and in various aqueous systems are also described. The combination of propiconazole and N-alkyl heterocyclic compound, its salt, or a mixture thereof is particularly useful as microbicidal in the leather industry, the lumber industry, the papermaking industry, the textile industry, the agricultural industry, and the coating industry, as we ll as in industrial process waters.

Abstract: Described is a method to increase the effectiveness of a microbicide comprising the steps of applying to the substrate or aqueous system subject to the growth of microorganisms a combination of propiconazole and a potentiator, where the potentiator is present in an amount effective to increase the microbicidal activity of the propiconazole and is at least one N-alkyl heterocyclic compound of the formula shown, where: n is 5 to 17; the heterocyclic ring depicted is a substituted or unsubstituted ring having four to eight members. Also described is a microbicidal composition comprising the components described above.

Abstract: An emulsified composition containing 1,4-bis(bromoacetoxy)-2-butene (BBAB) i s disclosed which has the ability to disperse and/or dissolve uniformly in aqueous systems thereby effectively controlling the growth of microorganisms. The composition contains BBAB and a nonionic emulsifier. A method for inhibiting the growth of microorganisms with this composition in an amount effective to control the growth of microorganisms is also disclosed.
