Protected antimicrobial compounds for high temperature applications

Provided are protected antimicrobial compounds which are useful for controlling microorganisms in aqueous or water-containing systems, such as oil or gas field fluids, at elevated temperature. The antimicrobial compounds are of the formula I: wherein R, R, R, X and Y are as defined herein.

Wallboard and facing paper that provides increased mold resistance at lower biocide loadings. The biocide is: (a) an n-alkyl isothiazolinone such as octylisothiazolinone (OIT), a monohalo and dihalo substituted n-alkylisothiazolinone such as chloromethylisothiazolinone (CMIT) or dichlorooctylisothiazolinone (DCOIT), 3-iodo-2-propynyl-butylcarbamate (IPBC), chlorothalonil, methylene-bis-thiocyanate, or mixtures of two or more thereof; or (b) carbendazim and a second biocide selected from 3-iodo-2-propynyl-butylcarbamate (IPBC), diiodomethyltolylsulfone (DIMTS), sodium pyrithione, octylisothiazolinone (OIT), dichlorooctylisothiazolinone (DCOIT), and chlorothalonil.

Mold-resistant wallboard

A composition for anti-microbial effect in a water system such as a pulp and paper processing line with an aqueous slurry. The composition comprises a free chlorine-generating biocide comprising a chlorine source, urea, and an alkali in a concentration sufficient to provide a pH greater than 10, and typically at least pH 11.

Suppressing microbial growth in pulp and paper

An apparatus and method for monitoring microbiological activity in a process stream by measuring dissolved oxygen is disclosed. Bulk microbiological activity and surface associated biological activity are measured using this apparatus and method.

Method of monitoring microbiological activity in process streams

A method for locating hidden microorganism contaminated surfaces in industrial water systems is described and claimed. The method works by applying a solution or dispersion of a fluorogenic reagent in water to the hidden water contact surfaces of said industrial water system and allowing said fluorogenic reagent to react with any hidden microorganisms present, wherein said fluorogenic reagent is selected from the group of fluorogenic reagents that are known to react with microorganisms such that a fluorescent signal of said fluorogenic reagent is detectable in such a way as to make the detection of the fluorescent signal indicate that there are hidden microorganisms present on the water contact surfaces of the equipment and piping.
