Abstract: A method is provided for controlling organic contaminants, such as xylans, pitch or both, that interfere with bleaching of fibers and/or cause other interference(s) in papermaking systems. The method includes contacting fibers before any bleaching thereof with a composition which contains a hemicellulolytic enzyme and an organic contaminant removal adjuvant to liberate the organic contaminants from the fibers. The treated fibers can then be bleached and further used, for example, in making paper. The present invention also relates to the treatment compositions and to paper products made with fiber materials treated with these compositions. A method of enhancing enzymatic degradation of a substrate as well as formulations and systems for achieving the same are also provided. Various substrates can be degraded or otherwise processed, including biomass, paper mill sludge, and animal hides. Enzymatic degradation can be enhanced by including one or more polymeric surfactants.

Abstract: A method and composition for killing, preventing, or inhibiting the growth of microorganisms in an aqueous system or on a substrate capable of supporting a growth of microorganisms are provided by providing a lactoperoxidase, hydrogen peroxide or a peroxide source, a halide, other than a chloride, or a thiocyanate, and, optionally, an ammonium source, under conditions in which the lactoperoxidase, peroxide from the hydrogen peroxide or peroxide source, halide or thiocyanate and ammonium from the ammonium source interact to provide an antimicrobial agent to the aqueous system or substrate.

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.
