Systems and methods as disclosed herein automatically provide real-time dosing corrections for an industrial process wherein enzyme blends are applied to natural fibers for pulp/paper production. An initial enzyme blend (e.g., enzymes and supporting formulation components, as relevant) and respective dose rates are selected to be applied based on expected fiber surface substrate characterization, expected fiber quality characterization, the physical conditions of the system being treated, respective characteristics of the initially selected enzyme blend components, etc. Upon application of the initial enzyme blend, online sensors provide real-time feedback data corresponding to measured actual values for the fiber surface substrate characterization and fiber quality characterization. A replacement enzyme blend (enzymes and supporting formulation components) and respective dose rates thereof is dynamically selected based on the feedback data. The enzyme dosing stage can be optimized responsive to product changes and/or variations in fiber sources/blend and/or physical conditions, substantially in real time.

System and method of dynamic corrective enzyme selection and formulation for pulp and paper production

Methods for controlling the growth of microorganisms in or on a product, material, or medium, such as a fermentable or fermenting medium, susceptible to attack by a microorganism, by treating with aqueous solution comprising monochloramine and at least one organic acid in a synergistically microbicidally effective combined amount to control unwanted microbial growth. Microbicidal aqueous solutions containing monochloramine and at least one organic acid in a synergistically microbicidally effective combined amount to control the growth of at least one microorganism are also described.
