Fresh water contamination of paper mill systems may lead to outbreaks of deposits of filamentous bacteria often collectively called “pink slime.” These deposits can be difficult to treat with modern microbiological control programs, especially in mills where corrosion is a concern. We have adopted a methodology that uses DNA fingerprinting to identify problematic fresh water organisms. Once the microorganism is isolated and identified, we can then use our available biocidal actives to identify the most appropriate formulations so that the deposit can be effectively treated. Even though problem organisms can manifest in similar ways, specific problem organisms can vary widely in the optimum product and MIC required to control them. Thus, by utilizing the state of the art technology to identify problem organisms, we not only provide our customers with some of the most advanced control chemicals, but the resulting information is also entered into a database where it can be retrieved to help identify and treat problems found in other mills.
