Manufacturing engineers face a variety of challenges in processes that contain water and nutrients. A variety of microbes can grow and cause problems, yet diagnosing the problem can be difficult. The role of a consulting industrial microbiologist is to work with plant engineers to help them understand microbial behavior, how to counteract the problem, and set in place methods to that warn of increased growth that could cause new problems.

Indicators of spoilage or biofilm (slime) formation can be subtle. Relying solely on “plating” techniques and counting the bacteria and fungi can be misleading.

Problem solving as an industrial microbiologist requires knowledge of the process, water entry points, additives and dwell times. This allows proper testing to be conducted on points that define and pinpoint the problem.

Optimal industrial biofilm control (slime control) includes proper process water treatment, which can more stringent than needed for potable water. All incoming process chemicals tested for microbial quality. Appropriate testing will determine where and when to add inhibitory chemicals such as biocides and fungicides.

International Microbial Associates works to train the local staff to recognize and solve problems themselves.
