Corrosion of iron (and other metals)-based infrastructure (for example, pipes) is an enormously costly problem faced by many industries including power generation, oil production, transportation, beverage production and water storage and distribution. Estimates of the cost are on the order of ~3% of Canada's annual gross domestic product, GDP. Corrosion prevention is not trivial, and can be highly difficult to achieve. It is now known that microorganisms (bacteria and fungi) can in many cases cause and/or worsen metal corrosion - a phenomenon known as microbiologically influenced corrosion (MIC), which complicates corrosion treatment and prevention. Biotechnology companies such as OSP Microcheck Inc produce products to help diagnose for MIC. Once diagnosed correctly, MIC type corrosion can be treated or further prevented more effectively than if left undiagnosed. Currently used MIC diagnostic methods recognise the presence of microbes, but are incapable of identifying exactly which microbes are present. As not all microbes will actually cause corrosion, it would be of great benefit to identify the microbes present, potentially even preventing un-needed and costly treatments when microbes are present, but the actual risk of MIC type corrosion is minimal. This academic-industry interaction will explore the possibility of innovating one of OSP Microcheck's current MIC diagnostic methods such that it is capable of both finding and identifying the microbes causing MIC type corrosion. This work will fill a knowledge gap in the understanding of the biochemistry behind MIC diagnostic techniques, information key to further technology developments towards a product that would both enhance MIC diagnoses and render them more cost-effective.

基于铁（和其他金属）的基础设施（例如，管道）的腐蚀是包括发电、石油生产、运输、饮料生产以及水储存和分配的许多行业所面临的成本极高的问题。 估计成本约为加拿大年度国内生产总值（GDP）的3%。 防腐蚀不是小事，并且可能非常难以实现。 现在已知微生物（细菌和真菌）在许多情况下可引起和/或恶化金属腐蚀-一种称为微生物影响腐蚀（MIC）的现象，其使腐蚀处理和预防复杂化。 生物技术公司，如OSP Microcheck Inc.生产的产品，以帮助诊断MIC。 一旦诊断正确，MIC型腐蚀可以得到治疗或进一步预防，比未经诊断更有效。 目前使用的MIC诊断方法可以识别微生物的存在，但无法准确识别存在哪些微生物。 由于并非所有微生物都会实际导致腐蚀，因此识别存在的微生物将是非常有益的，当存在微生物时，甚至可能防止不需要和昂贵的处理，但MIC类型腐蚀的实际风险是最小的。 这种学术界与工业界的互动将探索创新OSP Microcheck当前MIC诊断方法之一的可能性，以便能够发现和识别导致MIC类型腐蚀的微生物。 这项工作将填补在了解MIC诊断技术背后的生物化学方面的知识空白，这是进一步开发产品的关键信息，该产品将增强MIC诊断并使其更具成本效益。
