Rust is an expensive problem
Did you know that underwater microbes can be major enablers of corrosion? It is called microbially influenced corrosion (MIC) and has been recognized as a problem for more than a century. It causes damage on undersea infrastructure, like pipelines, resulting in expensive repairs.
Sulfate-reducing bacteria (SRB) are recognized as a primary cause of MIC.
Environomics FSP postdoc Xiao Deng, who is currently researching cultivation methods of SRB’s has demonstrated an environmentally friendly and cost-effective way to reduce these impacts – using electricity!
