Sharing riboflavin as an electron shuttle enhances the corrosivity of a mixed consortium of Shewanella oneidensis and Bacillus licheniformis against 316L stainless steel

In nature, microbiologically influenced corrosion (MIC) is often caused by multi-species biofilms rather than single-species biofilms. In this work, the MIC of 316L stainless steel (SS) was investigated in the presence of individual and mixed consortium biofilms of Shewanella oneidensis and Bacillus licheniformis through electrochemical and surface characterizations. Results revealed that MIC of 316L SS was significantly accelerated by the...
