Geabacter species enhances pit depth on 304L stainless steel in a medium lacking with electron donor [PDF]
, 2009 Geobacter sulfurreducens bacteria increased the open circuit potential of 304L stainless steel by around 320 mV in only a few hours after inoculation. This represents a significant increase in the corrosion risk.

Temperature, inocula and substrate: contrasting electroactive consortia, diversity and performance in microbial fuel cells [PDF]
, 2018 The factors that affect microbial community assembly and its effects on the performance of bioelectrochemical systems are poorly understood. Sixteen microbial fuel cell (MFC) reactors were set up to test the importance of inoculum, temperature and ...
