3.4 Corrosion of SS400 carbon steel and SUS316L stainless steel
by Prolixibacter strains.
Two nitrate-reducing strains, P. denitrificansMIC1-1T and Prolixibacter sp. SD074, and one
nitrate-non-reducing strain, Prolixibacter sp. NT017, were used
to evaluate the corroding activities on SS400 carbon steel and SUS316L
stainless steel (Table S5) under anaerobic conditions. Both
nitrate-reducing strains corroded SS400 carbon steel more intensively
than Fe0 (Table 4). However, these two strains did not
corrode SUS316L stainless steel, indicating that they could not accept
electrons through the passive film formed on the surface of stainless
steel. As expected, the Fe0-non-corrodingProlixibacter sp. NT017 corroded neither SS400 carbon steel nor
SUS316L stainless steel.
