This research work has studied the role of two bacteria
namley;
Bacillus subtilis
strain S1X and
Pseudomonas
aeruginosa
strain ZK in the corrosion behavior of SS304 in
minimal salt medium with 1.5% NaCl as a corrosive agent.
Electrochemical techniques including Tafel polarization
and electrochemical impedance spectroscopy and surface
analytical techniques including atomic force microscopy,
scanning electron microscopy-energy dispersive spectrum
analysis and Fourier transform infrared spectroscopy showed
that both bacteria developed a protective layer in the form
of biofilm on the surface of SS304 and thus inhibited the
corroiosn of underlying surface of alloy. The decrease in
pH values for bacterial inoculated systems with increasing
incubation time showed the production of some acidic
metabolites by bacterial isolates.
