The influence of surface microbial diversity and succession on microbiologically influenced corrosion of steel in a simulated marine environment

Abstract: To explore how a succession of bacteria grown on steel coupons in a marine environment can influence their corrosion process, we designed a microcosm in laboratory to evaluate corrosion kinetics and microbial diversity over 30 days. The results described a clear influence of corrosion by a succession of different bacterial groups. During the initial period, 2-7 days, a sharp increase in the rate of corrosion was detected accompanied by the presence of Alteromonadaceae, Vibrionaceae, Oceanospirillaceae, Rhodoba… Show more

“…are known manganese oxidisers (33) and bacteria with this phenotype are associated with corrosion of iron and steel (34). They also could be common surface colonizers contributing to initial MIC biofilm development as reported for several bacterial families including Alteromonadaceae ( Microbulbifer ) (35).…”

“…Indeed, there are few studies on MIC studies in microcosm conditions. However, such studies have provided valuable information about the microbial structures involved, directly or indirectly in metal corrosion (Rajala et al 2015;Ramírez et al 2016;Li et al 2017;Moura et al 2018).…”

“…Nonetheless, establishing the direct relationship between biofilm and metal corrosion under laboratory conditions, employing a single bacterial species, may not reflect reality, since there is usually the participation of a complex microbial community. An alternative is the use of microcosm systems, where there is an effort to design a closed system in the laboratory that simulates the maximum conditions present in the environment (Angell et al 1997;Mumford et al 2016;Moura et al 2018). One methodology that has been widely employed for the study of biocorrosion under meso-and microcosm conditions, and also in situ environmental conditions, is the description of the microbial community through sequencing of the 16S ribosomal gene.…”

“…Within bacteria, sulfate‐reducing bacteria (SRB), have the largest impact on corrosion due to widespread distribution of sulfate in anoxic environments . SRBs have been implicated in the corrosion of cast iron and steel, ferritic, and other highly alloyed stainless steels, copper nickel and high nickel molybdenum alloys, and so forth …”
