“…However, when L. discophora SP-6 was combined with another corrosion-causing bacterium, Desulfosporosinus orientis, in the presence of aerobic Paenibacillus polymyxa 10401, the corrosion rate of mild steel increased significantly compared with those caused by a mixture of D. orientis and P. polymyxa 10401. In addition, it was also reported that manganese oxide deposited by L. discophora might initiate pitting corrosion of stainless steel (56). Manganese oxide may act as a cathodic reactant, increasing the corrosion of the metal on which it is deposited.…”

“…Preliminary laboratory experiments with brass indicated beginning ennoblement followed by poisoning of the MOMOs by released copper ions. Ennoblement of SS by MOMOs and subsequent initiation of corrosion by addition of chloride was also demonstrated in laboratory experiments [17,23].…”

Based on the corrosion behaviour of stainless steels in fresh water and on the electrochemical properties of higher manganese oxides, the mechanism "Microbially influenced corrosion by manganese oxidizing microorganisms" (MIC by MOMOs) is presented as the consequence of biomineralized manganese oxides in contact with the metal. Localized corrosion may develop at elevated but normally undercritical chloride concentration in the water. The mechanism was found useful in the analysis of certain cases of unexpected failure of stainless steel in fresh water.Ausgehend vom Korrosionsverhalten nichtrostender Stähle in Süßwasser und den elektrochemischen Eigenschaften höherer Manganoxide wird der Mechanismus "Mikrobiell beeinflusste Korrosion durch manganoxidierende Mikroorganismen" als die Folge des Kontaktes von biomineralisiertem Braunstein mit dem metallischen Werkstoff beschrieben. Unter diesen Bedingungen kann Lokalkorrosion bei Chloridkonzentrationen im Wasser entstehen, die normalerweise als unkritisch angesehen werden. Der Mechanismus hat sich bei der Schadensanalyse bestimmter, unerwarteter Korrosionsfälle bewährt.

“…However, these reactions can also occur at circumneutral pH (Emerson 2000 ). Additionally, the penetration of chloride and the deposition of Mn-oxides is known to cause pitting corrosion on steel (Dickinson et al 1997 , Olesen et al 2001 , Hagelia 2011 ). The acidic water causes deep disintegration and enhances the porosity of the cement paste matrix due to dissolution of portlandite and calcium silicate hydrate, leading to formation of carbonates, thaumasite sulfate attack and magnesium attack (Hagelia 2011 , Karačić et al 2018 ).…”

The Oslofjord subsea road tunnel is a unique environment in which the typically anoxic marine deep subsurface is exposed to oxygen. Concrete biodeterioration and steel corrosion in the tunnel have been linked to the growth of iron- and manganese-oxidizing biofilms in areas of saline water seepage. Surprisingly, previous 16S rRNA gene surveys of biofilm samples revealed microbial communities dominated by sequences affiliated with nitrogen-cycling microorganisms. This study aimed to identify microbial genomes with metabolic potential for novel nitrogen- and metal-cycling reactions, representing biofilm microorganisms that could link these cycles and play a role in concrete biodeterioration. We reconstructed 33 abundant, novel metagenome-assembled genomes (MAGs) affiliated with the phylum Planctomycetota and candidate phylum KSB1. We identified novel and unusual genes and gene clusters in these MAGs related to anaerobic ammonium oxidation, nitrite oxidation, and other nitrogen-cycling reactions. Additionally, 26 of 33 MAGs also had the potential for iron, manganese and arsenite cycling, suggesting that bacteria represented by these genomes might couple these reactions. Our results expand the diversity of microorganisms putatively involved in nitrogen and metal cycling, and contribute to our understanding of potential biofilm impacts on built infrastructure.
