Deciphering microbial communities involved in marine steel corrosion using high‐throughput amplicon sequencing

Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.
Aggressive forms of intertidal steel corrosion are shown to involve complex microbial consortia including sulfate‐reducing, sulfide‐oxidizing and iron‐oxidizing bacteria along with others including electroactive microbes. Statistical analysis shows the populations are derived from local bed sediment, indicating sediment anoxia as a risk factor for ...

Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the
