Article Synopsis
- - Microbial corrosion refers to the damage caused to materials by microorganisms, particularly in industries like oil and gas, leading to significant losses in facilities such as sewage systems and food-processing equipment.
- - Sulfate-reducing bacteria (SRB) is identified as the most harmful type of bacteria involved in this process, contributing to mechanisms like pitting corrosion and cathodic depolarization in pipelines.
- - The review highlights potential strategies for controlling microbial corrosion in pipelines, emphasizing the exploration of new, eco-friendly protection methods.

Article Synopsis
- This study investigated how effective certain antipyrine compounds are at preventing corrosion in hydrochloric acid (HCl) using advanced modeling techniques.
- Researchers used density functional theory (DFT) and machine learning methods like K-nearest neighbor (KNN) and artificial neural networks (ANN) to create predictive models, with the ANN model outperforming KNN significantly.
- The efficiencies of these antipyrine compounds in inhibiting corrosion varied widely, with the best-performing compound (A1) achieving nearly 99.79% effectiveness and demonstrating strong adsorption characteristics.
Article Synopsis
- - The study investigates the use of organic silicon quaternary ammonium salt (OSA) as an eco-friendly method to inhibit sulphate-reducing bacteria (SRB) on 20SiMn steel in simulated concrete pore solutions (SCP).
- - Four experimental conditions were tested: no SRB, no SRB with OSA, presence of SRB, and presence of SRB with OSA, over a 28-day period, identifying the bacteria's role in damaging the steel's protective layer due to their metabolic activity at a high pH.
- - Findings demonstrated that OSA effectively reduced the growth of SRB and subsequent corrosion of the steel, supported by various analytical techniques, including microscopy and electrochemical methods
