Microbially Influenced Corrosion and its Control Measures: A Critical Review

Abstract

Corrosion of materials, induced either by chemicals, or environmental factors or microbials is always a threat to industries. If remain unattended, it will have direct influence on environmental pollution. In recent years lot of work is reported on microbially influenced corrosion which is more prevalent in biotechnology and chemical engineering process industries. However, reports for preventive measures which are taken to mitigate microbially induced corrosion are highly limited. This review is an attempt to consolidate and make a systematic, up to date report on various control techniques that could be implemented to overcome microbially influenced corrosion. The review report opens up by highlighting the causes and concerns related to microbially influenced corrosion, and explains in detail mechanistic aspects of it. It provides in-depth view on attenuating microbially influenced corrosion by using synthetic compounds, green inhibitors, surface modifications, biofilm formation, and nano-particles. The review critically discusses the corrosion inhibition mechanism with merits and limitations of each microbially influenced corrosion inhibitors.

Microbial Diversity of the Produced Waters from the Oilfields in the Republic of Tatarstan (Russian Federation): Participation in Biocorrosion

“…Previous research work confirmed that Enterobacteriaceae were involved in the biocorrosion of metallic materials under marine conditions [63]. Metal-reducing bacteria of the genus Shewanella are reported to be involved in biocorrosion [64][65][66] and were detected only in sample PW_N3. On the other hand, the facultative anaerobic bacterium Shewanella xiamenensis CQ-Y1, isolated from the wastewater of the Changqing oilfield in China, was proposed by researchers for application in the field of biodegradation and bioremediation.…”

Exploring the potential of Natural Chitosan Extracted from Cockroaches in Zinc-rich Epoxy Paints on Carbon Steel to improve the Corrosion resistance of Coating

“…The anaerobic bacteria called Sulfate-reducing bacteria (SRB) are responsible for more than half percent of microbiologically in uenced Corrosion. Carbon steel is frequently reported to be the victim of Corrosion caused by SRB [9][10][11].…”

“…9 (C2 and C3 ), the SEM images of the ZRP/CH composite coatings with 1% industrial medium Molecular weight chitosan in C2 and 1.5% in C3 sample coating are presented. While the SRB was able to produce a large amount of EPS…”
