Abstract The global economic burden of microbial corrosion metals is enormous. Microbial iron‐containing most extensive under anaerobic conditions. Microbes form biofilms on metal surfaces and can directly extract electrons derived from the oxidation Fe 0 to 2+ support respiration. H 2 generated abiotic also serves as an electron donor for respiratory microbes. metabolites accelerate this oxidation. Traditional strategies curbing include cathodic protection, scrapping, a diversity biocides, alloys that protective layers or release toxic ions, polymer coatings. However, these approaches are typically expensive and/or limited applicability not environmentally friendly. Biotechnology may provide more effective sustainable solutions. Biocides produced with microbes be less eukaryotes, expanding environments potential application. Microbially surfactants diminish biofilm formation by corrosive microbes, quorum‐sensing inhibitors. Amendments phages predatory bacteria have been successful in attacking laboratory studies. Poorly deposit extracellular polysaccharides minerals protect surface their metabolites. Nitrate amendments permit nitrate reducers outcompete highly sulphate‐reducing reducing corrosion. Investigation all mitigation its infancy. More study, especially relevant conditions, including diverse communities, warranted.

Biofilms are accumulations of microorganisms in an extracellular polymeric substance matrix which composed polysaccharides, proteins, lipids, and nucleic acids. Many bacteria can switch between a planktonic form biofilm form. The have relatively high cell growth reproduction rates reduced likelihood survival but adapt to occupy new habitats. state appears be natural predominant bacteria. need for the formation bacterial is that it enhances tolerance harsh environmental conditions, thereby allowing avoid being washed away by water flow or bloodstream simply attaching surface tissue, EPS protects cells, deeper layers, against antimicrobial agents, probably limiting diffusion these agents. Biofilm steps initial contact/attachment surface, followed micro-colony formation, maturation architecture biofilm, finally detachment/dispersion biofilm. Once formed, restricts mobility increases density. Secretions autoinducers into environment critical cross-signaling This cross-talk called quorum sensing (QS). Quorum cell–cell communication mechanism allows specific processes controlled, such as virulence factor expression.

Microbiologically influenced corrosion (MIC) is a crucial issue for industry and infrastructure. Biofilms are known to form on different kinds of surfaces such as metal, concrete, medical equipment. However, in some cases the effect microorganisms material can be negative consistency integrity material. Thus, overcome issues raised by MIC system, physical, chemical, biological strategies have been considered; all having their own advantages, limitations, sometimes even unwanted disadvantages. Among methods, biocide treatments antifouling coatings more common controlling MIC, though they face challenges. They lack specificity microorganisms, leading cross-resistance requiring higher concentrations. Moreover, pose environmental risks harm non-target organisms. Hence, demand eco-friendly, long-term solutions increasing regulations tighten. Recently, attentions directed application nanomaterials mitigate or control due significant antimicrobial efficiency potential lower risk compared conventional biocides coatings.
