“…These conditions, combined with the presence of biocides, can trigger morphological responses in the bacterial population that immediately adhere to a surface as a survival strategy. After the biofilm adhesion phase, the growth phase can occur in pipes with low flow rates or storage tanks, where both water and suspended solids settle to the bottom creating conditions where sessile bacteria are exposed to intermittent cycles of presence and depletion of nutrients, resulting in matured biofilms (Jenneman & de Leόn, 2022). The resistance of biofilms to biocides increases with their level of maturity, reaching minimal inhibitory concentrations up to 10 times higher than the ones used on planktonic bacteria cells (Sauer et al, 2009).…”

Microbial control in oil fields can be considered a complex subject, since microbiome diversity and physical-chemical characteristics of produced water (PW) originate a unique profile in oil fields. Standard biocides are used as chemical treatment, but the toxicity and the high volumes can cause elevated environmental impacts. Treatment effectiveness and, consequently, reduction of environmental impact may be improved through an adequate planning. The present study examines the bacterial resistance mechanisms to biocides and suggests a 5-step approach for the treatment planning: 1) determination of objectives; 2) bioaudit; 3) selection of biocide(s) in laboratory; 4) selection of representative Key Performance Indicators (KPI); and 5) monitoring of the treatment. Finally, this article demonstrates an optimization of a biocide treatment using the 5-step approach. The results show a reduction of approximately 50% in the dosage of the biocide, as well as reduction in frequency of dosage.

The loss of materials due to corrosion is inevitable and has gained significant attention at various stages in the process industries, including petroleum, food processing units, and tanneries. With significant detrimental effects occurring as a result of microbial activity, the research on microbial corrosion and methods to keep them under control has become essential. About 10% of the corrosion affliction to metals and non-metals is due to microbial activity. The Microbiologically Influenced Corrosion (MIC) is a consequence of the contact, which are synergetic between bacteria and metals. A typical marine electroactive bacterium shown to produce severe MIC is Pseudomonas aeruginosa. In the maritime environment, Pseudomonas aeruginosa is a bacteria that is extremely corrosive to stainless steel. However, little is known about how P. aeruginosa causes corrosion on stainless steel. Stainless steel is a beneficial material that has been employed in various applications due to its corrosion-resistant properties and mechanical strength. The property of stainless steel to strongly resist corrosion is owed to the presence of chromium in its composition. The chromium forms a passive film of chromium-rich oxide in aerobic conditions at low temperatures, which protects it from the surroundings. This layer can be harmed by harsh weather conditions. The microbial activity and their existence can modify the inorganic passive layers, raising their dissolution levels and detaching them from the surface of the metal. The review aims to study steel corrosion as a result of microbial activity. The explicated methodologies are more significant within the broader context of metal–microbe interactions.
