“…8 and water content. However, water content has a joint relation with soil resistivity that can be associated with aggressive corrosion [109][110][111]. Possibly the greatest dependable technique for testing soil moisture content is to use test specimens, in case time is available, or using electrochemical procedures, if a quick assessment is required.…”

Microbial corrosion has developed a foremost problematic in the oil and gas industrial field. This problem is by reason of the continual usage of water swamping in promoting oil recovery. This water moistens the walls of oil pipelines. Microbial corrosion is also present in other industries such as nuclear power reactors and in most hydropower applications. Increased corporate infrastructure also leads to increased microbial corrosion. Sulfate Reducing Bacteria (SRB) is considered as the main kind of bacterial which cause of pipeline corrosion. Because of microbial deterioration is not understood, until recently, there is no clear mechanism to explain why and how microbial corrosion occurs because of the complexity of this area. The new theory of biocatalytic cathodic sulfate reduction is bio-electrochemistry based. In this theory, the bioenergetics can explain why microbial corrosion occurs, while the extracellular electron transference theory is capable of explain how microbial corrosion happens. The microbial corrosion can be caused by nitrate reducing bacteria, which led to an analogous biocatalytic cathodic nitrate reduction theory. The electron mediator assessment intended to validate the extracellular electron transference progression which anticipated in biocatalytic cathodic sulphate reduction. The electron mediators like riboflavin and flavin adenine dinucleotide were accomplished of hastening the microbial corrosion by indorsing electron transport flanked by an iron surface and a biofilm. In case of deficient in organic carbon, the elemental iron substituted the organic carbons as an energy source/electron donor for SRB to get their conservation energy. Under unembellished undernourishment of organic carbon, the largest pit depth was accomplished, which was consistent with the estimate of biocatalytic cathodic sulphate reduction. The developing request and crucial necessity in oil and gas industry is to find an effectual method to avoid and/or mitigate microbial corrosion at a rational cost.

“…In this study the effect of these two substances on the bacterial growth was completely different; diesel enhanced the growth, while bunsen reduced it. Many studies reported the ability of bacteria to grow in diesel containing media but not diesel [11,12]. In term of antibiotic sensitivity, the results in table 2 didn't show much difference among bunsen and diesel nor to the wild type, only slit changes have been observed.…”

Numerous bacteria expose to different materials every day. Bacterial genome mainly composed of a single double-stranded circular DNA molecule, which can easily undergo changes or mutations upon the exposure to many substances. The aim of this study was to evaluate the mutagenic effect in term of growth rate and antibiotic sensitivity of some natural and petroleum based materials on Staphylococcus aureus. Exposure to each of Bunsen and acetone lower the growth rate of bacterial cells compared to diesel and engine oil that dramatically stimulate their growth. Tobacco based products and the low concentrations of tea and coffee accelerate the growth. The high concentrations of caffeine inhibit the bacterial growth. Wild type bacteria was sensitive to most of used antibiotic and gained resistance to many of them after the exposure to the petroleum products. Similarly, tobacco and tea, which accelerate the growth of cells, make them also completely resistant to the antibiotics that inhibit the synthesis of cell walls. Based on the obtained results, it can be concluded that even natural products can induce bacterial gene mutations such as antibiotic resistance.

“…Pelletier et al [58] studied MIT/CMIT in rats, and on recommended levels for the microbial treatment in fuels, in this accidentally ingested of these ones is not expected to express a significant health risk. Other authors who cited the isothiazolinone biocide in their research were: Passman [9], Zimmer [6] and Bautista et al [52], indicating the considerable interest in this biocide for use in biodiesel and its mixtures.…”

“…The authors who included information regarding this type of biocide in their works are: Passman [9], Zimmer [6], Bautista et al [52] and Zimmer et al [18]. For example, in Bautista et al’s work [52], ten biocides were studied in samples of diesel oil in fuel storage tanks. The authors observed that the best results were related to the water-soluble biocides, notably those with an oxazolidine group.…”

Biocides Used as Additives to Biodiesels and Their Risks to the Environment and Public Health: A Review

et al. 2018

One of the advantages of using biodiesel and its blends with diesel oil is the lower levels of emissions of particulate matter, sulfur dioxide, carbon monoxide, among others, making it less harmful to the environment and to humans. However, this biofuel is susceptible to microbial contamination and biodeterioration. In this sense, studies on the use of effective low toxicity biocides are being carried out, and this work aims to present the latest information (2008–2018) available in the scientific databases, on the use of biocides in biodiesel, mainly concerning their toxicity to the environment and public health. The results showed that in relation to the control of microbial contamination, the current scenario is limited, with seven publications, in which the most studied additives were isothiazolinones, oxazolidines, thiocyanates, morpholines, oxaborinanes, thiocarbamates and phenolic antioxidants. Studies regarding direct experiments with humans have not been found, showing the need for more studies in this area, since the potential growth of biodiesel production and consumption in the world is evident. Thus, there are need for more studies on antimicrobial products for use in biodiesel, with good broad-spectrum activity (bactericidal and fungicidal), and further toxicological tests to ensure no or little impact on the environment.
