The effect of magneticfield on biomineralization and corrosion behavior of carbon steel induced by iron-oxidizing bacteria

Effect of Dissolved Oxygen Concentration on the Microbiologically Influenced Corrosion of Q235 Carbon Steel by Halophilic Archaeon Natronorubrum tibetense

“…MIC has become one of the main threats in the field of oil and gas industry, water treatment industry, and marine engineering, which brings huge economic losses and potential safety hazards (Li et al., 2017). For a long time, numerous research works have been focused on sulfate reducing bacteria (SRB), iron oxidizing bacteria (IOB), sulfur oxidizing bacteria (SOB), and other bacteria (Enning and Garrelfs, 2014; Huber et al., 2016; Liang et al., 2016; Liu et al., 2016; Xu et al., 2016, 2018; Jia et al., 2017; Karn et al., 2017; Dou et al., 2018; Liu and Cheng, 2018). For the ubiquitous microorganisms in the natural environment, such as SRB, their MIC mechanisms have been studied in-depth, and comprehensive corrosion mechanisms have been well established (Venzlaff et al., 2013; Rajala et al., 2015; Li et al., 2018; Jia et al., 2019).…”

Effect of Magnetic Field on the Inhibition Performance of Corrosion Inhibitors with Different Dipole Moment Gradients

“…Furthermore, the corrosion potential and Tafel slopes in the anode and cathode show minor differences with the application of the magnetic field, indicating that the kinetics in corrosion processes are basically unaffected. In early reports about the influence of the magnetic field [20,[22][23][24][25], the magnetohydrodynamisc (MHD) was regarded as the main factor, whereas the study of molecule structure was often ignored. For the corrosion inhibitors, the change of molecular structure has a considerable effect on the adsorption performance.…”

“…On the one hand, magnetohydrodynamic (MHD) force including paramagnetic gradient force (F ▽C ), gradient magnetic force (F ▽B ), and Lorentz force (F L ), can induce migration of charged particles on the mass transfer and electrode kinetic processes [22]. On the other hand, magnetic fields can also change the metal material properties and enhance the growth of ferromagnetic oxide, thereby affecting the formation kinetics and types of corrosion products [23].…”

A mechanistic analysis of the influence of iron‐oxidizing bacteria on antimony (V) removal from water by microscale zero‐valent iron

“…They attach to the surface of iron‐rich materials and generate biological iron oxide minerals . In an aerobic environment, IOB can oxidize ferrous ions and deposit iron hydroxides extracellularly . Sphaerotilus natans , which belongs to the IOB consortia, exists naturally in ecological communities found in heavily polluted freshwater and activated sludge systems in the form of superficial mucilage layers .…”

“…26,27 In an aerobic environment, IOB can oxidize ferrous ions and deposit iron hydroxides extracellularly. 28 Sphaerotilus natans, which belongs to the IOB consortia, exists naturally in ecological communities found in heavily polluted freshwater and activated sludge systems in the form of superficial mucilage layers. 29,30 Starosvetsky et al 31 isolated IOB from rust deposits on a clogged carbon steel heat exchanger in Israel, and the primary strain also was identified as a Sphaerotilus sp.…”
