It is hypothesized that sulphate reducing bacteria take up electron from the surface of the metal to reduce the sulphate for their anaerobic respiration thereby oxidizing the metal which leads to corrosion[28],[37], [21],[38],[39].…”

In the present study sulphate reducing bacteria (SRB) were cultured from crude water sample collected from underground water very close to rusted oil pipeline steel. Effect of Bryophyllum pinnatum leaves extract on the cultured test organism induced corrosion of oil pipeline steel was examined using media absorbance comparison, scanning electron microscope surface morphology and gravimetric techniques. The corrosion test results from the media absorbance comparison and scanning electron microscope surface morphology show inhibition activity by the test extract (Bryophyllum pinnatum leaves) on the test organism (sulphate reducing bacterial). Gravimetric analysis results confirmed, test organism induced corrosion inhibition by the test extract and the corrosion inhibition was more pronounced as the concentration of the plant extract increased. Inhibition was attributed to adsorption of the extract molecules on the pipeline steel coupons. The adsorption fitted best into Langmuir adsorption isotherm, and the trend in calculated free energy of adsorption values suggests physisorption mechanism.

“…Unlike pure-culture D. vulgaris cells that are motile, mixed-culture GHB cells in the algal culture could not be counted on a hemocytometer. CLSM was used to visualize live and dead D. vulgaris cells in the SRB biofilms on replicate coupon surfaces (Chen et al, 2015(Chen et al, , 2021 and the GHB cells in the algal-GHB mixedculture biofilms. Each biofilm covered coupon was rinsed with a pH 7.4 PBS buffer to remove the culture medium and planktonic cells before staining.…”

NiMo (nickel-molybdenum) and NiMo with embedded CeO2 nanoparticles (NPs; 100 nm) were tested as antimicrobial coatings (~15 μm thickness) on titanium (Ti) surfaces using an electrochemical process for heat exchanger applications onboard marine vessels. Preliminary static biofouling and biocorrosion (also known as microbiologically influenced corrosion) assessments were carried out in glass bottles using pure-culture Desulfovibrio vulgaris, a sulfate-reducing bacterium (SRB), in deoxygenated ATCC 1249 medium at 37°C, and using an alga (Chlorella vulgaris) mixed with general heterotrophic bacteria (GHB) in enriched artificial seawater at 28°C. It was found that the coating containing NiMo/CeO2 NPs were much more effective than NiMo in preventing SRB biofilm formation with an efficacy of 99% reduction in D. vulgaris sessile cells after 21 day incubation. The coating also exhibited a 50% lower corrosion current density compared to the uncoated Ti against SRB corrosion. Both NiMo and NiMo/CeO2 NP coatings achieved 99% reduction in sessile algal cells. Confocal laser scanning microscopy (CLSM) biofilm images indicated a large reduction of sessile GHB cells. The CLSM images also confirmed the biocidal kill effects of the two coatings. Unlike polymer coatings, the “metallic” coatings are heat conductive. Thus, the corrosion resistant antifouling coatings are suitable for heat exchanger applications.

“…Considerable attention is paid to SRB (Sungur et al, 2010;Chen et al, 2021;Tripathi et al, 2021), however, the conditions for their development are created by heterotrophic bacteria, in particular, AMB (Purish & Asaulenko, 2007;Purish et al, 2009). MIC is considered as a bioelectrochemical process that takes place in a biofilm -a highly organized, self-regulating biological system, the operation of which is aimed at optimizing their vital functions (Andreyuk et al, 2005).…”

The intensity of biofilm formation by heterotrophic bacteria possessed ammonifying ability (Bacillus simplex ChNPU F1, Streptomyces canus NUChC F2, Streptomyces gardneri ChNPU F3), ammonifying and iron-reducing ability (Fictibacillus sp. ChNPU ZVB1) previously isolated from soil ferrosphere was studied. Methods used: indirect measurement of the biomass of the bacterial biofilm using the adsorption/desorption of crystal violet, the aggregation test (to determine aggregation properties), the salt aggregation test (to determine hydrophobicity). The correlation analysis between the intensity of biofilm formation and aggregation of strains showed a significant positive correlation. The studied strains of microorganisms did not show high adhesive properties, they were moderately-adhesive (B. simplex, S. canus and S. gardneri) and weakly-adhesive (Fictibacillus sp.). It is supposed that the role these bacteria in the microbial damage of materials is determined preferably by bioelectrochemical reactions (iron-reducing bacteria) and the production of corrosive and/or antimicrobial metabolites (ammonifying and iron-reducing bacteria), but not by the biofilms formation. The prospect of further research is to analyze the antagonistic properties and biofilm formation of heterotrophic bacteria under co-cultivation conditions, in particular, with sulfate-reducing bacteria.
