“…Among them, sulfate-reducing bacteria have been extensively known as the main culprits of microbial corrosion . It is estimated that more than 75% of the corrosion in oil fields and over 50% of all the microbial corrosion are caused by SRB . As a group of strict anaerobes, SRB can obtain their energy by oxidizing some organic compounds or molecular hydrogen (H 2 ) while reducing sulfate (SO 4 2– ) to hydrogen sulfide (H 2 S) .…”

With the objective of developing anticorrosive conductive polymeric coatings to combat microbially induced corrosion (MIC), a facile and green synthesis approach based on a thermally induced reaction was described. Thermal curing of polyaniline (PANI) was carried out from the silanized mild steel (MS) surface containing reactive epoxy groups, followed by thermally induced N-alkylation of PANI by hydrophobic 4-vinylbenzyl chloride (VBzCl) to produce biocidal functionality. The so-synthesized MS coupons with hydrophobic poly(vinylbenzyl chloride) (PVBC)−quaternized PANI bilayer coatings were investigated for their anticorrosive and antibacterial properties toward biocorrosion induced by sulfate-reducing bacteria (SRB). Antibacterial assay results revealed an evident decrease in the bacterial attachment and the formation of biofilm. The QPANI− PVBC bilayer coatings showed a high corrosion resistance (inhibition efficiency >97%) and stability to resist SRB-induced corrosion. Thus, the QPANI−PVBC bilayer coated MS substrates can be used as effective polymeric coatings to protect the steelbased equipment in corrosive marine environments.

“…Sebahagian formulasi terhadap biosid komersial ini didapati berupaya mengawal pembentukan biofilem D. vulgaris. Selain larutan biosid, penggunaan kombinasi sterina dan N-vinil-2-pirolidon dalam logam nano-komposit turut didapati memberikan kecekapan perencatan yang tinggi kepada SRB apabila digunakan sebagai saduran kepada keluli karbon (Fathy et al 2013). Namun sehingga kini penggunaan bahan biosid bagi mengawal bakteria SRB dan penggunaan bahan perencat kakisan masih melibatkan penggunaan bahan kimia yang berlainan.…”

Ancaman biokakisan akibat aktiviti bakteria penurun sulfat (SRB) PENGENALANProses pemindahan minyak mentah kerap dilakukan melalui sistem saluran paip keluli yang terdedah kepada pelbagai persekitaran, termasuk laluan di bawah tanah dan air laut. Keadaan ini telah mengundang pelbagai masalah kakisan pada kedua-dua permukaan luaran dan dalaman paip (Al-Jaroudi et al. 2011). Untuk itu, langkah pengurusan dan pengawalan kakisan dengan menggunakan kaedah seperti saduran cat, perlindungan katodik dan perencat kakisan telah digunakan. Namun kehadiran perbagai mikrobial yang menyebabkan kakisan dalam minyak mentah terutamanya SRB telah meningkatkan lagi tahap kemusnahan bahagian dalaman paip keluli (Abdullah et al. 2014;Stipaničev et al. 2013). Keadaan ini disebabkan aktiviti semula jadi SRB yang berupaya menghasilkan ion sulfida daripada tindak balas penurunan sulfat dan lainlain ikatan sulfur seperti sulfit dan tiosulfat. Tindak balas ion-ion sulfida dengan ion hidrogen terlarut menyebabkan pembentukan sebatian berasid H 2 S yang berbahaya dan toksik. Kehadiran H 2 S bukan sahaja meningkatkan kadar kakisan keluli, malah turut menurunkan kualiti minyak mentah melalui proses pemasaman serta pemendakan

“…Sulfate–reducing prokaryotes (SRP) are typical corrosive microorganisms. Fathy et al [ 6 ] believe that more than 75% of the corrosion of oil–producing wells and more than 50% of the corrosion of buried pipelines are caused by the activities of such microorganisms. In the mudflat environment microorganisms particularly tend to grow in the mudflat environment [ 7 ], which may result in localized corrosion accelerating the failure of metals [ 8 ].…”

To study the abnormal failure of magnesium anodes for buried pipelines in marine engineering in the unique environment of mudflats, a strain of a sulfate–reducing prokaryote (SRP) was isolated from pipe–laying soil, and identified as Desulfovibrio sp. HQM3. Weight–loss test, electrochemical measurements, SEM, EDS, XRD, and CLSM techniques were used to study the effect of corrosion on the AZ31B magnesium alloy. Under the influence of SRP, the magnesium alloy corroded severely at rates up to 1.31 mm/year in the mudflat environment. SRP accelerated corrosion by 0.3mm/year. Pitting occurred on the samples in both abiotic and biotic systems. The pitting depth reached 163.47 μm in the biotic system after 14 days. The main composition of a petal–like corrosion product was Mg(OH)2. The results show that a mudflat environment can lead to an accelerated corrosion of magnesium alloys.
