ABSTRACT

 

The corrosion potential of AISI 304 stainless steel coupons influenced by sulphate-reducing bacteria (SRB) has been studied. Pure colony of SRB was isolated from the Malaysia Marine and Heavy Engineering, Pasir Gudang, Johor. Open circuit potential measurements were carried out in variable types of culturing solutions with SRB1, SRB2, combination of SRB1 & SRB2 and without SRBs inoculated. Results showed that the corrosion potential, Eoc increased in the presence of SRBs (in pure and mixed culture) compared to that of control. EDS analysis showed the strong peak of sulphur in coupon containing SRB cultures compared to the control. ESEM data showed  that the high density cell of SRBs were associated with corroding sections of surface steel comparing with non-corroding sections for coupons immersed in VMNI medium containing SRBs.

 

Keywords: open circuit potential; stainless steel; sulphate-reducing bacteria

 

 

ABSTRAK

 

Keupayaan kakisan kupon keluli kalis karat bersiri 304 yang dipengaruhi oleh bakteria penurun-sulfat (SRB) telah dikaji. Koloni tulen SRB telah dipencilkan dari Kejuruteraan Berat dan Marin Malaysia, Pasir Gudang Johor. Pengukuran keupayaan litar terbuka telah dijalankan dalam berbagai-bagai-bagai jenis larutan pengkulturan menggunakan SRB1, SRB2, kombinasi SRB1 dan SRB2 serta larutan tanpa kultur SRB. Keputusan menunjukkan keupayaan kakisan, Eoc meningkat dengan kehadiran SRB (dalam kultur tulen dan gabungan kultur) berbanding kawalan. Analisis EDS menunjukkan puncak sulfur yang tinggi dalam kupon yang mengandungi kultur SRB berbanding kawalan. Data dari mikroskop elektron imbasan sekitaran (ESEM) menunjukkan kepadatan sel SRB yang tinggi berasosiasi di bahagian permukaan keluli yang karat berbanding bahagian yang tidak berkarat bagi kupon yang direndam dalam larutan VMNI yang mengandungi SRB.

 

Kata kunci: bakteria penurun-sulfat; Keluli kalis karat; keupayaan litar terbuka
