RashidAhmad Safuan 52014145Oil and gas pipeline systems often fail due to Microbiologically Influenced
Corrosion (MIC). Chemical biocide is one of the common treatments to combat
MIC. However, this method is costly and further usage of chemical biocides may
lead to serious environment pollutions. In an attempt to disinfect Desulfovibrio
vulgaris, a species involved in MIC from oil and gas pipelines, ultraviolet
wave is used as a potential alternative. D. vulgaris (ATCC7757) was cultured
in broth number 1249 (Modified Barrs Medium) and the medium was adjusted
to pH 9.5 at 37°C based on the Sulfate Reducing Bacteria (SRB) optimum growth
parameters. Carbon steel coupons grade API 5L X70 were cut to approximately
10x20x5 mm and kept in anaerobic vials along with the cultured medium. The prepared
samples were incubated for 11 days, followed by exposure to ultraviolet for
1 h. Results from the study elucidated that ultraviolet (UV) is a viable option
for SRB disinfection and could effectively reduce the growth of SRB.]]>Al-Sulaiman, S., A. Al-Mithin, A. Al-Shamari, M. Islam, S.S. Prakash,20102010Barnard, J.E. and H.D.R.
