| Abstract: |
Petroleum
product pipelines in India
are found to contain a large number of various types of microorganisms either
aerobic or anaerobic and these microorganisms either directly or indirectly
enhance corrosion. Field studies have been carried out by CECRI to investigate
the corrosion problem in a cross-country pipeline transporting petroleum
product (diesel) for about 1400 km. Heterotrophic bacteria, iron bacteria,
manganese oxidizers, acid producers were enumerated and identified in the
pipeline whereas SRB could not be noticed in the pipeline. The reason for the
absence of SRB is explained in the present study. Moreover, the interaction
between heterotrophic and chemolithotrophic bacteria is explained with FTIR and
NMR analysis. Influence of inhibitor on microbial corrosion has been
investigated and the importance of selection of inhibitor has also been
explained.
