All test parameters were chosen based on actual field conditions to have more reliable and attributable results. Sulfate reducing bacteria (SRB) strain, Desulfovibrio desulfurincans, was used...

... and storage tanks are susceptible to corrosion due to bacteria and oxygen. Bacterial populations in source waters and stagnant waters as well as create bio films that attach to pipelines and storage tank walls. Sessile biofilms may contain acid producing bacteria (APB) or sulfate reducing bacteria (SRB). SRBs...

On the contrary, nitrate reduction to nitrogen has a much larger potential that was capable of driving Type I copper corrosion. sulfate reducing bacteria nitrate reducing bacteria microbiologically...

... isolates exhibit intrinsic resistance to common biocides to such an extent that they propagate in common hospital disinfectants. ⁵ The corrosion-promoting capacity of microorganisms, and sulfate reducing bacteria (SRB) in particular, has been recognized for over 50 years, a process often...

.... Type I MIC involves microbes such as sulfate reducing bacteria (SRB), nitrate/nitrite reducing bacteria (NRB) and methanogens, which are collectively called “XRB,” in which “X” stands for sulfate, nitrate, nitrite, CO₂ or another non-oxygen oxidant and “B” for bugs that include prokaryotes...

Its primary aim is to improve understanding of the influence of microbiological influenced corrosion (MIC) on the internal corrosion of WIPs. The project focuses particularly on the influence of the sulfate reducing bacteria (SRB...

...Uniform and pitting corrosion are the two main forms of corrosion associated with sulfate reducing bacteria (SRB). ¹ The damaging effects caused by pitting are typically much more severe than those by uniform corrosion. Pitting leads to perforation or crack initiation and, accordingly...
