Cell-Wide Responses to Low-Oxygen Exposure inDesulfovibrio vulgarisHildenborough

The responses of the anaerobic, sulfate-reducing organism Desulfovibrio vulgaris Hildenborough to low-oxygen exposure (0.1% O 2 ) were monitored via transcriptomics and proteomics. Exposure to 0.1% O 2 caused a decrease in the growth rate without affecting viability. Concerted upregulation of the predicted peroxide stress response regulon (PerR) genes was observed in response to the 0.1% O 2 exposure. Several of the candidates also showed increases in protein abundance. Among the remaining small number of transcript changes was the upregulation of the predicted transmembrane tetraheme cytochrome c 3 complex. Other known oxidative stress response candidates remained unchanged during the low-O 2 exposure. To fully understand the results of the 0.1% O 2 exposure, transcriptomics and proteomics data were collected for exposure to air using a similar experimental protocol. In contrast to the 0.1% O 2 exposure, air exposure was detrimental to both the growth rate and viability and caused dramatic changes at both the transcriptome and proteome levels. Interestingly, the transcripts of the predicted PerR regulon genes were downregulated during air exposure. Our results highlight the differences in the cell-wide responses to low and high O 2 levels in D. vulgaris and suggest that while exposure to air is highly detrimental to D. vulgaris, this bacterium can successfully cope with periodic exposure to low O 2 levels in its environment.

“…Although the microbial communities in oil and gas fields have been analyzed extensively (3,5,12,17,21), those inhabiting the walls of pipelines transporting oil, water, or gas are only beginning to be characterized (10,15,18,20,25,26,31). Yet understanding these communities is highly relevant, as they contribute to microbially influenced corrosion (MIC), which, along with other forms of corrosion, can lead to pipeline failure.…”

“…This offers a unique opportunity to determine the microbial community composition at defined pipeline locations. Pipe wall community compositions are typically determined through analysis of pigging solids, obtained by scraping an entire pipeline with a spherical metal pig (10,26), or by placing metal coupons in a pipeline that are removed after a certain period of time (15,18,20). Neither method represents sections of pipe that correspond to actual corrosion failures.…”

Pipelines transporting brackish subsurface water, used in the production of bitumen by steam-assisted gravity drainage, are subject to frequent corrosion failures despite the addition of the oxygen scavenger sodium bisulfite (SBS). Pyrosequencing of 16S rRNA genes was used to determine the microbial community composition for planktonic samples of transported water and for sessile samples of pipe-associated solids (PAS) scraped from pipeline cutouts representing corrosion failures. These were obtained from upstream (PAS-616P) and downstream (PAS-821TP and PAS-821LP, collected under rapid-flow and stagnant conditions, respectively) of the SBS injection point. Most transported water samples had a large fraction (1.8% to 97% of pyrosequencing reads) of Pseudomonas not found in sessile pipe samples. The sessile population of PAS-616P had methanogens (Methanobacteriaceae) as the main (56%) community component, whereas Deltaproteobacteria of the genera Desulfomicrobium and Desulfocapsa were not detected. In contrast, PAS-821TP and PAS-821LP had lower fractions (41% and 0.6%) of Methanobacteriaceae archaea but increased fractions of sulfate-reducing Desulfomicrobium (18% and 48%) and of bisulfite-disproportionating Desulfocapsa (35% and 22%) bacteria. Hence, SBS injection strongly changed the sessile microbial community populations. X-ray diffraction analysis of pipeline scale indicated that iron carbonate was present both upstream and downstream, whereas iron sulfide and sulfur were found only downstream of the SBS injection point, suggesting a contribution of the bisulfite-disproportionating and sulfate-reducing bacteria in the scale to iron corrosion. Incubation of iron coupons with pipeline waters indicated iron corrosion coupled to the formation of methane. Hence, both methanogenic and sulfidogenic microbial communities contributed to corrosion of pipelines transporting these brackish waters.

“…In three-electrode system test coupons of 1.0 cm 2 areas exposed as working electrode, a high purity platinum sheet as a counter electrode and saturated calomel electrode was used as a reference electrode [14]. Experiments were carried out in electrochemical workstation model 600 D/E series in without and with the addition of an inhibitor, a stabilization period of 30 min was allowed, which is enough to attain stable OCP value.…”

Several studies of biofilms must accept that biofilms may develop in an enormous number of environments. This biofilm forms colonization on the solid surfaces by extracellular polysaccharides (EPSs) secreted by the microbial cells. The EPSs secreted by microbial cell stimulate corrosion in the engineered materials due to the presence of polyanionic neutral macromolecules. Many techniques have been described measuring and inhibiting microbiologically influenced corrosion; however, none has been accepted as an industry standard. This is because the risks posed to the marine biosphere due to the use of antifouling inhibitors. Recently, a large amount of literature has been edited on the influence of toxic biocides on nontargeted organisms in the marine environment are most likely. It has been shown that the modifications of antifouling inhibitors by the non-toxic drugs can reduce microbial adhesion and some disentangle effects toward the environment. Hence, in this paper, the inhibition effect of neomycin trisulfate on the Klebsiella oxytoca on mild steel corrosion has been investigated using weight loss measurement, electrochemical impedance spectroscopy, Fourier-transform infrared, and scanning electron microscopy (SEM). These studies have shown that neomycin trisulfate shows better inhibition toward the microbe. The agreement with the experimental data was also found to be satisfactory. Further, surface morphological examination through SEM confirms that the inhibitor inhibits the microbes by blocking the EPS.
