Study of a Sulfate Reducing Bacteria Gene expression to better understanding the mechanism of h2s production and dsrab gene expression
Abstract
This project intends to investigate the expression of the dsrAB gene, presentonly in the sulfate reducing bacteria, through the different concentrations of a givenstimulus. Originally a culture quantification method, the Most Probable Number (MPN),is used to indicate the treatment against SRBs, but there are no studies demonstratingthe activity of these bacteria in the field or in vitro. Thus, there is a possibility that theMPN may be underestimating SRBs impacts, since a SRB group with high metabolicactivity of the dsrAB gene may cause greater structural or occupational damage than amuch larger number of bacteria, but that have a lower rate of metabolic activity.This study can contribute on mitigation of biocorrosion in fuel tanks, ballast tanks,pipelines that can be propitious to the growth of this group of bacteria. Reducing costsof maintenance and risks for operators.
