Phylogenetic analysis

Fe (III) compounds which are formed from the oxidation of Fe(II) by iron bacteria precipitates, and forms iron oxides - an extensive orange mats of organic material, which is often found present in the ground water, evident by the rust stain colour seen on almost all the water storage tanks in Yenagoa, Bayelsa State, Nigeria. Hence, this study characterized iron bacteria diversity in groundwater, which is a major source of drinking water in the state.

Phylogenetic and functional gene analysis of sulphate-reducing bacteria (SRB) from crude oil and produced water was carried out using molecular methods. The concentration of hydrogen sulphide (H2S) produced by SRB, as an indication of SRB presence, was determined using spectrophotometric sulphide assay. More H2S was observed to be produced at 55 ˚C than at 30 ˚C, with sample B found to produce more H2S at these temperatures than sample A. This implies more SRB contamination in sample B, possibly from subterranean water.
