Technical Abstract: This study used 1321 base pair 16S rRNA gene sequence methods to confirm the phylogenetic position of a soil isolate as a bacterium belonging to the genus Pesudomonas sp. Morphological, biochemical characteristics, and fatty acid profiles are consistent with the 16S rRNA gene sequence identification of the bacterium. The isolate was obtained from a soil sample. The 16S rRNA gene sequence shows that the strain has a > 1% sequence divergence from other named species of Pseudomonas and likely represents a new species of the genus. The bacterium shows a unique resistance to the oxyanions of selenium and this bacterium, or perhaps its enzymes or DNA, might be useful for the remediation of waters contaminated with selenite. The most economical approach for removing many contaminants from water is to employ biological methods that require the use of microorganisms. Thus, it is important that bacteria that are capable of removing harmful compounds from ground and surface waters be isolated, characterized, and identified. It is also important to know what organisms might accumulate in biobarriers used for remediation.
