| transformations of selenate and selenite by stenotrophomonas maltophilia isolated from a seleniferous agricultural drainage pond sediment. | a gram-negative bacterium, identified as stenotrophomonas maltophilia by fatty acid analysis and 16s rrna sequencing, was isolated from a seleniferous agricultural evaporation pond sediment collected in the tulare lake drainage district, california. in cultures exposed to the atmosphere, the organism reduces selenate (seo4(2-)) and selenite (seo3(2-)) to red amorphous elemental selenium (se degrees ) only upon reaching stationary phase, when o2 levels are less than 0.1 mg l(-1). in 48 h, s. malt ... | 2003 | 12662176 |
