This work was designed to determine chemically inert mercury-selenium (Hg-Se) compounds formed in a culture of Pseudomonas fluorescens exposed to Hg(2+) and Se(IV) (selenite). To isolate these compounds, different digestion methods were studied and sodium dodecyl sulfate (SDS) lysis was selected. The Hg(0) and non-reactive Hg were determined in two series of cultures containing 0.0-6.00 μg L(-1) Se(IV) (0.0-76.0 μmol L(-1)) in combination with low 5.00 μg L(-1) (0.025 μmol L(-1)) or high 100 μg… CONTINUE READING
