    Effect of Cadmium(II), Chromium(VI), and Arsenic(V) on Long-Term Viability- and Growth-Inhibition Assays Using Vibrio fischeri Marine Bacteria

    As a complement to previous results obtained using the standard Microtox acute-toxicity test, which is based on measuring the rapid decrease of bioluminescence (5 to 30 minutes of exposure) in Vibrio fischeri bac...

    Effect of pH on Arsenate and Arsenite Toxicity to Luminescent Bacteria (Vibrio fischeri)

    Arsenic is an abundant metalloid and a dangerous pollutant when in solution under the arsenate or arsenite forms—As(V) and As(III), respectively. Since its biological effects are expected to depend on the oxid...
