* All cultures amended with 0.1 or 1 mM tellurate turned black from elemental tellurium formation whether selenate was present or not; cultures of R. rubrum G9 turned black in the first few days, but then the black color slowly disappeared over the next few days.

& The unit is integrated area x 10-6.
