* 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.
