a
Cells harvested for RNA while carrying out thiosulfate oxidation and denitrification (see Materials and Methods).
b
Cells harvested for RNA while carrying out oxidation of Fe(II) (in FeCO3) and denitrification (see Materials and Methods).
c
Comparison made to the number of transcripts for Tbd2480 under thiosulfate-induced conditions. The transcript copy number for Tbd2480 under these conditions was relatively high (in the copy number range of Tbd0562 and Tbd0561, which encode subunits of nitric oxide reductase, a key enzyme involved in denitrification).
d
By definition.
e
NA, not analyzed.
