Figure 6

Operons for sulfur oxidation and nitrate reduction present in the dominant Gammaproteobacteria genotypes. Those shown here are present in the SG8-45 bin. However, syntenous operons are also present in several other Gammaproteobacteria bins (SG8-11, SG8-15, SG8-45, SG8-47, SG8-50, STMZ1-46, and SMTZ-46).
