FIG 7

Bacterial growth (optical density at 600 nm [OD600]) of the S. loihica PV-4, the in-frame deletion mutants Δcrp1, Δcrp2, and ΔnirK, and the Δcrp1 ΔnirK double mutant under different C/N ratios (high carbon/nitrogen ratio means a C/N ratio of 12 and low carbon/nitrogen ratio means a C/N ratio of 2) between anaerobic and aerobic conditions.
