Acetate Utilization Is Similar in All Strains.
sta6 (black) and three independent STA6 strains (STA6-C2, STA6-C4, and STA6-C6; shown in white) were cultured in +N to a density of 4 × 106 cells mL−1 before transferring to –N cultures to a final cell density of 2 × 106 cells mL−1. Acetate levels in the supernatant were assessed at 0, 48, and 96 h after transfer to –N. Error bars represent one sd.
