FIG. 4.
Growth data for 11168-O and 11168-GS cultured for 26 h microaerobically or under severe O2 limitation. At the 0-h time point, overnight mid-log cultures were diluted back to an OD600 of 0.1 and samples were taken for CFU analysis. The OD600 (A) and number of CFU per milliliter (B) were determined at 2, 6, 10, and 26 h after back dilution. Circles are microaerobic 11168-GS; diamonds are microaerobic 11168-O; squares are severely O2-limited 11168-GS; and triangles are severely O2-limited 11168-O.
