Fatty acid composition (%) ¹ in S. aureus Pig1 grown at stationary phase ² in glucose or acetate containing LB broths.

Fatty Acids	LB	LB-MOPS-Glucose	LB-MOPS-Acetate
SCSFA	9.2 ± 0.30	38.0 ± 1.00	27.1 ± 0.04
BCFA	90.8 ± 0.28	61.9 ± 0.95	62.8 ± 0.15
Unknown	nd	nd	10.2 ± 0.11

¹ Standard error of the mean (SEM) in the % of each fatty acid was determined from two independent fatty acid analysis experiments; ² Fatty acid analysis was done for the stationary phase (12 h grown) cells that had significant differences in pigment production (see Table 6). nd, not detected.
