ΔOD600, maximum minus minimum optical density reading (at 600 nm); lag phase, length of time culture remains at <10% of maximum OD; T half max, time taken to achieve half-maximal culture growth [(maximum OD minus minimum OD) times 0.5]; max DT, maximum observed doubling time; FLC, fluconazole; VRC, voriconazole; AMB, amphotericin B. R6G efflux values indicate ratios of fluorescence to forward scatter (FSC/FL-2) for 1.2 × 104 cells. The highest values are in boldface; —, not detected.
Other (not lanosterol) 14α-methylated sterols.
