FIG. 5.
HPLC chromatograms depicting mycolic acid profiles of M. frederiksbergense LB501T grown on either solid anthracene, excess glucose, or various mixtures of anthracene and glucose as described in Table 1. A distinction was made between bacteria present in suspension and those in biofilms adhering to anthracene crystals. Signal multiplets of mycolic acids eluting after 28 to 30.5, 31 to 34, and 34 to 35 min are designated as m1, m2, and m3, respectively. Values in parentheses represent the ranges of the y axis in milliabsorption units (mAU) at 260 nm. The x axis shows time in minutes.
