Figure 1.

Light-dependent carotenoid-like pigment production of isolates and genome-sequenced bacteria. Light-dependent phenotype of strains grown at 28 °C under dark and blue light conditions for 24 h. The culture media used are shown in Table 1 (isolates) and Table 2 (strains obtained from culture collections). Colonies grown under light conditions appear vivid or pale yellow, whereas those grown under dark conditions appear white or cream.
