Characterization of Brevibacterium linens pigmentation using spectrocolorimetry

Spectrocolorimetry was used for the evaluation of Brevibacterium linens pigmentation. A total of 23 strains of Brevibacterium linens, from various sources, were plated onto solid agar media and their color coordinates were measured and expressed by the L*a*b* colorimetric system. All the strains were located along a straight line with a hue of 66° (orange color). The effect of light exposure versus storage in the dark was also investigated using this approach. Three groups with distinct behaviors were demonstrated for the 23 B. linens strains.
