Deletion of fbiC in Streptomyces venezuelae removes autofluorescence in the excitation-emission range of cyan fluorescent protein
Autofluorescence poses an impediment to fluorescence microscopy of biological samples. In the Gram-positive, soil-dwelling bacteria of the genus Streptomyces, sources of autofluorescence have not been examined systematically to date. Here, we show that the model organism for the genus, Streptomyces venezuelae, shows autofluorescence in two of the commonly used fluorescence channels for visualizing
