Porphyromonas gingivalis

From MicrobeWiki, the student-edited microbiology resource
P. gingivalis colonies grown on blood agar.[1] Heme from the media is oxidized by the bacteria to produce hemin which accumulates on the cell surface producing a characteristic black pigment after about 7 days of anaerobic incubation.[2]
