Porphyromonas gingivalis is an etiologic agent of periodontal disease in humans. The disease is associated with the formation of a mixed oral biofilm which is exposed to oxygen and environmental stress, such as oxidative stress. To investigate possib

International audience; Iridescence is an original type of colouration that is relatively widespread in nature but has been either incompletely described or entirely neglected in prokaryotes. Recently, we reported a brilliant 'pointillistic' iridesce

Iridescent color appearances are widespread in nature. They arise from the interaction of light with micron- and submicron-sized physical structures spatially arranged with periodic geometry and are usually associated with bright angle-dependent hues

Effect of abiotic factors on the unique glitter-like iridescence of Cellulophaga lytica

Autor: Eric Rosenfeld, Pauline Marie, Betty Kientz

Publikováno v: FEMS Microbiology Letters. 333:101-108

Iridescence is a property of structural color that has been poorly documented in the prokaryotic kingdom. We recently isolated a Cellulophaga lytica strain that exhibits, on solid media, a unique intense glitter-like iridescence in reflection. Irides
