 Title    Photodestruction of Propionibacterium acnes Porphyrins  
 Abstract    The fluorescence spectra o f colonies o f Propionibacterium acnes were studied under various experimental conditions. The spectra contained peaks at 580 nm and 620 nm. These bands were due to two different components; the 580 nm component was likely to be a m etalloporphyrin, and there are ind ica­ tions that the 620 nm component could be a coproporphyrin. The 580 nm fluorescence was destroyed by the com bined action o f light and oxygen (no destruction under strict anaerobic conditions). A dark period interrupting the bleaching light stopped the destruction o f this component for the time o f the dark period. The initial production o f the 620 nm com ponent was due to the oxygen exposure. U pon light irradiation this component was later destroyed by the com bined action o f oxygen and light.
