摘要

研究了不同实验条件下痤疮丙酸杆菌菌落的荧光光谱。光谱在580nm和620nm处有峰。这些波段是由两种不同的成分造成的;580 nm的成分可能是金属卟啉,620 nm的成分可能是比例卟啉。580 nm荧光被光和氧的共同作用破坏(在严格的厌氧条件下无破坏)。中断漂白光的黑暗时期在黑暗时期停止了这一成分的破坏。最初产生的620nm成分是由于氧暴露。在光照射下,这种成分后来被氧和光的共同作用所破坏。

Photodestruction of Propionibacterium acnes porphyrins.

The fluorescence spectra of colonies of 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 metalloporphyrin, and there are indications that the 620 nm component could be a coproporphyrin. The 580 nm fluorescence was destroyed by the combined action of light and oxygen (no destruction under strict anaerobic conditions). A dark period interrupting the bleaching light stopped the destruction of this component for the time of the dark period. The initial production of the 620 nm component was due to the oxygen exposure. Upon light irradiation this component was later destroyed by the combined action of oxygen and light.
