Strains of P.a. were isolated from seborrheic filaments from 11 persons and investigated according to their production of porphyrins. After growing the organisms during a 5 resp. 10 days cultivation period on solid as well as in liquid culture medium the quantity and quality of the bacterial porphyrins were determined. There existed intense variations in quantity not only when the special strains were compared with each other but also when the same strains were treated with different preparations. The porphyrin-spectrum, as demonstrated by thin-layer-chromatography, showed porphyrins with 2--8 carboxyclic groups, the coproporphyrin standing out in most cases as the most intense band.
从11人的脂溢性细丝中分离出痤疮丙酸杆菌菌株，并根据其卟啉生成情况进行研究。在固体及液体培养基中培养这些微生物5天或10天后，测定细菌卟啉的数量和质量。不仅在比较不同菌株时，而且在相同菌株用不同制剂处理时，数量上都存在显著差异。薄层色谱法显示的卟啉光谱表明，存在含2 - 8个羧基的卟啉，在大多数情况下，粪卟啉作为最明显的条带突出显示。
