Optical density measurements of the influence of P. acnes fermentation products on the growth of S. aureus.

Optical density of <i>S. aureus</i> samples incubated with the supernatant from <i>P. acnes </i>cultures. <i>P. acnes</i> was cultured in Luria broth medium in the absence ( n = 5) or in the presence ( n = 5) of glycerol for five days. Subsequently, the cultures were centrifuged at 5000 rpm for 30 minutes and the supernatant was used as the medium to culture <i>S. aureus</i> in various concentrations. Here either with 6.25 % supernatant or 100% supernatant.

本数据集为经痤疮丙酸杆菌（*P. acnes*）培养液上清孵育的金黄色葡萄球菌（*S. aureus*）样本的光密度（optical density）数据。痤疮丙酸杆菌（*P. acnes*）分别在不含甘油（n=5）或含甘油（n=5）的LB培养基（Luria broth）中培养5天。随后将培养液以5000转每分钟（rpm）的转速离心30分钟，收集上清液，以此配制培养基培养不同浓度的金黄色葡萄球菌（*S. aureus*），实验组分别设置为6.25%上清液组与100%上清液组。
