摘　　要：本研究旨在考察一种经喜马拉雅食品来源酿酒酵母和副干酪乳杆菌发酵而得的滤液复合物(SLFC)对面部细菌微生态和皮肤屏障的调节作用。筛选有皮肤衰老迹象女性30人(30~45岁,平均年龄38岁),对比使用SLFC前(D0)和使用28天后(D28)两组样本,面部细菌物种Alpha多样性显著降低(p<0.05);Beta多样性分组有意义(p<0.05);在ASV(amplicon sequence variants)水平上考察物种组成,结果显示葡萄球菌属丰度显著增加(p<0.05),丙酸杆菌属、棒状杆菌属、不动杆菌属等皮肤常驻菌的相对丰度保持稳定,链球菌属、红球菌属、水栖菌属、黄杆菌属等机会致病菌的丰度下降。对皮肤特征菌检测,结果显示表皮葡萄球菌的丰度显著提高(p<0.05);痤疮丙酸杆菌丰度变化不显著;金黄色葡萄球菌则无检出。D28组消费者反馈肌肤平滑、光泽和保湿状态得到改善,此外肌肤泛红得到缓解。由此可得,发酵产物复合物SLFC能有效调节并稳定面部菌群微生态平衡,巩固皮肤屏障。The objective of this study was to investigate the effects of a Himalaya-derived Saccharomyces and Lactobacillus ferment complex(SLFC)on the facial micro-ecology.Thirty women(30-45 years old,average 38 years old)with signs of skin aging used SLFC.Compared with the two groups of samples before use(D0)and after 28 days of use(D28),the Alpha diversity of facial bacterial species decreased significantly and the Beta diversity had obvious differentiation in different regions.The relative abundance of Staphylococcus increased significantly.The relative abundance of Propionibacterium,Corynebacterium,Acinetobacter,and other skin resident bacteria remained stable.The relative abundance of the opportunistic pathogenic bacteria such as Streptococcus,Erythrococcus,Aquatic bacteria and flavobacterium decreased.At the species level,the abundance of Staphylococcus epidermidis increased significantly,the abundance of Cutibacterium acnes did not change significantly,and Staphylococcus aureus was not detected.According to the feedback of consumers after treatment with SLFC for 28 days,skin smoothness,gloss and moisture were improved and the skin redness was relieved.Therefore,SLFC can effectively regulate and stabilize the microecological balance of facial flora to improve and strengthen the skin barrier.
