is one of the most common microorganisms and causes foodborne diseases. In particular, biofilm-forming is more resistant to antimicrobial agents and sanitizing treatments than planktonic cells. Therefore, this study aimed to investigate the anti-biofilm effects of cell-free supernatant (CFS) of isolated from cucumber compared to grapefruit seed extract (GSE). CFS and GSE inhibited and degraded biofilms. The adhesion ability, auto-aggregation, and exopolysaccharide production of CFS-treated , compared to those of the control, were significantly decreased. Moreover, biofilm-related gene expression was altered upon CFS treatment. Scanning electron microscopy images confirmed that CFS exerted anti-biofilm effects against . Therefore, these results suggest that S. cerevisiae CFS has anti-biofilm potential against strains.
是最常见的微生物之一，可引起食源性疾病。特别是，与浮游细胞相比，生物膜形成的 对抗菌剂和消毒处理更具抵抗力。因此，本研究旨在研究从黄瓜中分离出的细胞无细胞上清液（CFS）与柚籽提取物（GSE）相比对 生物膜的抑制作用。CFS 和 GSE 抑制和降解 生物膜。与对照组相比，CFS 处理的 的粘附能力、自聚集和胞外多糖产生均显著降低。此外，CFS 处理还改变了生物膜相关基因的表达。扫描电子显微镜图像证实，CFS 对 发挥了抗生物膜作用。因此，这些结果表明，酿酒酵母 CFS 对 菌株具有抗生物膜潜力。
