to an increase in reactive oxygen species content. The synergistic effect of fluconazole resulted in a reduction in the azole concentration required for yeast inhibition. We observed changes in the color of the yeast cultures; thus, we conducted experiments to prove that the carotenoid profile was altered. The addition of lactones also triggered a decline in fatty acid methyl esters.
目前,由机会性粘液红酵母菌株引起的真菌感染病例不断增加,主要发生在住院期间免疫功能低下的患者中。过量使用抗生素和唑类化合物会增加微生物耐药性的风险。这些药物的新替代品可能是合成的苯酞内酯,其结构与芹菜植物中的天然内酯相同或相似,具有低毒性和相对较高的抑菌活性。在本研究中,测定了七种苯酞内酯对 R. mucilaginosa IHEM 18459 的抑菌活性。我们发现,微量稀释测试中选择的最有效的化合物 3-正丁苯酞,会导致干酵母生物量呈剂量依赖性下降。 。苯酞在酵母细胞中积累,导致活性氧含量增加。氟康唑的协同作用导致酵母抑制所需的唑浓度降低。我们观察了酵母培养物颜色的变化;因此,我们进行了实验来证明类胡萝卜素的分布发生了改变。内酯的添加也引发了脂肪酸甲酯的下降。
