Pathogenic and spoilage fungi cause enormous challenges to food related fatal infections. Plant essential oil based classical emulsions can functions as antifungal agents. To investigate the antifungal spectrum, that is the scope of the nanoemulsion composed of Cleome viscosa essential oil and Triton-x-100 fabricated by ultrasonication method. Minimum inhibitory and fungicidal concentration of essential oil nanoemulsion (EONE) was tested against food borne pathogenic C. albicans. The MIC and MFC values ranged from 16.5 to 33 µl/ml with significant reduction on biofilm of C. albicans isolates. The alteration of molecular fingerprints was confirmed by Fourier transformed infrared spectroscopy and subsequent reduction of chitin levels in cell walls was noted by spectroscopic analysis. The EONE and their bioactive compounds cause collateral damage on C. albicans cells.
致病真菌和腐败真菌给与食品相关的致命感染带来了巨大挑战。基于植物精油的传统乳液可作为抗真菌剂。为了研究抗真菌谱,即通过超声法制备的由白花菜精油和吐温 -x-100 组成的纳米乳液的范围。测试了精油纳米乳液(EONE)对食源致病性白色念珠菌的最低抑菌浓度和杀菌浓度。MIC 和 MFC 值范围为 16.5 至 33 μl/ml,对白色念珠菌分离株的生物膜有显著降低作用。通过傅里叶变换红外光谱证实了分子指纹的改变,并且通过光谱分析注意到细胞壁中几丁质水平随后降低。EONE 及其生物活性化合物对白色念珠菌细胞造成附带损害。
