摘要
以甘油与不同偶数脂肪酸为原料合成了一系列甘油 酸酯(MAGS):甘油一辛酸酯(MAGC8∶0),甘油一癸酸酯(MAGC10∶0),甘油 2 乙基乙酸单酯(MAG2Eth C6∶0)和甘油一月桂酸酯(MAGC12∶0),测定其抑菌效果。这些材料以乙醇溶液的形式应用于衬里材料上。酵母菌(白色念菌和近平滑假丝酵母)的实验证明这两种酵母菌对MAGC8∶0和MAGC10∶0敏感。在100～150mg/L的浓度范围内MAGC8∶0和MAGC10∶0抑制微生物生长。纤维霉菌特别受到MAGC8∶0(100mg/L)溶液的抑制。当这一浓度的MAGC8∶0溶液应用于被测材料时,黑曲霉、点状毛霉、赭绿青霉具有抵抗性。实验证明,各种MAGS对不同种类可造成霉菌病的真菌微生物的防霉效果不同。
The microbicidal effects of monoacylglycerols (MAGs) prepared from glycidol and fatty acids with even-numbered carbons in the chain caprylic (MAG C 8∶0), capric(MAG C 10∶0), 2-ethylcaproic (MAG 2Eth-C 6∶0) and lauric (MAG C 12∶0) -were tested. These were consequently applied as ethanolic solution to lining materials. The experiments with yeasts Candida albicans and Candida parapsilosis proved their sensitivity to MAG C 8∶0 and MAG C 10∶0, which suppressed the growth of microorganisms with concentrations from 100 to 150 mg/L. The fibrous moulds were especially inhibited by the solution of MAG C 8∶0 (100 mg/L). When this concentration was applied to tested materials the used moulds Aspergillus niger, Mucor racemosus and Penicillium ochrochloron showed themselves to be resistant against MAG C 8∶0. The particular types of MAGs thus proved a different antimycotic effectivity to various types of fungal microorganisms causing mycoses.
