制鞋工业中用于抑菌处理的甘油-酸酯

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(MAG C 8:0),甘油一癸酸酯(MAG C10:0),甘油-2-乙基乙酸单酯(MAG 2Eth-C 6:0)和甘油一月桂酸酯(MAG C 12:0),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MAG C 8:0和MAG C 10:0敏感.在100～150mg/L的浓度范围内MAG C 8:0和MAG C10:0抑制微生物生长.纤维霉菌特别受到MAG C 8:0(100mg/L)溶液的抑制.当这一浓度的MAG C 8:0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 Monoacylglycerols as Microbicidal Treatment in Shoemaking Industry

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.
