Levan, a polysaccharide from Zymomonas mobilis, was hydrolyzed to obtain oligofructans or fructooligosaccharides with a degree of polymerization varying from 4 to 14. Fructooligosaccharides (FOS) are short chain fructans that beneficially affects the host by selective stimulation of growth and activity of one or a number of bacteria including probiotic bacteria in the colon. The hydrolysis was performed in a microwave oven to shorten the reaction time. The experiments showed that it is possible to maximize selected oligomers by interrupting the hydrolysis at the due time. The results allow one to infer that the procedure may also be useful for production of oligomers from other polysaccharides.
来自运动发酵单胞菌的多糖果聚糖被水解以获得聚合度在4至14之间变化的低聚果糖或低聚果糖。低聚果糖（FOS）是短链果聚糖，通过选择性刺激结肠中一种或多种细菌（包括益生菌）的生长和活性而对宿主产生有益影响。水解在微波炉中进行以缩短反应时间。实验表明，通过在适当时间中断水解，可以使选定的低聚物最大化。结果使人们可以推断该方法也可能有助于从其他多糖生产低聚物。
