采用不同的碳水化合物纯溶液和混合溶液，研究了开菲尔颗粒在充气旺盛的间歇系统中的繁殖。在30℃，含单糖的合成液体培养基中，含有果糖(pH值5.5，5g/L初始开菲尔浓度)的液体培养基产生量最大，在24小时内达20.75g。当使用糖的混合物时，葡萄糖和蔗糖的固定比例为1：3，被发现是最有效的，产生27.25克开菲尔生物量。对糖的生物转化动力学也进行了研究。研究结果对有效、低成本利用各种食品级废弃物生产开菲尔生物质以及将其用作一种新型的烘焙发酵剂具有重要意义。(C)2004爱思唯尔有限公司。保留所有权利。
The propagation of kefir grains in a vigorously aerated, batch system, using variousipure and mixed solutions of carbohydrates, was studied. From the experiments performed at 30 degreesC with synthetic liquid media containing single sugars, the one containing fructose (pH 5.5 and 5 g/l initial kefir concentration), gave the largest biomass production (20.75 g) in a 24-h experiment. When mixtures of sugars where used, the one containing glucose and sucrose at a fixed-ratio of 1:3, was found to be the most effective, yielding 27.25 g of kefir biomass. Kinetics of sugar bioconversions were also studied. The obtained results are important for the prediction of effective, low-cost utilization of various food-grade wastes for the production of kefir biomass and its possible use as a novel baking starter.
