This study aims to investigate the effect of fructooligosaccharide (FOS) (0.5, 1, 2, 3, and 4%) supplementation on the growth and survival of and in glucose, fructose, lactose, and sucrose (2, 3, and 4%) systems with 24-h growth and 10-day survival assays at 37 °C. FOS supplementation showed a higher growth-promoting effect on than in various sugar systems. The highest percentage of increase in growth index, 78.5%, was observed with 4% sucrose supplemented with 0.5% FOS in . In comparison, the highest percentage increase in growth index, 5.6 and 6.6%, was observed in the presence of 2% glucose and 4% lactose supplemented with 0.5% FOS in . In survival assay, FOS supplementation (0.5-4%) in a 2% lactose system showed the highest positive effect on the cell viability of on day-10. As for , FOS supplementation (1 and 2%) in the 2% sucrose system showed the highest positive effect on the cell viability, followed by FOS supplementation (0.5, 3, and 4%) in 2% sucrose and FOS supplementation (3 and 4%) in 2% lactose on day-10. This study demonstrated that the efficacy of FOS supplementation was depended on its concentration, sugar system and its concentration, and strain.

本研究旨在通过在37°C下进行24小时生长和10天存活试验，研究低聚果糖（FOS）（0.5%、1%、2%、3%和4%）添加量对在葡萄糖、果糖、乳糖和蔗糖（2%、3%和4%）体系中的生长和存活的影响。在各种糖体系中，添加FOS对的生长促进作用高于。在中，添加0.5%FOS的4%蔗糖组生长指数增加百分比最高，为78.5%。相比之下，在中，添加0.5%FOS的2%葡萄糖组和4%乳糖组生长指数增加百分比最高，分别为5.6%和6.6%。在存活试验中，2%乳糖体系中添加FOS（0.5 - 4%）对第10天的细胞活力显示出最高的积极影响。对于，在2%蔗糖体系中添加FOS（1%和2%）对细胞活力的积极影响最高，其次是在第10天2%蔗糖中添加FOS（0.5%、3%和4%）以及2%乳糖中添加FOS（3%和4%）。本研究表明，添加FOS的效果取决于其浓度、糖体系及其浓度以及菌株。
