摘要：

优化离心力、离心时间和离心温度等离心参数，研究其对双歧杆菌存活力的影响。确定了在4℃，6000g离心时间30min的条件下，长双歧杆菌KLDS 2.0001和婴儿双歧杆菌KLDS 2.0002两菌株的存活率最高，分别达到了94.49%和91.19%。

Abstract:

The centrifugal conditions such as centrifugal force, time and temperature were optimized. The results showed that the highest harvesting rates of viable cells of B. longum KLDS 2.0001 and B. infantis KLDS 2.0002 were 94.49% and 91.19% respectively under 6000g at 4℃ for 30min.
