LACTIC ACID BACTERIUM HAVING EFFECT OF LOWERING BLOOD URIC ACID LEVEL

摘要

It is intended to provide a lactic acid bacterium which is suitable for food and drink or medicinal use and is capable of suppressing an increase in blood uric acid level. Various lactic acid bacteria were cultured in the presence of purine bodies, a consumption amount of the purine bodies and a production amount of degradation product of purine bodies were measured, and plural lactic acid bacteria exhibiting a remarkable degradation ability of purine bodies were selected. Each of the lactic acid bacteria determined to have a high degradation ability of purine bodies by the selection was orally administered to rats fed with a diet containingpurine bodies, the performance status and serum uric acid level of the rats were measured, and an effect of administration of lactic acid bacterium on the serum uric acid level was examined. As a result, a lactic acid bacterium: Lactobacillus gasseri OLL2922 capable of significantly suppressing an increase in serum uric acid level was found.
