Lactic acid bacterium having purine body uptake ability, and use thereof

Provided is a method for obtaining a lactic acid bacterium having a property of reducing a serum uric acid level. The present invention relates to: a method for screening for a lactic acid bacterium, which comprises determining the amount of a purine body incorporated in each of lactic acid bacteria in a culture medium containing the purine body and then screening for a lactic acid bacterium having a property of trapping the purine body among the lactic acid bacteria employing the amount as a measure; and a purine body trapping agent for reducing a serum uric acid level, which comprises a lactic acid bacterium obtained by the method.
