Abstract
The present invention provides lactic acid bacteria having oxalic acid-degrading activity several times higher than those of conventionally known lactic acid bacteria having an oxalic acid-degrading activity, and uses thereof. Lactic acid bacteria capable of degrading a large amount of oxalic acid were screened from 132 strains of Lactobacillus lactic acid bacteria that have been independently isolated from feces and gastric juices of human adults. As a result, lactic acid bacteria having an oxalic acid degradation rate of 50% or more when cultured at 37° C. for 72 hours in a culture medium containing 10 mM oxalic acid at pH 6.5 at the start of culture were discovered.
