| Abstract: | Lactobacillus casei(L.casei ATCC 7469) and Streptococcus faecalis(S.faecalis ATCC 8043) as the testing bacteria for the detection of folic acid were compared.The results showed that the detection period of S.faecalis was one day shorter than that of L.casei,and the operation was easy to handle.Comparison of the reproducibility of the testing results by the two bacteria showed no significant difference(P>0.05),neither did the results of the two methods(P>0.05). |
