Determination of the amount of LA in lactobacilli supernatant. (A) HPLC analysis of LA content in the supernatants of L. crispatus and L. reuteri. Statistical significance was calculated vs. control (* p ≤ 0.01). (B) Specific activity of LDHD in bacterial lysates (*** p ≤ 0.0001). Results are expressed as nanomoles (nmol) of LA/mL of supernatant containing 109 CFU of lactobacilli (panel A) and as nanomoles (nmol) of lactic acid min−1/109 CFU (panel B). Bars represent mean values, and error bars represent standard deviation. All measurements were performed in duplicate on six separate occasions.
