Figure 3From: Enzymatic activity of Lactobacillus reuteri grown in a sweet potato based medium with the addition of metal ions Relative activity (%) of α -glucosidase produced by L. reuteri grown is SPM with added metal ions compared to the control group without metal ions. The relative activity was calculated as the enzymatic activity in SPM with added metal ions divided by the enzymatic activity in SPM without metal ions then multiplied by 100.Back to article page
