Figure 6From: Enzymatic activity of Lactobacillus reuteri grown in a sweet potato based medium with the addition of metal ions Relative activity (%) of phytase produced by L. reuteri grown in 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 ion divided by the enzymatic activity in SPM without metal ions then multiplied by 100.Back to article page
