Fig. 3From: The effect of in vitro simulated colonic pH gradients on microbial activity and metabolite production using common prebiotics as substratesDifferentially abundant taxa between changed colonic pH. The top 20 differentially abundant taxa with the lowest p-adjust value were selected by Deseq2 and labeled with * in the heatmap, indicating the significantly altered taxa from the respective between-group comparison. Row-wise Z-score scaling was conducted in the heatmap visualization, showing the normalized relative abundance by the mean of the specific taxa across all samples. D, donorBack to article page
