a Alpha diversity (number of genera) for all (n = 31) high protein powder metatranscriptomes is compared to the total number of sequenced reads for a range of in silico subsampled sequencing depths. The dashed vertical line indicates the medial elbow (at ~ 67 million reads). b Hierarchical clustering of Aitchison distance values of poultry meal samples based on microbial composition. Samples were received from Supplier A (blue and red) and Supplier B (green). Matrix-contaminated samples are additionally marked in red.
